Cesky Krumlov Floods 2013

Did they say the flood reduction works would stop a once in a century sized flood?  This argument was used to justify the destruction of Cesky Krumlov's historic riverside and island, the grubbing out of a channel creating a speeding river where once had been a slow one, and the replacement of soft river banks with man-made concrete and granite walls. Well on Sunday the reduction works experienced their first test and failed.

In 2002 Cesky Krumlov and Prague suffered devastating floods as waters released from Lake Lipno rushed up the Vltava. This time the cause was different - we have had unseasonably wet weather last month which meant the ground was saturated when on Saturday the heavens opened for a massive downpour which lasted over 36 hours.

The water having nowhere to go ran off the fields into the streams turning them into torrrents and from there the waters poured downhill into the waiting River Vltava.
Residents in Cesky Krumlov's riverside properties were woken around midnight to sirens and the warning that the flood was on its way. The floods not only hit the area along the Vltava, but also along the little rivers and streams. As we drove into Cesky Krumlov the following morning along the Chvalsinska Road, we could see that a small stream had turned into a monster and swept across the road, flooding properties and car parks. A white car lay crushed against a fence. 

By the time we arrived in Krumlov historic centre the flood levels had already dropped 1.5 metres, but the sight was still impressive. We went to Laibon Restaurant on Parkan, which was open despite having been under 10 cms water earlier that morning. Life goes on, as it has done after countless floods over the centuries.

The truth is that no flood reduction work could ever be fully successful in Cesky Krumlov. Floods have been a way of life in this town and without raising the town by several metres they will remain so. The reduction measures have even had a disastrous consequence, which was foreseen by the former civic engineer Mr Pesek, namely the walls of the houses in Parkan are showing large cracks, due to the drying out of their foundations. Let's hope the Town Council doesn't see this as an opportunity to throw more money at failing to address the floods and so ruin this lovely town.

Flood Control and Willows

The Town Council is arguing that the way to control floods in Cesky Krumlov is to cut down the willows and to remove the natural banks on which they stand with concrete walls. There are several arguments against their plans - a) the aesthetic one, most of the time the river is low and the concrete will look awful, especially in this UNESCO heritage site, b) the heritage one, they are destroying an island which has been around for centuries, c) wildlife - the island is home to nesting birds and even occasionally plays host to otters. But I for one am not convinced that what they are proposing is the best way to control flooding either.

The key thing to note is that flooding is not common in Cesky Krumlov - in fact they are planning for a 100 year flood event. How can such a rare event justify such vandalism? Now as it happens flooding is common in Gloucestershire (my English home), indeed it is pretty common in Britain fullstop. In the UK we have rather moved away from constantly resorting to concrete walls, preferring to "focus on ways that work with nature, not against it" (in the words of the UK Government). Part of that strategy is the use of willows and other riverside trees to bind the river banks. There has been some fascinating approaches which create riverwalls from living woven willow (example shown above).

Equally important is to address the cause of the flooding rather than the flood. Locally the general view is that the last big flood was caused by someone opening the sluices on Lake Lipno and releasing a huge amount of water into the River Vltava, which swept down and flooded the towns, such as Cesky Krumlov, along its banks. The simple answer would then appear to be, don't open the sluice gates like that!

If you want to help the protest you can do two things - 1/email the Town Hall (addressed to the Mayor, Ing. Luboš Jedlička) c/o Bozena.Kaliskova@mu.ckrumlov.cz adding your name in support of the petition of March 2009 that asks for the retaining of the small island under Lazebnicky bridge
2/ write to UNESCO and ask whether they are aware of this situation, the citizens' protests, and the extent of damage the projected works may cause. The name and contact details are:wh-info@unesco.org

Floods

The first time we visited Cesky Krumlov was after the terrible floods of 2002. On our first night our friends gave us a tour of the town - it went something like this: " You see that line on the plaster of the house, that is where the flood water rose to."... "The water came down there and right up here." It was almost amusing the way the flood, "the worst in 1000 years" (although I am not sure who was measuring the water height in 1002) kept creeping into the tour of this most beautiful of towns. The floods clearly did huge damage and it has taken years to restore all the buildings. Like my friends, when giving a town tour to visitors, I find myself pointing out the flood line.

But I never really understood why the flood made such an impression on my friends, until now. In the last few days floods have torn through my beloved Gloucestershire. Even Winchcombe, the little Cotswold town of my birth, was hit by almost tidal waters as they swept off the hills and, channelled into the corner of Winchcombe's steep valley, tore through the streets and tore down dry-stone walls, flinging the stones around like pebbles. As a girl I was confirmed in the great Norman abbey of Tewkesbury, where as I write the flood waters have broken through into foundations and vaults. It was this news more than any other that brought tears to my eyes. The abbey normally stands above Tewkesbury's regular floods, its ancient builders (building yes just under 1000 years ago) had known how and where to place this holy site. Somehow therefore it is the waters' disregard for the old and the wonderful that hurts more than anything.
