Shear Stress Calculation - Spillway
Shear Stress Calculation - Spillway
(OP)
I am looking at alternative linings (other than riprap) for an auxiliary spillway for a small embankment dam. I am thinking along the lines of a vegetated TRM. As a first look, I calculate the velocity and shear stress in the downstream section of the spillway to use as a guide for selecting a lining. For the spillway section across the embankment, however, the slope is zero, and as I understand it the shear stress would be zero by definition. Is this right or am I misguided here?

www.wcc.nrcs.usda.gov and then go to Hand H and Tools.
Sites is a decent routing program, but can be used to predict spillway stability for vegetated earth and rock spillways. It can be a pain to use, but can give you some idea of expected damage from different flow events.
