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 document for more details. However, my CN calculation provide me an empty output with the following message on it. Would you please help me figure this out. ================================================================================ Runoff Curve Number Report (Generated by WMS) ================================================================================ Fri Oct 20 13:43:33 2017 Thank you, Lalith
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 the help and have a good WE, S. Berendsen
