Publication Series: Abstract
Description: A set of GIS tools to analyze the impacts of forest roads on streams considering sediment production, mass wasting risk, and fish passage barriers, has been developed. Sediment production for each road segment is calculated from slope, length, road surface condition and road-side drain vegetation gathered by a GPS inventory and by overlaying the road path on a Digital Elevation Model (DEM). Sediment production is accumulated to drain points by adding the sediment production from contributing road segments. These drain point sediment loadings are then used in a DEM weighted flow accumulation function to calculate sediment load inputs to streams based on inventoried delivery. Inventory information on the fish passage status of stream crossings is used to demarcate contiguous clusters of stream habitat and assess the impact of fish passage barriers on the extent of habitat.
Keywords: geographic information systems (GIS), forest roads, sedimentation, streams, environmental impacts, Digital Elevation Model (DEM)
