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
