Runoff and Soil Erosion Assessment on Forest Roads Using a Small Scale Rainfall Simulator
Forestry operations can significantly alter hydrological and erosional processes in a catchment. In the course of developing timberland, a network of persistent roads and skid trails causing soil compaction is usually established. Hereby, the infiltration rate of the soil is distinctly reduced, which leads to the generation of overland flow—this may also cause soil erosion. In this study, a sma...
متن کاملEffects of Soil Surface Rock Fragments on Runoff Variables of Field Plots under Rainfall Simulation
Soil surface rock fragment is considered as an important factor on runoff and soil erosion. However, few studies have been focused on quantitative evaluation of the effect of soil surface rock fragments on runoff components as an integral part of soil erosion process especially in natural conditions. The present study has been conducted to evaluate the effect of soil surface rock fragments ...
متن کاملcomparing runoff and soil erosion in forest, dry farming and garden land uses soils using rainfall simulator
abstract land use change, especially natural ecosystems transformation, has high effects on soil physico-chemical as well as biological characteristics and also, has effect on runoff and soil erosion. analysis of runoff and soil erosion dynamics can be useful in improvement of management proposals and quantifying runoff and soil erosion changes. so, this research was carried out to investigate ...
متن کاملInvestigating the Effect of Surface Gravel Cover on Runoff and Soil Erosion with Simulating Runoff
Surface gravel cover is an important factor for contoroling of soil erosion in dry area specially in area that plant can not grow because of excessive dryness and salinity. The objective of this study was investigation effect of different surface gravel cover on runoff and sediment yeild. For this porpose, 36 field plots with 20 meter length and 0.5 meter width at 3 percent slope were construct...
متن کاملRunoff and suspended sediment yields from an unpaved road segment, St John, US Virgin Islands
Unpaved roads are believed to be the primary source of terrigenous sediments being delivered to marine ecosystems around the island of St John in the eastern Caribbean. The objectives of this study were to: (1) measure runoff and suspended sediment yields from a road segment; (2) develop and test two event-based runoff and sediment prediction models; and (3) compare the predicted sediment yield...
