| Method | Specific Catchment area computed from the original digital elevation model using the TauDEM (http://hydrology.usu.edu/taudem) Dinfinity method as described by Tarboton, D. G., (1997), "A New Method for the Determination of Flow Directions and Contributing Areas in Grid Digital Elevation Models," Water Resources Research, 33(2): 309-319. The following processing steps were used: 1. Fill Pits 2. Dinfinity Flow Direction 3. Dinfinity Contributing Area |
