The ''Output Control'', accessible from the ''Job Control'' dialog, is where most of the output options for a GSSHA simulation are set. GSSHA can write out two types of datasets: grid based and link/node (point) based. All of these data sets will be read in to WMS, if they exist, as part of a GSSHA solution.

Specify how often to write output values to the grid and the link/node output files.

Data for link/node datasets are output before the first computation time step (initial values) and then according to the specified write frequency. Using the previous example link/node data sets are written at 0 seconds, 30 minutes 0 seconds, 60 minutes 0 seconds, and so on.

GSSHA Output Control dialog.

The GSSHA Output Control dialog is accessible by clicking Output Control... in the Job Control dialog. Most of the output options for a GSSHA simulation are set in this dialog. GSSHA can write out two types of datasets: grid based and link/node (point) based. All of these datasets will be imported into to WMS, if they exist, as part of a GSSHA solution.

At the bottom of the dialog are the following buttons:

  • Help – Opens this article in a web browser.
  • OK – Saves all changes and exits the GSSHA Output Control dialog.
  • Cancel – Discards all changes and exits the GSSHA Output Control dialog.

Each section of the dialog is discussed below.

Gridded Datasets

The Gridded datasets section includes a drop-down for selecting the Data type and a list section where options can be turned on or off. Because there are so many gridded datasets that GSSHA can output, they are separated into two categories. The Data type drop-down allows for selecting between the two options: "General" and "Nutrients – Overland".

  • Cumulative groundwater recharge – Turn on to output the total groundwater recharge for the simulation.
  • Suspended sediment concentration – Volume of suspended sediments

Write Frequency

The Write frequency section allows for specifying how often to write output values to the grid and the link/node output files. GSSHA will output data for a gridded dataset after the first computational time step and then using the specified write frequency. For example, a 2 hour simulation with a time step of 30 seconds and a write frequency of 30 minutes will produce output at 30 seconds, 30 minutes 30 seconds, 60 minutes 30 seconds, and so on. Data for link/node datasets are output before the first computation time step (initial values) and then according to the specified write frequency. Using the previous example, link/node data sets are written at 0 seconds, 30 minutes 0 seconds, 60 minutes 0 seconds, and so on.

Gridded Dataset Output Format

The Gridded dataset output format section allows for selection of the file format for the output files.

  • Binary – Outputs files in an encoded binary format.
  • ARC/INFO® ASCII – Outputs files in an ARC/INFO ASCII text format. Can be viewed with any text editor.
  • GRASS ASCII – Outputs files in a GRASS ASCII text format. Can be viewed with any text editor.
  • XMDF – Outputs files in the XMDF format.

Hydrograph

The Hydrograph section allows specifying the write frequency and output units for outlet hydrographs. GSSHA will output the outlet hydrograph to the OTL file using the specified write frequency. Even though GSSHA performs all computations using metric units, it is possible to have GSSHA output flows to the outlet hydrograph file in either metric or English units.

Other

The Other section contains a number of options that can be turned on or off:

  • Suppress screen printing – Suppresses the output of runtime data from GSSHA at each time step, significantly reducing the overall run time required for a GSSHA simulation. This option can also be selected in the GSSHA Run Options dialog.
  • Suppress long term simulation printing – Suppresses the output of runtime data from GSSHA at each time step during a long term simulation, significantly reducing the overall run time.
  • Strict Julian dates – Write all dates to output files using strict Julian dates.
  • Output contaminants – Output contaminant information.
