To create a new meteorological dataset:

  1. From the HEC-ResSim main window, from the Water Quality module (Figure 3.1), from the Water Quality menu (Figure 3.2), click Meteorological Data. The Meteorological Dataset Editor (Figure 3.3) opens.


  1. From the Meteorological Dataset Editor (Figure 3.16), from the Met Dataset menu (Figure 3.4), click the New menu command. The Create New Meteorological Dataset dialog (Figure 3.17) opens.


  1. From the Create New Meteorological Dataset dialog, enter a name in the Name field (e.g., Met_Dataset1 in Figure 3.18) and a description (optional, but recommended) in the Description field (Figure 3.18).



Figure 3.17 – Create New Meteorological Dataset Dialog Box

  1. Below the Description are two selector panels that lists all the available (Inactive Met Stations panel) and selected (Active Met Stations panel) met stations (Figure 3.17). The met stations are listed in alpha-numeric order in the selector panels.


By default the Active Met Stations panel contains all met stations in the watershed (e.g., Dry Ck Mouth, DryCk_10, Lake Mendocino Outflow, MCk_DCk, Sanel Valley, Windsor Gage, Yoakim Bridge in Figure 3.17). Use the selector panels to select the met stations that are active or inactive for the new or edited Meteorological Dataset.

  1. From the Active Met Stations (Figure 3.18), select the locations to remove from the active list and add to the inactive list, and click Remove (Figure 3.18) to set the locations as Inactive Met Stations for the created meteorological dataset.


  1. Click OK to close the Create New Meteorological Dataset dialog (Figure 3.18) and save the new meteorological dataset. The created dataset is added to the met dataset navigation bar in the Meteorological Dataset Editor (Figure 3.16).


  1. If the user sets all stations as inactive (e.g., clicks the Remove All button Figure 3.18) and clicks OK, then a Warning message dialog opens (Figure 3.6). Each meteorological dataset must have at least one active met station. From the Warning message dialog, click OK (Figure 3.6), and from to the Create New Meteorological Dataset dialog (Figure 3.18) add at least one station to the Active Met Stations (Figure 3.18) list, and click OK.

  1. The Create New Meteorological Dataset dialog (Figure 3.18) checks if the Meteorological Dataset has a unique name. If the name already exists when the OK button is clicked, then a Warning message dialog opens (Figure 3.19) stating that the user must enter a unique name for the Meteorological Dataset. From the Warning message dialog, click OK (Figure 3.19), and then, from to the Create New Meteorological Dataset dialog (Figure 3.18), enter a unique name in the Name (Figure 3.18) box and click OK.

  1. The Create New Meteorological Dataset dialog (Figure 3.18) closes, and the created dataset is added to the met dataset navigation bar in the Meteorological Dataset Editor (Figure 3.16). Also, the created meteorological dataset opens in the map window schematic in the HEC-ResSim main window (Figure 3.1). In other words, from the module data, from the Met Dataset dropdown (Figure 3.1), the created dataset is automatically selected (e.g., Met_Dataset1 selected in Figure 3.1). Click OK to close the Meteorological Dataset Editor (Figure 3.16), or begin to define the meteorological input data (see Section 3.5).
