Sediment production from forest roads in western Oregon
Prevention and estimation of soil erosion from forest roads requires an understanding of how road design and maintenance affect sediment production. Seventyfour plots were installed on forest roads in the Oregon Coast Range to examine the relationship between sediment production and road attributes such as distance between culverts, road slope, soil texture, and cutslope height. An additional c...
متن کاملForest 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 ...

متن کاملA GIS Tool to Analyze Forest Road Sediment Production and Stream Impacts
A set of GIS tools has been developed (Road Sediment Analysis Model, RSAM) to analyze and quantify the impacts of forest roads on forested watersheds. RSAM is organized into three modules. In the first module sediment production for each road segment is calculated from slope, length, road surface condition and road side drain vegetation. A GPS gathered road condition inventory provides surface ...
متن کاملAn effective strategy to reduce blood pressure after forest walking in middle-aged and aged people
[Purpose] Forest walking may be effective for human health, but little information is available about effects of energy expenditure on blood pressure responses after forest walking. The aim of this study was to investigate the relationship between the activity energy expenditure and changes in blood pressure in individuals after forest walking. [Subjects] The subjects were 54 middle-aged and el...
