Forest Road Sediment Production Analysis Using Dynamic Segmentation

Forest Road Inventory and Assessments have focused primarily on stream crossing evaluation. Recently, interest has turned to methods of defining hydrologic connectivity in the road system as an important element for evaluating potential impacts of forest road systems on fishery resources. This paper presents a GIS/database system and the associated field inventory used to document and manage a suite of point and linear events using dynamic segmentation at a one foot resolution. These derived spatial features are then used in an analysis of sediment production rates throughout the road system routed through a series of hydrologically connected events derived from the dataset and defined as network elements.
