USE OF TOPOLOGICAL INFORMATION IN HYDROGRAPH ESTIMATION.

January 1, 1987

Discharge hydrographs computed from the theory of linear flow through topologically random channel networks are compared to actual discharge hydrographs for basins in semiarid regions of central Wyoming. The basins drained by the channel networks range in the size from 0. 69 to 10. 8 square miles. Topological information consisting of stream-network magnitude and link-length distribution parameters are used in calibrating celerity values that ensure that the peak discharge and excess rainfall volume of the resulting computed hydrographs match the peak discharge and excess-rainfall volume of the actual hydrographs. Results indicate that, for a given peak discharge and excess-rainfall volume in a basin, the sensitivity of the calibrated celerity values to excess-rainfall duration is small if the ratio of excess-rainfall volume to peak discharge is at least 1. 75 times the excess-rainfall duration.
