Resource Library acts as the sole source of climate data for model. The climate data (rain, temperature, evaporation, groundwater and flow) can be added to the working model by 1) using the Add to model button/menu, 2) using Add All Design Storms to Project menu or 2) drag-and-drop.

To use the Add to model button/menu:

  1. Select the climate data in the Library Explorer;
  2. Click the Add to Model button in the toolbar or choose the Add to model … menu in the context menu;
  3. The Add Storm(s) to Rain Group window will appear. The first one allows to choose one of the existing rain groups to add the design storm. The second one would create a new rain group with the given name.
  4. Click OK to add the design storm to the model. The new rain group will appear in Project Manager.

To use Add All Design Storms to Project Menu

Design storms in a group can be added to a model at once. To do this, select the group in the Library Explorer and choose the Add All Design Storm to Project from the context menu as shown below. All the design storms will be added to the model and the run group is also created for each design storm.

To use the drag-and-drop:

  1. Make sure the Project Manager is visible and not covered by Resource Library window.
  2. Select the desired climate data in the Library Explorer
  3. To create a new climate data group, drag it to the corresponding section in Project Manager:
  • for design storm and long-term precipitation
  • for temperature
  • for evaporation
  • for groundwater
  • for flow.
  • To add the climate data to an existing climate data group, drag it to existing rain group , temperature group , evaporation/groundwater group or flow group in Project Manager;
  • The cursor would change to indicate climate data can be added to current location.
  • Release mouse to finish the operation. The climate data will be added to the current location and appears in Project Manager.

Certain rules apply when adding climate data to model:

  1. The climate data to be added should have the same time step and total duration as cli-mate data in the destination climate data group. If they don’t match, the operation will be rejected as it would cause error in simulation. It also makes sense from a practical point of view.
  2. The number of data points in the storm to be added can’t exceed 2000 for single-event model.
  3. It is not recommended to mix design storm and measured storm in one rain group.
  4. For rain groups with measured storms, it is recommended to use storm data with same starting date and time.
    Note that the last two rules are not enforced in VO. It is the modeler’s responsibility to make sure they are followed.
