| Abstract/Description or Keywords |
The WRENSS procedure is a technique for evaluating the effects of timber removal on water resources. A modified version of the hydrology portion of this procedure (CFS-WRENSS) was assessed for application in south central British Columbia through the opportunistic use of hydrologic data available for the Camp Creek watershed. When compared to the results obtained through the standard paired basin approach, this procedure closely predicted the change in average annual water yield (mm) following timber removal from 27% of the watershed. However, differences in average annual water yield generated by each approach resulted in an estimated increase in water yield over predicted "no harvest" yields of 10% by CFS-WRENSS compared to 24% by the standard paired basin approach. The need for regional research basins to provide local process oriented data is clearly demonstrated. Such data would prove useful in the adaptation of computer procedures such as CFS-WRENSS for local forestry applications. model, forest harvest, ECA, streamflow, water yield, water supply |
