Determination of Main Agents Affecting Soil Erosion in Rainfed Land of Kermanshah Province Using Rainfall Simulator
In recent decades, low-yielding rainfed farms have become known as the main sources of sediment production and soil erosion in the country. Therefore, more research is needed on the factors affecting erosion and sediment production in these areas. This research was carried out with the aim of studying the effects of slope and rainfall intensity on erosion between rainbow trout in test farms in ...
متن کاملThe efficiency of Artificial Neural Network, Neuro-Fuzzy and Multivariate Regression models for runoff and erosion simulation using rainfall simulator
1- INTRODUCTION According to the complexity of environmental factors related to erosion and runoff, correct simulation of these variables find importance under rain intensity domain of watershed areas. Although modeling of erosion and runoff by Artificial Neural Network and Neuro-Fuzzy based on rainfall-runoff and discharge-sediment models were widely applied by researchers, scrutinizing Arti...
متن کاملpolyacrylamide effects on splash erosion rate in different soils using rainfall simulator
splash erosion recognized as first stage of erosion process that results of bombing soil surface with rain drop. falling rain drops to soil surface resulted moving soil particles and destructing soil structure. at this research effects of various pam rate (0, 2, 4 and 6 kg.ha) on splash erosion on three soil textuere clay, silty clay and sandy clay loam was tested. simulations were done with ra...
متن کاملRunoff 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 کاملDetermination of Susceptibility to Rill and Interrill Erosion of some Semi-Arid Soils using Rainfall Simulator in Laboratory Conditions
In semi-arid regions, soils are weakly aggregated and subjected to water erosion processes especially rill and interrill erosion. There is no information on the rate of these water erosion types in semi-arid soils located in the hillslopes. Therefore, this study was conducted to determine the soils susceptibility to these erosion types in semi-arid region. A laboratory experiment was done in ei...
