Investigating 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 کاملThe effect of surface rock fragments deployment pattern on soil erosion processes under simulated conditions
Extended abstract 1- Introduction The Soil surface characteristics have significant effects on the erosion process. The wide areas of watershed soil surfaces are covered with considerable amounts of rocks and pebbles. Surface rock fragments, resulting in water connectivity, change during the erosion process. Rock fragments on the soil surface may increase the infiltration and reduce soil loss...
متن کاملThe Effect of Leaf Litter Cover on Surface Runoff and Soil Erosion in Northern China
The role of leaf litter in hydrological processes and soil erosion of forest ecosystems is poorly understood. A field experiment was conducted under simulated rainfall in runoff plots with a slope of 10%. Two common types of litter in North China (from Quercus variabilis, representing broadleaf litter, and Pinus tabulaeformis, representing needle leaf litter), four amounts of litter, and five r...
متن کاملTrend and pattern analysis of runoff and sediment in different soil clay contents and surface rock fragments
Different factors affect the runoff and sediment production during storm conditions. Among different soil properties, clay content is one of the most important bonding agents for aggregation and infiltration. Rock fragments also affect hydrological and erosional processes, but these relationships in various soil clay contents or surface rock fragments may be positive or negative, thus examinati...
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 کاملThe effect of sand mulch on runoff and erosion control of the catchment surface
Due to population growth, global warming, changing precipitation patterns, and decreasing precipitation, water and soil are two of the most important human issues. Water and soil resources management in arid and semi-arid regions is one of the methods that can solve water and soil issues. Covering the soil surface with permeable natural materials can reduce water and wind erosion and evaporatio...
