Induced meandering through one rock dams

This summer, we experimented a new low tech solution to contribute to the rehydration our dry Alentejo landscape. It is inspired by the work of Bill Zeedyk and Van Clothier and their experience with temporary streams. We prepared two trucks of heavy stones, discharged them into a straight segment of our temporary river. The next morning, our quartet of four enthusiasts went up the river, arranging these stones into four little, oblique, five rows "one rock dams" (ORD). The first rains will tell us how successful our test dams will turn out to be... And we'll be curious to see how the bee-eaters will react to it too - see their nest holes below.
