| Abstract/Description or Keywords |
This study assesses the influence of forest encroachment on the water balance of Burns Bog in Delta, British Columbia by determining the differences in the evapotranspiration and interception losses between a forested and non-forested (open) bog site. Throughfall in the forested bog site was 88% of the precipitation. During the growing season (June 15 – September 15, 2009), average evaporation in the open bog site, was 0.9 mm/day. The average evapotranspiration from the forested bog site was 0.7 mm/day; average transpiration was 0.4 mm/day while the average evaporation rate was 0.3 mm/day. Water storage was greater in the open bog site, with higher water levels and soil moisture. Deep drainage accounted for up to 10% of the water balance at both sites. A water balance model that requires few input variables was successfully created and calibrated and can be used to simulate water levels in Burns Bog. |
