Field Evaluation of The Hillslope Erosion Model (HEM) in IRAN
The development of improved soil erosion and sediment yield predictions technology is required to provide watershed stakeholders with the tools they need to evaluate the impact of various management strategies to plan for the optimum use of the land...
Microstructural analysis of sands with varying degrees of internal stability
Sedimentation problem in Tabarak Abad Dam, northeast Iran
Sedimentation problem in Tabarak Abad Dam, northeast Iran
Temporal and spatial variations of the water erosion rate
Understanding the erosion dynamics and recognizing sensitive times and places to erosion within the catchment are necessary for erosion control. The seasonal and spatial variability of soil erosion under different contrasting lithologic conditions...
Evaluating the erosion hazard of the stream banks of Karoun, south of Ahvaz,Iran
. In this study, on the basis of several criteria such as soil texture, presence and absence of retaining structures and vegetation coverage around the river, the areas exposed to the erosion have been evaluated. Moreover, using aerial photographs of different...
Evaluation the relationship between rainfall erosivity index and sediment yield in Sanganeh area, Khorasan Razavi, Iran
Rainfall erosivity, considering rainfall amount and intensity, is an important parameter for soil erosion risk assessment. The aim of this study was to evaluate the relationship between rainfall erosivity and sediment yield in Sanganeh area located...
Prediction the soil erodibility and sediments load using soil attributes
Soil erodibility (K factor) is the most important tool for estimation the erosion. The aim of this study was to estimate the soil erodibility in Sanganeh area located in Naderi Kalat, Khorasan Razavi Province of northeastern Iran. The sediments load...
Spatial Modelling of Soil Erosion Using GIS(A case study in Kermanshah, Iran)
Soils degradation and erosion represents a serious problem in the most diverse sectors of activity. In this respect, it was expressed in the 21st Session of FAO Conference that the soils must be protected against erosion being exposed to atmospheric...
Application Factor analysis for estimating soil erodibility and sediments load
Soil erodibility (K factor) is the most important tool for estimation the erosion. The aim of this study was to estimate the soil erodibility in Sanganeh area located in Naderi Kalat, Khorasan Razavi Province of northeastern Iran. The sediments load...
