The adverse slopes in GSSHA

Recommended Posts

Hello,

Is there any way to check the adverse slopes instead of the visual inspection as there may be a very small tributary that can't be seen. Best regards

One way to check for adverse slopes is in the GSSHA model checker.  This can be accessed by selecting the Model Check command in the GSSHA menu (2D Grid Module).  Your streams all need to be defined as trapezoidal or cross section channels and you need to have Diffusive Wave routing turned on in the GSSHA job control for the model checker to find streams with adverse slopes.
