Background

Integrating CWMS models (including HEC-HMS, HEC-ResSim, and HEC-RAS) into a watershed using the CAVI is a relatively easy and sequential process that begins with importing the individual models into the watershed. The remaining steps involve creating MetVue alternatives to provide meteorological inputs to HEC-HMS, creating CAVI forecast runs that connect desired sequence of computes of the individual model alternatives, establishing data linking for the models, and setting up extract lists.

In this workshop, you are provided with a starting foundation for the Russian River watershed that includes background maps, already configured time series icons, and scripts for downloading real-time data. You are also provided with individual models as your import sources. You are tasked with completing the watershed's model integration (focusing on the HEC-MetVue, HEC-HMS, HEC-ResSim, and HEC-RAS models) and generating a successful test forecast simulation.

Tasks

  1. Open the Integration_Workshop_HEC_RR watershed in Local mode.
  2. The individual models are ready for import here:

    C:\CWMS_Class\Models4Importing


  3. From the Setup tab's Watershed Panel
    1. Import the HEC-ResSim model
      1. Choose importing the Watershed instead of an Alternative.
    2. Import the HEC-MetVue model.
      1. Open the MetVue plugin and make sure to set the RussianSubbasins shapefile as a basin average map and Save the Project.  Making the Basin Average Map setting at the Project Defaults level will get inherited to all the Sessions and Map Windows. As shown in the figure below, the RussianSubbasins.shp shapefile has been set as a basin average map (see the green icon in the tree). If your icon is not green, then right click on the RussianRiver.shp node and select Make Basin Average map.

    3. Import the HEC-HMS model.
    4. Import the HEC-RAS model.
      1. The CAVI "Import" feature for HEC-RAS does not copy all the required files or set up RAS Mapper. Copy the _Data folder from the Models4Importing/HEC-RAS/Russian_River_Class folder to the watershed/Integration_Workshop_HEC_RR/ras folder.
      2. Make sure that RAS Mapper is set up correctly in the watershed, with the terrain mapped and the projection set.
    5. Finish setup of the HEC-MetVue alternative:
      1. Using the steps in the PowerPoint below: Completely set up the QPF Alternative using the 1 hour grids available at C:\CWMS_Class\dated\db\grid
         

  4. From the Setup tab's Models menu:

    1. Assign Model Alternative Keys, for example:
      1. MetVue– QPF (Q)
      2. HMS – Daily Forecasting-1HR (C)
      3. ResSim – RT-Normal (C)
      4. RAS – Russian River Real-Time (U)
    2. Create a Forecast Run that connects:
      1. Your new HEC-MetVue Alternative
      2. The 1hour HEC-HMS Alternative
      3. The HEC-ResSim Alternative that has the normal operations "RT-Normal"
      4. The HEC-RAS Alternative for Real-Time.
    3. Complete the model linking in the Model Linking Editor.
      1. Make sure to toggle the Input From selection of MetVue gridded inputs to HEC-HMS. Double-check the tool tip has the expected record pathname from the HEC-MetVue alternative.

      2. Make sure to set all of HEC-ResSim's Known Flow linkages to get Input From the HEC-HMS model alternative. 
    4. Create the Extract List:
      1. Create and complete a group for Observed Time Series.
        1. When creating this extract group, make sure to add an offset of -8 Hours to the extract start time. That will ensure the the CDEC data will cover the time period needed for the forecast run within the watershed.
        2. After adding the times series available from the Required Input panel, inspect the list of parameters. If missing the required reservoir elevations, use the Add Extract Data Set... button to browse to the Russian_TimeSeries.dss database file and add the elevation records to the extract list.

      2. Create and complete an Extract Group for Cumulus Precip Grids 
      3. Create and complete an Extract Group for Cumulus Temperature Grids. 

  5. From the Modeling tab, create a new forecast using the time window below. 

    Forecast Time: 04Jan2024 1000
    Extract Start: 01Jan2024 1000
    Start Time: 01Jan2024 1000
    End Time: 07Jan2024 1000

  6. Compute the Forecast.


Were you able to successfully compute the forecast? If not, what happened and how were you able to fix it? Once the forecast successfully computes, you have completed this workshop.
