The Watershed menu is shown below. The first section of commands
are for watershed analysis and are primarily based on TR-55. These
commands are arranged in the order that they would be applied. The
first commands calculate the watershed boundary. Using the
watershed area and land use types, the curve number can be
calculated, which leads to time of concentration and hydrographs.
Then the peak flow can be calculated. The second section of
commands are for hydrograph routing using TR-20. The bottom section
has commands for linking to SEDCAD, HEC-RAS and HEC-2.
