Soil Erosion and Sediment Delivery in the Blue Creek Watershed, Pike County, Illinois: Preliminary Analysis

摘要

The study integrates the results of a SCS Phase II Erosion Inventory, a computerized geobased generated potential gross erosion inventory (ADAPT) and a lake sedimentation survey. The goal was to determine a sediment delivery ratio in an attempt to identify sediment source areas. This study concluded that the gross erosion for the Blue Creek Watershed is 63,313 tons (62,867 tons by sheet and rill erosion and 446 tons by gully erosion. This erosion data was correlated with lake sedimentation data from Pittsfield lake in order to determine the sediment delivery ratio. This ratio was calculated to be 66%.
