WMS:Hydrologic Computations

HY8 Modeling Wizard showing the Hydrologic Computations step.

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

Help

Compute GIS Attributes – Depending on the model you are using, this button brings up a dialog allowing you to compute attributes from your land use and/or soil type data.

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

Edit Parameters – This button brings up the edit parameters dialog for your model, allowing you to change modeling parameters for all the sub-basins in your watershed.
