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 ...
Spatial Modelling of Soil Erosion Using GIS(A case study in Kermanshah, Iran)
factors. Soil erosion and sediment are very important in Iran, specially, in mountainous watersheds. It is estimated that 70% of the country is exposed to soil erosion. UNDP (1999) reported that mean soil erosion in Iran is about 20 ton per acre, which...
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 ...
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...
Economic Cost of Soil Nutrients Loss from Summer Rangelands of Nour-rud Watershed in North of IRAN
.0 to 996.06 t ha-1 y-1. Also, 114.17 kg ha-1 y-1 of N, P, K elements were lost in 2010 due to soil erosion in the degraded rangelands which costs (738944 Rial) 71.5 US$ ha-1y-1. Total economic cost of soil nutrient loss in 94978.6 ha of the rangelands...
Macroeconomic Policies and the Best Environmental-Oriented Policy in Agricultural sector of Iran(Case of Soil Erosion).
This paper investigated how the appropriate environmental policy may change during a long-term macroeconomic planning and under different policy weights. For this purpose, a simple general equilibrium model has been ...
Investigating the effect of vetiver and polyacrylamide on runoff, sediment load and cumulative water infiltration
Soil erosion is one of the most critical environmental problems currently facing Iran, and soil conservation is crucial for managing natural resources. The objective of this study was to investigate the effect of a vetiver cultivation system, known...
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...
Comparison the conservational management practices on wind erosion in Tabas region
Introduction: Wind erosion is a serious problem in many parts of the world, especially in arid and semi-arid regions. Prevention and protection operations against the wind erosion are appropriate practices to manage the ...
