SHIFT HYDROGRAPH A simple translation of the hydrograph. Does not attenuate the peak discharge. LOW
ROUTE CHANNEL Combines the three routing commands of HYMO into a single command, based on the hydro-logic method VSC (Variable Storage Coefficient). MEDIUM
ROUTE MUSKCUNGE Applies the Muskingum-Cunge method of routing, which is based on the continuity equation and the storage- discharge relation. HIGH
ROUTE PIPE Applies the VSC method for conduits, and gives the minimum size to avoid surcharge. MEDIUM
