ABSTRACT: Weir pools are one of the most widespread artificial aquatic environments in Europe. In recent years, they draw the attention of scientists and managers, who try to understand how they work and put in place strategies to manage them. However, these studies confront with the difficulty of delimiting the spatial extension of weir pools: to solve this problem, we created a direct technique that permits to identify their perimeter through the measure of the raising of the waterline and the slowing down of the flow generated by weirs. To verify its validity and efficiency we tested it in two weir pools located in France to check whether it can find them. In both cases, the results obtained are convincing and they demonstrate how this methodology can be used to study and manage the spaces that form upstream weirs.


Keywords: Weir, Weir pool, Run-of-river dam, Weir pool perimeter.
