The physically based Distributed Hydrology Soil Vegetation Model (DHSVM) is developed, calibrated, and applied in a long-term simulation experiment to quantify the effects of mountain pine beetle infestation and treatment alternatives on the streamflow characteristics of snow-dominated interior watersheds ranging in scale from tens to hundreds of square kilometres. Predicted increases in peak flow that result from pine beetle infestation and salvage logging were used to investigate potential effects on channel geomorphology. The study is being conducted on the Baker Creek drainage, located near the confluence of the Upper Fraser and Quesnel Rivers in the North Cariboo region of British Columbia. A wealth of historic long-term and newly collected more intensive short-term measurements of hydroclimatic data supports this numerical modelling study. This project integrates results from several completed and ongoing stand-level Federal Mountain Pine Beetle Program research projects into operationally critical watershed scale functions related to the hydrogeomorphic regimes.
