except that the Met Segment name in the ‘Add Met Segment’ form may be chosen from a drop-down list. The precipitation data set defines the met segment and thus may not be edited in the Edit Met Segment form.
The eight constituents listed in the first column of the grid constitute a full set of data for a met segment. The next three columns contain drop-down listboxes with all available selections for each column. These columns should be filled out left to right because each successive field is dependent on the previous. The WDM ID column lists the WDM files used by this project (there may be up to 4). The TSTYPE column lists the types of time series available for the selected WDM file. The DSN column lists the data set numbers of the time series available for the selected WDM file and time series type. A real number should be typed in for the final 2 columns, which contain multiplication factors to be applied to the PERLND/IMPLND operations and to the RCHRES operations.
