trying to run a pure 2D model with some steep terrain, 1:1, using QT and HQ boundaries. As expected we are getting high instabilities at this change in elevation. typically we could overcome this using rainfall on grid, however in this instance, the client prefers hydrograph. has anyone modelled steep terrain with QT and HQ boundaries? can anyone suggest a method to override, overcome these instabilities?
