Water War Games
In 1952, the Dutch built a chain of weirs, sluices, dykes and bunkers to divert waters from the Rhine river and flood an area 126 kilometres long and 5 kilometres wide…. to thwart a possible attack by the Russian army (the Cold War was still on). And this ‘waterline’ was not the first one the Dutch had built; they had been at it since the 17th century!
In the late 1980s, irrigation and drainage systems were constructed in Pakistan as part of the SCARP-6 project. Many structures had dual purposes. Evaporation ponds, for example, were built in the middle of the desert to reduce water logging AND as a permanent obstacle for the Indian army. At strategic locations, bridges built across drains were designed to be just wide enough to let Pakistani tanks pass through but too narrow for the larger Indian tanks.
The latest post on TheWaterBlog (‘Water War Games’) details these examples of infrastructure developed to manage water… and for defence purposes. Do you know of more? Please share by responding to this email, or by commenting below the post.
