DuHyd is used to separate the major (street flow) and the minor (pipe flow) hydrographs from a total hydrograph.
TABLE 3-8 DUHYD PARAMETERS
|Parameter Name||Description||Default Value|
|Major||NHYD of major system connection||Empty|
|Minor||NHYD of minor system connection||Empty|
|CINLET||The peak flow capture rate per inlet (m³/s or ft³/s)||0.06|
|NINLET||The number of inlets in the drainage system which have the capture rate of CINLET. Note: The maximum minor system capture equals CINLET × NINLET.||10|
