Investigation 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 کاملEstimation of forest parameters through fuzzy classification of TM data
Several studies have investigated the utility of Landsat 5 TM imagery to estimate forest parameters such as stand composition and density. Regression equations have generally been used to relate these parameters to the radiance responses of the TM channels. Such method is not feasible in highly complex landscapes, where forest mixtures and terrain irregularities may obscure the existence of sim...
متن کاملForest road design combining common design techniques and GIS (Case Study: 2nd series of Liresar Forest)
Nowadays, it is necessary to apply modern techniques for the design of road networks, especially roads passing through ecosystems such as forests, in order to reduce operating costs, prevent further degradation of the environment, increase road efficiency and achieve sustainable development goals. In this paper, a new way of designing the road is presented. New design method has the ability to ...
متن کاملForest Road Prism
The effectiveness of four road turn–out ditch treatments (vegetation, rip–rap, sediment fences, and settling basins) in reducing sediment export to the forest floor was evaluated. These four runoff control methods are commonly prescribed to control forest road runoff and sediments. The study utilized runoff samplers, runoff diversion walls, sediment filter bags, and erosion stakes to evaluate r...
متن کاملUsing Road Surface Measurements for Real Time Driving Simulation
Road surface irregularity is known to effect vehicle NVH responses. When modeling vehicle NVH, it is desirable to have high-resolution measurements of the road surface to use as road input. For typical NVH modal tire models, the road surface sampling rate will not be an issue because several points on the tire patch (center line) are used to determine the road surface irregularity. The single p...
