Using all available hydrologic data

An approach to the use of both meteorological and streamflow data has been developed by S.J. Solomon et al, and applied in Labrador. In this method, a river basin is divided into a number of squares, physiographic parameters are determined for each square, meteorological data are correlated with these parameters and from the resulting equation estimates are made of precipitation, evaporation and runoff for each square. Accumulated runoff is compared with measured runoff.This paper describes an attempt to apply the method to a mountainous area in the interior of British Columbia to determine the areal variation in runoff and also to extend the method by using snow course data as well as meteorological and stream gauge data. The results are promising and the technique has important implications for data network design.
