Abstract
The set up and parameterization of a hydrological model is described for a watershed extending from the continental divide along the Rocky Mountains into the grasslands of southern Alberta, Canada. The hydrological model WATFLOOD (a flood forecast model), based on the group response unit (GRU), was used for a 13-month stream flow simulation. Required monthly surfaces of snow water equivalent were derived by integrating spatial precipitation patterns, orographic effects and topography-induced microclimate. Spatial and temporal changes in radiation and temperature were modeled at a 100 m resolution to simulate the snowmelt and accumulation processes using MTCLIM (a mountain microclimate simulation model). The simulated surfaces of snow water equivalent enabled the optimization of WATFLOOD parameters using GLUE, a Monte Carlo simulation tool for estimating the predictive uncertainty of models. This was important, because the majority of stream flow in this region originates as snowmelt. The verification of the stream flow simulations indicates that WATFLOOD is applicable in mountainous watersheds.
