Yield Frontier Analysis of Forest Inventory
Standing inventory analysis allows a forester to predict the yield (volume by logtype) of a section of forest before the trees have been felled. Current standing inventory tools such as MARVL and ATLAS Cruiser predict yield. They do this by simulating the bucking that will take place when the trees are harvested. These tools produce a point estimate of the yield for given input data. In practic...
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 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 کاملDistributed sediment yield modelling: Importance of initial sediment conditions
The importance of initial sediment conditions on model calibration and validation is analysed. A sediment model was calibrated and validated under three different initial sediment conditions: (0) no sediment availability, (1) calibration of the initial sediment condition and (2) using a warm-up simulation. The model results were assessed in terms of the graphic of fine sediment transport, or se...
متن کاملWater yield following forest–grass–forest transitions
Many currently forested areas in the southern Appalachians were harvested in the early 1900s and cleared for agriculture or pasture, but have since been abandoned and reverted to forest (old-field succession). Land-use and land-cover changes such as these may have altered the timing and quantity of water yield (Q). We examined 80 years of streamflow and vegetation data in an experimental waters...
