Distributed watershed model compatible with remote sensing and GIS data. II: Application to Chaudiere watershed

In an accompanying paper, the HYDROTEL model, a distributed hydrological mo del compatible with remote sensing and GIS, has been presented. Run on micr ocomputers with a user-friendly interface, the HYDROTEL model can be applie d to a wide range of watersheds with due account for available data, as a c hoice of options is offered for the simulation of the various processes. In the present paper, the HYDROTEL model is applied to the Chaudiere watershe d, a 6,680 km(2) medium-size watershed, for both summer- and yearlong simul ations and the results are discussed. In particular, the evolution of the s nowpack throughout the winter and spring is compared to snow survey data at many sites on the watershed. With its display options allowing monitoring of various variables during a simulation run, the HYDROTEL model appears to be a good tool for understanding and managing phenomena related to hydrolo gical processes.
