3.3 Common Parameters

Some parameters are available for all or most of the hydrologic objects. These parameters are given in Table 3-2.

Parameter Name Description Default Value Applicable Hydrologic Object
NHYD Hydrograph number Next available number ALL
NAME A descriptive name Hydrograph object type name and NHYD ALL
COMMENTS 1 Any text description Empty ALL
COMMENTS 2 Any text description Empty ALL
COMMENTS 3 Any text description Empty ALL
OUTLET The NHYD of downstream hydrologic object Empty ALL except ShiftHyd and DuHyd
DWF A constant Dry Weather Flow or baseflow (m³/s or ft³/s) 0 All flow generation hydrologic objects
DT Simulation time step increment (min). 5 ALL except AddHyd, ShiftHyd, DiverHyd, DuHyd and ReadHyd

STORM INDEX The index of the rainfall in the rain group 1 All flow generation hydrologic objects
RAIN Optional list of rainfall intersities (mm/hr or in/hr) entered at the time steps equals to DT. If the list is not given, the model will use the rainfall data assigned by STORM INDEX. Empty All flow generation hydrologic objects
