SCS Curve Number for NB Ralston Creek (1972)

Determine the composite curve number (CN) appropriate for the North Branch Ralston Creek to be used in simulating the flood on 17-18 July 1972. The SCS land use and land cover types are provided for the 3.01 square mile area. Use this information to compute the following:

  1. CN (AMC II) for each land use class.
  2. The composite CN (AMC II) for the entire watershed.
  3. The composite CN (AMC III) for the entire watershed (HINT: Use the result from part b).
