LiveDijk De Veenderij

Dijk breaches are often caused by high water levels. Dikes become saturated with water, which can cause them to shift or collapse. The situation is different for peat dikes. Here, the problem is caused by long-term drought. Dry peat is light and adheres weakly to the base. That can quickly result in a dike shifting. Drought is therefore a serious problem for the peat dikes in the Netherlands. The floods in Wilnis and Terbregge in 2003 were caused by a failing peat dike during a dry summer. Efforts were made to measure the effects of drought at a peat bank, ‘de Veendijk’, to the south of Amsterdam. The experiment could help us to find a good way of better assessing the risks during drought periods. The test started in the autumn of 2011 and the results were completed early 2013. The reports are in Dutch, see below.
