| 127 | 127 | Among these new extensions there is a set of components, **r.gsflow.*** and **v.gsflow.***, that uses GRASS GIS to create inputs for the integrated hydrologic model [https://water.usgs.gov/ogw/gsflow/ GSFLOW]. Developed by the US Geological Survey, GSFLOW combines the groundwater model MODFLOW with a rainfall-runoff model, PRMS, but lacked a streamlined way to generate inputs and execute the model. The new GRASS GIS addons build the computational domain for the model, including nested sub-basins for runoff, grid cells for groundwater, and segments for the stream network that are required by GSFLOW; they then export their attributes, which are read in by [https://github.com/umn-hydro/GSFLOW-GRASS GSFLOW-GRASS] to create the input files and run GSFLOW. In this (yet unpublished) [https://www.geosci-model-dev-discuss.net/gmd-2017-321/ paper] it is possible to find more information and details about the workflow to run GSFLOW model. |
