As a result of the ongoing drought, there is an average rainfall deficit of 250 l/m² in our region. Twice the average amount of rainfall would be required during the next 3 months in order to make up for the deficit.
Due to the drought, water levels in many Flemish canals and rivers are too low. The Leuven University (KU Leuven hydrologist Patrick Willems says that “The biggest issues can be averted if it starts raining during the coming week”. The Albert Canal between Liège and Antwerp and the Ghent (East Flanders) to Terneuzen Canal are giving particular cause for concern.
“The water supply from the Meuse and the Scheldt and Leie basins is declining, but if it rains next week, it should be just sufficient to avoid major issues”, Patrick Willems says.
The canals are important for inland shipping and for industry that uses their water. Furthermore, the Albert Canal accounts for 40% of the drinking water consumed in Flanders. Earlier this summer weight restrictions for freight traffic on larger ships were introduced on the Ghent-Terneuzen Canal.
Impact on nature
During the 3 months from 1 May to 31 July there was around a third less rainfall than normal in Belgium. This followed a historic dry spell in March and April. Last week, there was another heatwave, the second of the summer.
Nature is struggling to cope with the drought. For example, trees are already beginning to lose their leaves due to the dry conditions.
