Line 4: =Available models= ~~Currently, the~~The tool is available for catchments in the Auckland Region<sup>1</sup>~~, however, further models are planned to be added~~. ==Auckland Region== The model is recommended for use in stormwater management design in the Auckland Region. It is designed as a standard tool that provides consistent results from different users. Key features of the stormwater runoff model are: Line 26: ==Model Selection== Currently, Auckland Region (TP108) is made available as the catchment location. This setup comes with curve number for impervious areas of 98, initial abstraction of 5mm for pervious areas and 0mm for impervious areas.<br> <br> [[File: Plugin_SCS_Model_Selection.png]] Line 50: ==GIS Approach== The GIS approach allows a GIS ~~layers~~layer to be used as a source of catchment parameters and as such a catchment with multiple subcatchments can be processed in once. The subcatchment layer name is to be selected in the first drop down menu. Attributes from the layer will then become available to select as the catchment parameters in a similar way as for the manual approach. In addition, time of peak and time of concentration can also be calculated from a DEM and a streamline layer.<br> ~~This functionality is currently under construction and will be made available in the near future.<br>~~ <br> [[File: Plugin_SCS_GIS_Approach.png]] Line 57 ⟶ 56: ==Output location== Specify output location where inflows for every event in csv format, bc_dbase and TUFLOW event file ~~will~~are to be saved. The tool also saves input_log text file that can be used as a check of ~~what~~input ~~has been entered into the tool~~parameters. This file isn't being read into TUFLOW.<br> <br> [[File: Plugin_SCS_Output.png]] Line 63 ⟶ 62: ==Running the tool== Once all above is set, hit the "Run" button in the bottom right corner. If there are any missing/incorrect information, the tool will prompt to fill/correct these before continuing. When all input data are filled correctly, the progress bar ~~will get~~gets active and "Processing Data Into TUFLOW Format . . ." note ~~will appear~~appears in the bottom left corner. Once all hydrographs and other outputs are processed the note ~~will change~~changes to "Finished Successfully".<br> <br> =Summary= This page provides instructions of how to use the SCS to TUFLOW tool within the QGIS TUFLOW plugin to obtain inflow inputs for use within TUFLOW model. This requires the input of design rainfall depths for selected events and catchment parameters. Apart from the inflow inputs the tool also creates boundary database and event file that can be read directly into TUFLOW.<br> If you encounter any issues with the ~~plugin~~tool please email [mailto:support@tuflow.com support@tuflow.com].<br> <br>
