The power of the Po

August 27, 2009 9 Comments

“Every river is compelled to flow toward the sea, and it also carries tears with it.”

I don’t know who wrote that, but it is the perfect epigraph for the Po River. And nearly 60 years ago, there were many, many tears.

Those two words — Po River — are tremendously evocative to millions, especially those living near it, or in some way depending on it. It’s the longest river in Italy, and although it isn’t much compared to the Nile or the Congo, it is Italy’s mythic mass of water.

The Po valley comprises some of the richest and most heavily cultivated land in Europe.

The Po flows 405 miles [652 kilometers] from Monviso, a dazzling mountain in the Cottian Alps, to the Adriatic, through the core of the north Italian Padania Plain and drains an area of 28,946 square miles [74,970 square kilometers].

Some people think it’s monotonous and boring, but that’s when it’s just rolling along like Ol’ Man River. Then every once in a while it floods, and turns into something cataclysmic, and suddenly people are praying to God to make it boring again. You can read more in the article I wrote for National Geographic in the May, 2002 issue.

I’m talking about all this because of my chronic curiosity about a statue stuck off by itself amid a few trees near the Giardini vaporetto stop.

It’s dramatic yet curiously detached; nevertheless, you realize something serious is underway. A rescue, obviously, but it isn’t immediately clear what the danger is. It’s the Po.

img_2129-statua-alluvione-comp Catastrophic floods have occurred many times, but in November of 1951 there was a confluence of factors which spelled doom for man, beast, buildings, crops, bridges, soil, and anything else that was in, on, or near the river. People seem to get all worked up about high tide in Venice, but that’s a Gilbert and Sullivan ditty compared to the Wagnerian devastation the Po visited on 200,000 people, nearly 1,000 of whom lost their lives.

I’m not going to try to describe it; the numbers can do it for me. But I do remember what a friend of mine in Cremona told me about the Po in the major flood of 2000: “The river under the bridge sounded like a waterfall.” In 1951, the volume of water was measured at Cremona at 399,055 cubic feet per second [11,300 cubic meters per second] — it must have sounded like the Last Judgment.

That autumn was especially rainy, not only in Italy but elsewhere in Europe and also in the United States. From November 7-13, two weather fronts — one from the Atlantic, the other from Africa — brought rain that wasn’t particularly intense, but it was continuous. In fact, due to the nature and extent of the catchment basin, it’s long rains, rather than intense ones, that create serious floods.

piena515-comp Before long, the ground was saturated, unable to absorb any more water. Then the rain intensified. A hot southeast wind hit the snow that was falling in the Alps, and melted it. More water.

In the five days between November 8-12, 600 billion cubic feet [17 billion cubic meters] of water fell on the Po Plain, the amount which would normally fall in six months.

The Po’s average discharge is 48,400 cubic feet per second [1,370 cubic meters]; at its flood peak in 1951, the Po’s discharge was estimated at almost ten times that, or 424,000 cubic feet [12,000 cubit meters] per second. That would be Niagara Falls doubled, thundering horizontally toward the sea.

The river was rising because many of its 141 tributaries were also rising, obviously. But when some of these smaller rivers tried to empty into the Po, the power of its flow actually forced them back, where they began to flood their own immediate surrounding territory. That southeast wind wasn’t merely melting snow, it was preventing the Po from emptying into the sea.

Nov. 13: During the night, the church bells in Casalmaggiore (Cremona) and Sabbioneta (Mantova) and all the bells in the surrounding towns and villages begin to ring, to summon the men to try to block the rising water. Urgent requests go out for sandbags.

Nov. 14: The Po exceeds 14 feet [4.30 meters]. At 7:00 pm the river bursts its embankments at Paviole di Canaro. An hour later, it breaks through at Bosco and Malcantone at the rate of 211,883 cubic feet [6,000 cubic meters] of water per second. In a few hours 156 square miles [404 square kilometers] are flooded.

When the flood crest reaches the Po Delta, the area also called Polesine, the level is higher at Rovigo — 15.7 feet [4.8 meters] — than any recorded flood ever.

Nov. 15: An emergency truck evacuating people is caught by the water at Frassinelle Polesine; 84 people, including women and children, die in what is remembered as the “death lorry.”

At 2:00 pm the river bursts the banks at Arqua’ Polesine and the water spreads toward Adria.

Nov. 18: Rovigo is evacuated.

Nov. 19: Adria, Cavarzere, Loreo are completely flooded. The cities are evacuated.

Nov. 20: The embankments at Ceserolo are cut to save Rovigo.

Nov. 25: The crest reaches the sea, and the water begins to recede. After three months, toward the end of February, only about one third of the flooded land is still submerged.

In all, some 425 square miles [1,100 square kilometers] were flooded.

The rescue efforts were massive: The Army, Navy, Air Force, firemen, police, Red Cross, Scouts, and volunteers descended on the stricken towns, working continuously with the help of some 2,000 boatmen. People spent days trapped on the roofs of their isolated houses, hoping someone would come by.

bovini-comp The damage in Polesine: 900 houses destroyed, 300 houses damaged, 38 communities flooded, 160,000 people forced to evacuate, 113,000 hectares of farmland flooded, and 300 hectares of land covered by a layer of sand 6 feet [2 meters] deep.

4500 cattle, 150 horses, 7800 pigs, 700 sheep and goats, and one million quintals [220 million pounds] of fodder, all lost.

37 miles [60 kilometers] of embankments and 52 bridges destroyed.

Of course no one had insurance. What was lost was gone forever. It was Biblical.

Contributions poured — excuse the expression — in, from 65 countries, including Uruguay, Tunisia, Haiti, Indonesia, Lebanon, Costa Rica, Somaliland (as it was known), and Albania, as well as NATO.

Lino remembers the effect it had on people in Venice who, like people for miles around, responded by bringing mattresses, clothes, shoes, blankets, and more to collection points around the city. My friend Roberto, from Milan, was just a tyke at the time, but he still remembers his mother telling him he had to donate one of his toys to the children in Polesine, and not just any toy. She decreed, “Your favorite toy.'”

“It was my favorite teddy bear,” he told me, “but I sent it away.”

"To the soldiers of land and sea TKTK" and below it, "To the memory of Alberto Vio, symbol of the generous impulse of Venice for the brothers of Polesine." — "To the soldiers of land and sea Venice salutes the Italians" and below it, "To the memory of Alberto Vio, symbol of the generous impulse of Venice for the brothers of Polesine." On the right side of the pedestal is incised MARZO MDCCCLXXXV and below it, NOVEMBRE MCMLI. The plot thickens.

Many improvements were attempted to prevent anything like this happening again. One of the measures taken was to build ever higher embankments, often (in the cities) walled with concrete. You know how water behaves when it’s forced into a tighter channel or tube? Think of turning on your faucet very hard. Yes. That’s what the Po does now when it floods.

Therefore, when the river floods in spring (melting snow) or autumn (rains), as it will do until snow and rain cease from the earth, it inevitably gains force as it races seaward.

So floods continue — not much anyone can do about that — but the effects are still, if not as catastrophic as in 1951, expensive and distressing. Because houses and fields and poplar forests planted for cellulose keep increasing, and always closer to the river’s edge.

Oh, and some 30 million cubic yards of sand and gravel are illegally dug out of the riverbed for construction every year. Not good if you were looking for ways to minimize flooding, which if you’re a gravel-robber you probably aren’t.

In 1994, the Po flood caused 70 deaths and 10,000 people lost their homes, due mainly to failures in the flood warning system. The human element — always the wild card.

In 2000, the Po flood caused 25 deaths and 40,000 were evacuated.

And so it goes. The Po. Majestic. Magnificent. But I’d never call it monotonous.

NOTE: About the statue with the double inscription: Everyone but me will already have figured it out — it was originally made to commemorate the heroic efforts of the Army to help the victims of the Po flood in the spring of 1882. (I know that the inscription reads 1885, but I am trusting my source, the immortal Giulio Lorenzetti, for this information.) After the inundation of 1951, the statue was recycled to commemorate the equally heroic rescue work (hence the noticeably non-1951 garb of the figures depicted).

Alberto Vio, Lino tells me, was “famous” for having provided boats for the rescue efforts. I don’t know any more than that just now, but it explains why he is mentioned on the plinth. I can tell you, though, that the statue was made by Augusto Benvenuti in 1885, and that it used to stand in Campo San Biagio, the small area in front of the Naval Museum and church of San Biagio. Lino remembers seeing it there when he was a lad. Then someone decided it should move out and they found this anonymous little spot for it by the Giardini. Kind of a modest end to a work that was entitled “Monument to the Italian Army.” But if everybody’s fine with this, so am I.

Watermarks: The sign of “C”

August 13, 2009 3 Comments

It may be that your eye is not drawn wallward as you stroll along the canals of Venice when the tide is low.

Perhaps you don’t find the mats of squishy green clinging to the building foundations very appealing. Perhaps you don’t wish to notice how many small life forms are scurrying around, unhindered by that pesky water. Perhaps there is a general sort of sliminess that reminds you uncomfortably of just how biological the Venetian environment is, and how little the lagoon cares about posing for you and your romantic photographs.

But let’s say those things don’t bother you; let’s say you’re curious to find out what’s beneath the waterline, or almost. If you look carefully, you may very well see this:

img_1928-comune-marino-comp

This incised capital C with the line beneath it is called the “Comune Marino” (hence the “C”), which roughly means “average sea.” Or perhaps “sea average.” This one, as it happens, is in the canal just outside our little hovel.

Water level measurements were formalized in Venice in 1440 when the Water Authority (Magistrato alle Acque) began to measure the upper level of wet algae on canal embankments by carving the letter “C,” which indicated the normal high-tide level. Water fosters certain kinds of algae which flourish in an “intertidal zone”, which is alternately wet and dry, and the line of algae corresponds to the level of water. Obviously.

So “Comune Marino” refers to the line created by the algae, a line which clearly indicates the upper limit of the tide.

Good to know, but why? Because there are many situations in which an engineer would want to know where the average upper limit would be — if he was planning to build a bridge nearby, for example, or even an entire building.

So far, so general. Keep in mind, though, that in each place the “C” is a marker of the average sea level in that canal at that point. Its height only matters in relation to what’s next to it — the water level will be “high” (or low) compared to a building foundation or embankment. If the “C” appears to be going down (or the algae to be going up, like elevators in a French farce) it might indicate that the building is subsiding, or even that the canal is silting up and becoming shallower. Factors such as these all bear some influence on where the average sea level will be in that place and whether you find it innocuous or annoying.

A look at the mark when the tide is out. This illustrates the difficulty of answering the frequent question, "How deep are the canals?" As in, when the tide is high, or when it's low?

An analysis of the displacement of the “algal belt” also gives engineers some idea of the long-term trend of apparent rising of the sea level. This is a subject that is far too great for this little post, but I merely note that the algae is playing its part in informing the world about the state of Venice.

Don’t be too quick, though, to think that just because there’s some algae above the “C” that the city is sinking inexorably into the lagoon. The algae has its own growing period (late winter to early autumn) and if the average high-tide level should rise one year, for one or many of several reasons, the line of algae will also rise. If it should go down the next year, there will be less algae at the previous level. Exceptional peaks in the high-tide level may cause temporary new growth, but it won’t necessarily survive the sunshine and dryness that returns when the tide level goes down.

Algae growth is also influenced by whether its location is on a sunny or shady side of the building, or whether the stone or brick it’s inhabiting is particularly porous.

Field observations have shown that the fluctuation in the height of the “algal front” is no more than 2 cm (7/10ths of an inch).

So all is well? Not really. One factor the Venetian engineers of 1440 didn’t have to deal with was “motondoso” — that’s a polite way of saying “water constantly splattering from the waves caused by motorboats.”

I’ll be devoting plenty of attention to motondoso on a future page, but I recommend that you draw conclusions very carefully about water level based solely on the line of algae. It’s highly likely that whatever spot you’re looking at is getting drenched by waves day and night, encouraging algae in an extravagant way, something that wasn’t happening back when they were busy carving “C’s” all over town.

The constant and extreme "motondoso" in the Giudecca Canal has created the perfect environment for algae on what used to be considered dry land. Do not ever step on this kind of algae, it's more slippery than a slice of raw bacon. — The constant and extreme "motondoso" in the Giudecca Canal has created the perfect environment for algae on what used to be considered dry land, so its presence here doesn't tell you anything useful about average sea level. Do not ever step on this kind of algae, it's more slippery than a slice of raw bacon.

The Daily Trivia: Regular measurements with instruments began in the 1870s. In 2004, mean sea level was found to be 25 cm (9 inches) higher than it was in 1897. Yet all water-level measurements continue to be based on the mean sea level in 1897.

We like to cling to the old ways here. Or something.

Welcome to the neighborhood

August 12, 2009 6 Comments

Via Garibaldi used to be a canal, which you can tell by the white stone border on each side. It contains everything needful for human life, including two pharmacies. The fact that they both stay in business tells me something about the neighborhood but I'm not sure what.

If someone in Venice were to ask me where I live, the generic answer would be “Castello,” which is the name of the sestiere, or one of the six neighborhoods into which Venice is divided. But that’s just a little too generic, considering that Castello is fairly large and has several hundred little subsets with all sorts of variations ranging from the sublime to the moderately mystifying.

The more precise answer is “Via Garibaldi.” We don’t actually live right there — we’re down beyond the end of it. But it’s an answer which represents not only geographical coordinates and a zip code, but an entire biosphere of its own with its own history and climate and fauna, a zone which to Venetians of other sestieri still connotes verging on the exotic, even vaguely hazardous.

Carnival means the street is clogged with kids, the only difference from every day is that they're in costume. Otherwise, it's just craziness as usual. — Carnival means the street is clogged with kids, the only difference from every other day being that they're in costume. Otherwise, it's just chaos as usual.

Once, when we were living in Dorsoduro, we overheard a mother snapping at her kid: “Stop shouting! You sound just like somebody from Castello!” And when we moved away — to Castello, of all places — Lino could hardly believe how far down in the world he had come. To his relatives, he might as well have gone to Tasmania. In fact, Tasmania would have made some sense. But Castello?

Many, if not most, people who visit Venice think of the city of palaces and monuments, and maybe also some trendy boutiques and clever little galleries. Our part of Venice is a gristly precinct beyond and behind the Arsenal. The Arsenal was the shipyard where Venice’s fleets were built, the foundation on which Venetian power — economic, military, political — rested. It’s thanks to the Arsenal that all those palaces and monuments exist, so Castello doesn’t have to apologize to anyone if it has chosen to remain in its primordial state. During Venice’s Great Days there were as many as 10,000 people working in the Arsenal, and their dwellings and relatives surrounding it constituted what amounted to a company town. Although very few, if any, locals still work in the Arsenal, I’m convinced there are people here who still haven’t discovered fire.

A member opens the clubhouse of the Mutual Aid Society of Carpenters and Caulkers, a flourishing remnant of the old Arsenal days when the workers had only each other to turn to for help.

If Venice isn’t a place for everybody, Castello is even less so. And Via Garibaldi is the axis of a Hogarthian world where the men’s bodies swarm with tattoos; where men and women alike use hand-hewn phrases which can’t be translated and shouldn’t be repeated, and their rampant children have two basic ways of communicating: Yelling and crying. They’re a lot like London’s East Enders (denizens of another once-great seaport enclave) — tough, practical, unromantic yet sentimental homebodies to whom family and neighborhood are the universe, where grown men call each other “love” and women call each other “girls.” It’s not that they don’t know there’s a world out there, they just don’t find it all that interesting.

I love Venice in a complicated way that I don’t understand very well. In the midst of the obvious beauty and grandeur and all, the city is also composed of so many aspects which verge on ugliness but which, strangely, also have their own sort of allure. Nelson Algren once wrote that “It isn’t hard to love a town for its greater and lesser towers … but you never truly love it till you can love its alleys too.” You discover this in unexpected moments and glimpses, where she doesn’t mind you seeing her without her girdle: no excuses, no apologies.

The “alleys” would be out here, with the ingenious, illegal, improvised sewer outflows, and the “What, me worry?” deposits of dog poop and the hand-lettered signs vilifying the anonymous neighbor who has left his bag of garbage under your window, and the mismatched lifelong friends in the bar shouting at each other — the one who’s right and the one who’s wrong — about something that happened years ago. In fact, they’re both right. Or wrong.

What happens is this: People put out plastic bags of garbage long before the collection is due to begin. Sometimes they do this on a Saturday afternoon, which means the bags will sit there till Monday morning. This time frame gives the seagulls plenty of time to bust open the bags and scavenge. Now the pigeons have started to take up the habit. Everyone knows this, including the people who put out their bags, bags which would be collected from their very own doorstep, but which they prefer to bring secretly to this anonymous corner. It's so stupid it's almost beautiful. — What happens is this: Some people put out plastic bags of garbage long before the collection is due to begin.

It's so stupid it's almost beautiful.

This is not nostalgie de la boue; many things about life down here in the bilges range from infuriating to only slightly flinch-worthy. Then there are the aspects you can’t easily categorize — say, the septic tank somewhere on the other side of our canal which for far too long desperately needed pumping out. When we had company for dinner I used to pray that the wind wouldn’t shift. They say you can get used to anything, but I’m here to tell you: Not that.

I was walking down the via Garibaldi one early evening; there was a middle-aged Venetian couple coming toward me.

There had been a few airplane crashes that month: One in the sea just outside Palermo, another that hit near Athens, now one in Venezuela somewhere.

Anyway, I reach earshot just as the woman is saying to her husband, “Not me. I’ll never go on an airplane. Forget it.”

He says, “What about a ship?”

“Not even a ship. I’m staying home, I’m not going anywhere. If I die, I’m going to die right here in Via Garibaldi.” (Wait a minute — “If” you die?).

That’s what the true voice of a neighborhood sounds like — especially this one. Via Garibaldi to the bitter end.

I’m with her.

You'll always run into somebody to talk to -- or about -- on Via Garibaldi.

Food, History

Street Names: Refreshing

August 11, 2009 2 Comments

There are four places in Venice which share a mystic link, which is discernible only to the initiated. The initiation will now proceed:

The "'Passage Under a House' of the Waters"

The “waters” in this street name are not those of the adjoining canal, you may be glad to know.

They were the delightful iced drinks which were sold in shops often called botteghe da acque, or “shops of the waters.” Such a shop was doing great business here in 1566, run by a pair of brothers, Alvise and Girolamo Giusto.

In 1724, a guidebook stated that “The best chocolate, coffee, refreshing frozen waters, and other such drinks are made and sold in the Calle delle Acque, near the Ponte dei Baratteri.” Right here, in other words.

These places were not unlike the cafes we know today; they were often small, crowded, loud, and attractive to gamblers. (There are still assorted joints around town where little old men sit all day playing cards and shouting at each other, but their drinks usually involve some kind of alcohol, and it’s not particularly frozen, either.) On November 10, 1756 a decree forbade gambling in this very locale, which leads me to suspect that things had gotten even further out of hand than was usual.

Frozen beverages require ice, which was made and sold in various places around the city. Older Venetians have no trouble remembering the boats loaded with large blocks of ice, which the men who rowed the boats would haul ashore wrapped in sheets of coarse hemp to whatever customer had ordered it. The block went into the refrigerator — in America it was simply called an icebox — where it kept the food cold (or cool, anyway) until it had melted away, dripping into the pan below.

In 1661, when this street was mentioned in a property document, the sale of ice was a semi-monopoly of the coffee business. This is not surprising, considering that the coffee-house was where the iced drinks were made.

While we’re discussing potables, you also had the option of something stronger, particularly grappa and its relatives, distilled liquids near which one should not play with matches.

The spelling of this street name is a bit eccentric; it ought to be acquavite, or “water of the vine,” as grappa and some of its relatives are made by distilling either wine or grape residue (vine, stems, seeds, skins, etc.), while aquavit is made from grain. But as the word has also been transmogrified into acqua vitae, or “water of life” (“life” being “vita“), we won’t quibble. I guess they know how to name their own streets.

And who had the concession to sell these shots of liquid fire? The coffee-house owners again. In 1711, in the street above, near the church of the Gesuiti, there was just such an establishment being run by a certain Elia Giannazzi. By 1773 there were 218 shops in Venice specializing in acquavite. Life was hard, winter was long, it kept you going.

A very Venetian product which Giannazzi and his confreres would also have sold was rosolio. Still made today in various forms, it is a liqueur made of rose petals which is often used as a base for other liqueurs. I’m not sure what would happen if you asked for rosolio in a cafe or bar today; you’d probably have better luck asking for one of its siblings, such as limoncello or maraschino.

A note on alcohol: You will frequently read that alcoholism is hardly known in Italy because wine is such an integral part of the culinary and social culture. Children start sipping wine at an early age, at meals, and so it is assumed that they are immune to excess. However, these cliches do not acknowledge the popularity and omnipresence of what are generally termed super-alcoolici, or hard liquor, especially with people living along Italy’s northern rim where mountain traditions often involve making and consuming highly inflammable liquids.

Young people today in Italy may or may not drink wine with their meals, but increasing numbers of them will almost certainly be binge-drinking hard liquor in discos and bars on the weekend and then attempting to drive home. In Venice, this often means using a motorboat, probably without any lights on, usually at high speed. More often than you’d wish, you read about some adolescent who never made it because he “painted himself on a piling,” as they say here. Or dying by alcohol poisoning. And in case you’re tempted to similarly romanticize the seemingly so-grown-up approach to alcohol in France , which like Italy shares the stereotpical image of the jovial family, children included, tranquilly drinking wine out in the garden with their baguettes and challenging cheeses and all, I merely note that France has the highest rate of alcoholism in the world. So, easy with the cliches, here as everywhere. Nothing is simple.

And so we come to the fountainhead of all these concoctions: The cafetier, who sold and prepared coffee to be consumed on the spot and who, as we have seen, had his finger in the ice and booze businesses as well.

Coffee has a long and glorious history in Venice; Venetian merchants first recorded its use in Turkey in 1585, and began to sell it in Venice in 1638, whence the enthusiasm for coffee-houses spread across Europe. The Caffe Florian in the Piazza San Marco opened on December 29, 1720, and makes a good case for being the oldest coffee house in continuous operation.

The “mystic link” I mentioned above is therefore revealed to be coffee. The coffee-house owners and/or operators managed a very large slice of the liquid refreshment business in Venice, and while Venetian coffee doesn’t enjoy the fame of its Neapolitan or Roman cousins, I’m willing to call it the water of life. Especially first thing in the morning.
