===SWMM Options===
Note: In Module 1 we included '''Project--Options''' in the GeoPackage file. Project--Options define the SWMM simulation controls, such as hydrology computation timestep. Project--Options are not required in the new geopackage database we are creating for this Tutorial. This is because this model will be constructed from multiple SWMM input (INP) files:
*The SWMM INP file created during Module 1 (road culverts).
*The SWMM INP file careted for Module 2 (underground pipe network inputs).
*This Module's SWMM INP (SWMM urban hydrology).
When TUFLOW processes SWMM inputs, it combines the multiple INP files into one single INP prior to simulation. For this model, the simulation control parameters defined in the Module 1 '''Project--Options''' will apply. Options relevant to this tutorial that have already been defined in the Module 1 input include:
* '''flow_units''':set to metric.
* '''infiltration''' method: set to Green Ampt.
* '''wetstep''' hydrology timestep: set to 1 minute.
* '''dry step''' hydrology timestep: set to 1 minute. <br>
''Note: If we wanted to change the Project--Options as a result of this modules additonal data, Project--Options should have been included as a item in the SWMM Geopackage creation step. The information contained in this files SWMM Geopackage would superseed any infromation previously defined by the Module 1 file if the SWMM input file refence is specified lower in the TCSF control file.''
