As regions are selected in the Regions overlapped by watershed window the relevant parameters for the regional equations are added to the spreadsheet. Parameters that can be computed by WMS are defaulted to their computed values at the time the regression equation is selected for use. A user may override defaulted values and later return to the computed values by clicking on the Restore Computed Geometric Values button.
Parameters not computed by WMS when computing basin data can sometimes be computed using the generic GIS Overlay calculator. This option (under the Calculators menu) can be used for example to determine the percentage of lake or forest cover from the drainage coverage and a land use layer.
The NSS program includes in its database the range of parameter values for the watersheds used in developing the regression equations. The applicable range, along with the expected units are displayed on the same row as the parameter edit field.
