I started using ParFlow.CLM, a 3D variably saturated overland flow-subsurface model for my research in small urban watersheds about six months ago. In this post, I list the skills that were needed to start using ParFlow and the right attitude to have going in to this type of project.
I’ve known about the USGS’ SSURGO database for awhile. Back when I was practicing as a civil engineer, we mostly used it to define drainage groups of soil. I did a few land development suitability analyses for some conceptual projects with it too, but nothing too intense. For my current project, I needed to use it to define the subsurface conditions of an urban hydrological model. Here I present how to extract more detailed information from the SSURGO database.
