Figure 1. The MD_SWMS GUI tool shown with an application of the Kootenai River, Idaho. The GUI features menus, toolbars, treeview of data objects loaded into the project, graphics view with tools for zooming and panning, status bar and probe bar for dynamic feedback of data values. The main panel of the application shows a portion of a 10-kilometer reach of the Kootenai River with a model prediction of velocity overlain on a georeferenced digital orthoquad. A detail (inset) of the solution shows the complicated flow pattern in a sharp bend of the river. Velocity magnitude is shown by color and velocity vectors are shown in black.
