TR-55 models can be defined in WMS using the commands in the TR-55 menu and resulting dialogs. The TR-55 model has long been used to determine the increase in runoff resulting from the development of rural land into urban land. The WMS interface to TR-55, combined with the basin delineation and time of concentration calculations from feature objects (see Lag Time and Time of Concentration), makes it simple to set up and run several different scenarios in a relatively short time period.

This chapter describes the mechanics of the WMS interface to TR-55 and is not a complete reference to the methodology, uses, and limitations. For more in depth information you should read “Technical Release 55: Urban Hydrology for Small Watersheds, 2nd Edition.”

Initialize Simulation

The first time you open the TR-55 simulation dialog (no matter whether you have a basin, an outlet, or nothing selected) the only option available in the TR-55 dialog is the Initialize TR-55 Data button. In order to allocate memory in WMS for TR-55 variables you must initialize the data once. Should you decide to work with a different model you may want to choose the Delete TR-55 Data button. If you are planning on using a TIN, DEM, or feature objects to delineate and compute watershed parameters you should initialize TR-55 data first so that computed parameters can be stored in the TR-55 data structures.

Copying Results to the Clipboard

The Copy to Clipboard button can be used to copy the information from the TR-55 data window to the clipboard for pasting into a word processing document. The data window display options determine which things are visible and ultimately copied to the clipboard.
