HydroGeoSphere/Surface Flow (Properties)
Default surface flow values edit
Unless you modify the default values, all zones (and elements) in the surface flow domain will be assigned the default properties listed in Table 5.18:
Parameter | Value | Unit |
---|---|---|
Name | Surface flow defaults | - |
X friction factor | 0.0548 | - |
Y friction factor | 0.0548 | - |
Rill storage height | 0.0 | m |
Obstruction storage height | 0.0 | m |
Node coupling scheme | shared | - |
Coupling length | 1 × 10−4 | m |
For each instruction we will again indicate its scope (i.e. .grok, .oprops). Recall that if an instruction is used in the prefix.grok file, it will affect the current set of chosen zones, while in a properties (e.g. .oprops) file, it will only affect the named material of which it is a part.
