| Abstract/Description or Keywords | Hydrologic recovery is defined as the process by which the hydrologic characteristics of a watershed that has been subject to harvesting are restored to near pre-harvest condition by forest regeneration. Although the relation between the level of clearcut and hydrology at the watershed scale is not well understood threshold rate of cuts continue to be used to constrain forest management in British Columbia (BC). Until this relation is understood in a quantitative manner we may be unduly restricting forest development at great cost to the industry. The urgency to understand how clearcut affects hydrology has increased with recent pine beetle epidemics and wildfires that are creating disturbances in large watersheds equivalent to 100% ECA. In this project, we use the University of British Columbia Watershed Model (UBCWM) at two interior snow dominated watersheds to quantify the effects of total clearcut of an entire watershed and investigate the nature of the relationship between these effects and hydrologic recovery over time. The main focus of the project is the effects of clearcut on the water yield and peak flow regime. model, peak flow, low flow, ECA, watershed assessment |
