This check dam design tool helps you to design a check dam. It shows an example of a longitudinal view of a check dam section in a catchment. Each check dam needs a design accordingly to its location. Therefore, after you have decided on a perfect spot with suitable local building material, you need to calculate the specific dam measurements. Click the green buttons and a manual will pop up. They specify the calculation of certain values such as the size (height, length, width) of a check dam or the distance between check dams.
