Forest harvesting can have a significant effect on hydrologic processes such as interception, snowmelt, and evaporation, as well as on the magnitude and frequency of geomorphically and ecologically important stream-flow events. These changes may affect water supplies, channel form, and the functioning of stream/riparian ecosystems. This note describes preliminary research modelling the effects of forest cover removal on peak flows in a small headwater stream in the south-central Okanagan.
