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 کاملdetermination of culverts diameter in forest roads
construction of forest roads disorders the natural trend of water movement. it is vital to make ditch and cross line drainage culvert to prevent the area from being destroyed and conduct the water of streems and vallies. determination of culvert diameters depends on the information of area discharge, physiographic characteristic, vegetation cover and site land use. in order to determine the amo...
متن کاملMore important sediment factors in forest roads in the northern Iran forests
Abstract The forest road is most important sediment sours in the forest regions. the forest roads with remove vegetation cover and disorder hydraulic behavior regions, causes sediment product and problems due of sediment. This study has been done to surveying sediment factors roll in the sediment producing in the northern forest road. For this goal were selected purpose road sections by using h...
متن کاملThe use of a Rotary Asphalt Broom to Groom Aggregate Forest Roads
Due to the dispersed nature of forestry operations in much of the world, only a subset of a given forest road network are used in any year. Specifically, spur roads are generally only used when harvesting operations are adjacent to roadways; otherwise, they remain unused or only have infrequent administrative traffic. During these periods of light use, a substantial amount of organic litter may...
متن کاملImagining the Northwest : A Digital Library Partnership in Oregon
This paper documents the development of a digital library of still images created by photographer Lee Moorhouse on the Umatilla Indian Reservation at the turn of the 20th century. The University of Oregon Libraries, working with the Tamastslikt Cultural Institute of the Confederated Tribes of the Umatilla, developed a Dublin Core compliant metadata structure. The metadata structure accommodates...
