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.
