Running GSSHA:Project file
The project file definition is made up of a series of cards followed by parameter(s) (usually a file name) related to that card. For example, the watershed mask is defined on a single line using the card WATERSHED_MASK followed by the name of the file containing the watershed mask. The project file informs GSSHA which simulation options (e.g., overland flow, infiltration, long-term, etc.) to perform along with all of the necessary parameters required for the desired options. An example project file is shown below:
