Abstract

Abstract - Over the past decade, the U.S. Forest Service has monitored the subsurface hillslope flow of the E-road swale. The swale is located in the Caspar Creek watershed near Fort Bragg, California. In hydrologic year 1990 a logging road was built across the middle section of the hillslope followed by a total clearcut of the area during the following year. Development of the logging road has resulted in a large build up of subsurface waters upslope of the road. The increase in pore pressures behind the road is of major concern for slope stability and road failure. A conceptual model is developed to describe the movement ofwater within the E-road groundwater system. The two-dimensional SUTRA model is used to describe both saturated and partially saturated flow within the system.
