WMS:Hydrologic Computations

HY8 Modeling Wizard showing the Hydrologic Computations step.

The Hydrologic Computations step is used to compute hydrologic parameters for the watershed and sub-basins.

Help

Compute GIS Attributes – Depending on the model being used, this button brings up a dialog where attributes are computed from the land use and/or soil type data.

Travel times – This spreadsheet allows computing the Time of Concentration for all the sub-basins in the watershed using either the basin data or map data method.

Edit Parameters – This button brings up the edit parameters dialog for the model where modeling parameters are changed for all the sub-basins in the watershed.
