After computing an HEC-MetVue model alternative, you can view its output datasets, such as precipitation or temperature, directly within the Modeling map window.

Viewing Results via the Map Window

Before you begin - ensure all lightning bolts are blue, indicating that the results have been computed and are being displayed.

To view gridded output data, expand the tree for the HEC-MetVue model alternative and click on the dataset you want to visualize. The data will appear in the map window, as shown in the figure below.

Understanding the Displayed Results

Both input and output datasets for a HEC-MetVue model alternative can be viewed in the map window.

In the example shown above:

  • Frcst_Precip - The total forecasted precipitation over the forecast period.
  • Frcst_Temp - The average forecasted temperature over the forecast period.
  • Obs_Precip - The total observed precipitation over the lookback period.
  • Obs_Temp - The average observed temperature over the lookback period.
  • PRECIP (M) - The total precipitation over the entire simulation.
  • TEMP (M) - The average temperature over the entire simulation.

HEC-MetVue uses the polygon shapefile defined during model setup to display basin-averaged values for the selected dataset. For instance, if PRECIP is selected, it represents the combined total of observed and forecasted precipitation across the entire simulation period. For example, the basin named Cazadero shows a predicted total of 8.73 inches of rainfall for the entire forecast simulation.

General Notes on Data Display

  • Precipitation: Displayed as total values, averaged across basins for the selected time period.
  • Temperature: Displayed as average values, averaged across basins for the selected time period.
  • Snow Water Equivalent (SWE): Displayed as total values, averaged across basins for the selected time period.

Viewing Results in HEC-MetVue Standalone

You can also view the results in the standalone HEC-MetVue application. Reasons to do this include:

  • Viewing an animation of the precipitation
  • Reviewing individual daily totals using the Zonal Editor (refer to the HEC-MetVue Zonal Editor video for more details)
  • Viewing basin averages for both the lookback and forecast periods
