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 ...
متن کاملEstimating sediment yield from a paved forest road (Asphalt) (Case study: Watershed Leyle, Ravansar)
Extended abstract 1- Introduction Forest roads are among the largest sediment transport sources to drainage network. So, estimating the sediments of the road network is an important factor in the evaluation of the impact of the road construction. One of the biggest problems caused by the road construction in the forest is the increase in various forms of erosion, such as Gully erosion and mas...
متن کاملInvestigation of forest road surface sediment estimation using two experimental models of SEDMODL and WARSEM
Extended abstract 1- Introduction A bare surface on forest roads is created due to road construction. This surface is the main source of erosion and sediment yield to streams in forest areas. The increase of sediment in streams causes dramatic damage to the quality of water ecosystems and the life of aquatic organisms. Therefore, road engineers should pay attention not only to the cost of roa...
متن کاملSediment yield estimation using GIS
A method has been developed in the present study for the determination of the sediment yield from a catchment using a GIS. The method involves spatial disaggregation of the catchment into cells having uniform soil erosion characteristics. The surface erosion from each of the discretized cells is routed to the catchment outlet using the concept of sediment delivery ratio, which is defined as a f...
متن کاملassessment of the efficiency of s.p.g.c refineries using network dea
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
