WMS:HEC-HMS Job Control

The HMS Job Control dialog is where parameters for the HMS model run can be set. All the HMS data is entered using one of three tabs in the HMS Job Control dialog . These tabs are meant to correspond to the three different types of data entered in HMS: the HMS meteorologic data, the control data, and the basin data.

The dialog is reached through the HEC-HMS | Job Control menu command.

Control Options

The control option data entered in WMS is exported to the HMS project and used to set the appropriate HMS parameters when reading the project into HMS. After reading the project into HMS, the data entered in the Control Options tab shows up in the Control Specifications of the HMS model. The data included in the basin model include the name, description, and the other items in the Control Options tab shown below:
