Toward the Use of Coupled Atmospheric and Hydrologic Models at Regional Scale

The model Waterloo flood forecasting system (WATFLOOD) used here is sensitive enough to detect problems associated with the mesoscale atmospheric simulations and also with the radar observations. Modeling description a. Atmospheric model The use of an atmospheric model having the ability to solve the Euler equations at very high spatial resolution was essential for this study, given the use of radar observations and some model simulations at nonhydrostatic spatial resolutions. [...]we would like to especially thank the B.C. Hydro Company (B. Chin and D. Cattanach) for the strong link created between hydrologists and atmospheric researchers.
