Hi, I am trying to calculate curve number for a watershed using soil type and land use data. I am required to use watershed boundary, longest flowpath and drainage point shapefiles from another program. I also have GIS shapefile of soil type and land use. First I made the drainage coverage and projected watershed boundaries, longest flowpath and drainage point shapefiles. created the polygons and calculated basin data. Then I tried to calculate the CN using soil and landuse shapefiles. I used a land use table created by me using the soil and land use data. Please see the attached doc
Hello All, I'm trying to automatically assign material types to a mesh according to the local land use pattern. So far I've found two ways: 1.) for an existing mesh, manually assign each element one material type 2.) assign the polygons, which are used to bound the auto-generation areas, a material type and then generate the mesh 1. is, especially on larger meshes, very error-prone and time-consuming. 2. is possible, if one can generate the mesh from polygons - which isn't always possible or feasible. Is there a way to assign material types to an existing mesh using a polygon-shape? Thanks for
