Impact of traffic characteristics on forest roads due to forest management
Traffic load and transported quantity due to forest management were analysed on the forest roads in the forest district Dragatu{, SE Slovenia. On the basis of timber gravitating to particular sections, the traffic load and transported quantity were calculated for each of seven forest road sections. The cumulative traffic load is the highest on the section connected to the public road and the lo...
متن کاملThe Effects of Some Soil Properties on Soil Loss in the Cut Slopes of Forest Roads (A Case Study: District No. 2, Series No. 5 of NekaChoob Company)
Soil erosion and its consequences are important factors in forest road network management. Cutslopes are the most important source of making sediment among different parts of the forest roads structure. For this research, a new and bare road in district No. 2, series No. 5 of NekaChoob forest, was selected; then the study data was measured. The study design was a completely randomized design in...
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 کاملBreaking criterion and characteristics for solitary waves on slopes
Shoaling and breaking of solitary waves is computed on slopes 1:100 to 1:8 using an experimentally validated fully nonlinear wave model based on potential flow equations. Characteristics of waves are computed at and beyond the breaking point, and geometric self-similarities of breakers are discussed as a function of wave height and bottom slope. No wave breaks for slopes steeper than 12 . A bre...
