First, go to “Step 1” and fill the channel’s width and depth. Automatically, the sheet will calculate some necessary parameters, such as wetted perimeter, hydraulic radius and others. Then, go to “Step 2” and fill the values in the green cells. There are two useful tables that will help you filling the Manning’s parameter, as well as the dynamic viscosity of water. If you have successfully filled the input values, the sheet will calculate the desired flow values (discharge, velocity and type of flow).
