To assign meteorological stations or edit station assignments for the HEC-ResSim network elements (in the Reach/Reservoir table):

  1. From the Geometry Editor, from the Met Stations tab, from the Met Dataset dropdown list, select the appropriate meteorological dataset (e.g., Met_Dataset1 in Geometry Editor – Met Stations Tab – Example Met Dataset Linkages).
  2. By default, all HEC-ResSim reaches and/or reservoirs in the geometry extent are automatically linked to the nearest meteorological station in the selected met dataset. For the example provided in Geometry Editor – Met Stations Tab – Example Met Dataset LinkagesLake Mendocino is linked to the Sanel Valley met station.
  3. To modify the default met station selection, from the dropdown list in the Met Stations column, select the appropriate met station for the corresponding reach/reservoir. For other cells in the table, repeat the manual met station selection, as necessary. Click the Apply button to save the new linkages.
  4. To reset all met station and reach/reservoir to the default linkages, click the Fill with Nearest button.
  5. Click Apply (Figure 4.46) to save edits. Alternatively, click OK, to save edits and close the Geometry Editor.

To assign meteorological stations or edit station assignments for the ResSim network elements (in the Reach/Reservoir table):

  1. From the Geometry Editor, navigate to the Met Stations tab.
  2. In the Met Dataset dropdown list, select the appropriate meteorological dataset (e.g., Met_Dataset1). This selection links the geometry to the selected meteorological dataset (Geometry Editor – Met Stations Tab – Example Met Dataset Linkages).
  3. By default, all ResSim reaches and/or reservoirs within the water quality geometry domain will be automatically linked to the nearest meteorological station in the selected dataset. For example, as shown in the Geometry Editor – Met Stations Tab – Example Met Dataset Linkages, Lake Mendocino is linked to the Sanel Valley meteorological station.
  4. To modify the default meteorological station selection, click the dropdown list in the Met Stations column for the desired reach or reservoir and select the appropriate meteorological station.
  5. Repeat this process for any other network elements that require a manual selection of a meteorological station.
  6. To save the new linkages, click the Apply button.
  7. If you wish to reset all met station assignments and revert to the default linkages, click the Fill with Nearest button.
  8. After completing your edits, click Apply (Figure 4.46) to save the changes. Alternatively, click OK to save the changes and close the Geometry Editor.



Geometry Editor – Met Stations Tab – Example Met Dataset Linkages
If more than one Met Dataset is set up, ResSim will store the association for each of the meteorological datasets. If specific Met Stations are not assigned to individual reaches or reservoirs, ResSim will use the default method, which selects the nearest meteorological station to the reach or reservoir. This ensures that each reach or reservoir is linked to the appropriate meteorological data for modeling purposes.
