WMS:MODRAT Edit Parameters

Attributes or parameters for all MODRAT hydrograph stations are defined and/or edited using the Edit MODRAT Parameters dialog, shown below. This dialog is accessed by selecting the Edit MODRAT Parameters command from the MODRAT menu or by double-clicking on a basin, reach, or relief drain when MODRAT is the active model in WMS.

If a subarea, reach, or relief drain is selected before issuing the Edit MODRAT Parameters command, then the data for that object is loaded for editing. When a hydrograph station is selected (subarea/reach/relief drain), only the items which correspond to the selected hydrograph station are active, all others are inactive. For example, when a subarea is selected, all items under the Basin Data heading are active and all items under the Reach Data heading are inactive.

Once the Edit MODRAT Parameters dialog appears, it will remain open until the user selects the Done button. This enables the user to switch between basins, reaches, or relief drains quickly and define the necessary parameters without closing and opening the dialog for each hydrograph unit.

Lateral

The letter entered in the Lateral field of the MODRAT Parameters dialog indicates the line to which the subarea or reach is connected. The main line in any MODRAT model is line A; laterals may be labeled B through Z. Reaches with two letters indicate a confluence point of two or more reaches. The lateral assignment is generally done automatically in WMS; for more information on lettering your watershed model, see the MODRAT Numbering the Tree section.
