Figure: OSI - Action Buttons

The Action Buttons ("Figure: OSI - Action Buttons"), located to the right of the Table Panel on each tab of the OSI, include the following:

  • Compute—Computes the current alternative associated with the OSI. Can be used to compute results after changes are made using the Table or Graphical Editors.
  • Calculate All Locals—Computes the values for all Local Flow Variables across all tabs for the entire simulation period when observed flows are available. See Section I.6 below for a description of how to configure the alternative and the OSI to compute Local Flow Variables.

    This compute option runs a special ResSim simulation type to override computed Junction outflow values with observed time series data whenever the observed data is available. When the simulation is complete, all local flow time series associated with a Local Flow OSI Variable are adjusted to make up the difference between total inflow to the Junction and the observed value at the junction outflow. Note: for this calculation to work, observed flow data must be provided for the Junction outflows. Also Note: the Known Flow time series in the ResSim simulation.dss file will be overwritten with the calculated local flows. A second, normal ResSim compute is then launched to use the computed local inflow data and thus refresh all output data.
  • Calculate Selected Locals—Computes the values for the selected Local Flow Model Variables in the current tab and only for the time steps before and including the currently selected row in the table.
  • Hydrograph Recession—Computes the recession hydrograph for the selected Local Flow Model Variables from the selected time to the end of the simulation period. If the only cell selected is in the Date/Time column, then the recession hydrograph will be calculated for all Local Flow Model Variables on the current tab. Note: Known Flow time series in the ResSim simulation.dss file will be overwritten with the calculated results. Recession parameters are defined independently for each Local Flow Model Variable through the OSI Model Variable Editor.
  • Clear Selection—Sets local flows to zero and removes release and elevation target overrides from the selected model variables for the selected time range.
  • Clear Below—Sets local flows to zero and removes release and elevation target overrides for the selected model variables beginning with the first time step of the selected time range and ending at the end of the simulation time window.
  • Clear All—Sets local flows to zero and removes release and elevation target overrides for the selected model variables for the whole simulation time window. For local flows, this includes the lookback period.
  • Refresh Plot—Changes made to the configuration of a variable will not show in the Plot Panel until an action forces the plot to refresh. Clicking in the column of another variable then clicking back in the one you reconfigured is one such action; clicking the Refresh Plot button is another.
