When modeling water temperature, each water quality cell must be associated with a meteorological dataset. When modeling water temperature, the geometry dataset must be linked to a meteorological dataset (refer to Chapter 3). The meteorological dataset is used by the geometry dataset to assign each reach and reservoir to a met station in the linked meteorological dataset. When linked to a meteorological dataset, each water cell (defined in the geometry dataset, see Section 4.3) in the water quality model is individually assigned to a particular met station in the meteorological dataset.
The Met Stations tab (Figure 4.45), in the Geometry Editor (Figure 4.14), contains a table providing a list of the HEC-ResSim reaches and reservoirs in the geometry extent and a column of dropdown lists for selecting the best meteorological station. The Met Stations dropdown lists do not populate until a meteorological dataset is selected from the Met Dataset (Figure 4.45) dropdown list. Completing the Met Stations tab (Figure 4.45) is only required when modeling water temperature.
Section 4.9.1 provides instructions for completing the Met Stations tab (Figure 4.45), in the Geometry Editor (Figure 4.14).
