estimate potential sediment yield in shadegan catchment with using of irifer and hierarchical models
soil erosion is a major problem for developing countries with arid and semi-arid climate. these of erosion is possible than two ways of water and wind. in this paper, with using of two methods irifer and hierarchical models, the rate and intensity of of soil erosion is estimated shadegan catchment. for this purpose, by using various maps alike dem, rainfall, land use index, ndvi, geology estima...
Perennial warm-season grasses for producing biofuel and enhancing soil properties: An alternative to corn residue removal" (2017). Faculty Publications, Department of Statistics. 45. This article has been accepted for publication and undergone full peer review but has not been through the copyediting, typesetting, pagination and proofreading process, which may lead to differences between this v...
There are some unique geomorphic phenomenon in Iran that Clutes and Chahnimes can be considered among them. There are two theories published in books and articles about the development Chahnimes in Sistan-Baluchistan province, one of which relates its development to tectonic activities and the other attributes it to the process of water and wind. And there is still a lack of documented studies ...
Wind erosion is one of the environmental problems worldwide, particularly in arid and semi-arid areas of Iran. Different methods and models have been proposed to measure and monitor wind erosion in the recent years. One of the accurate models for measuring f wind erosion is the USEPA model. The purpose of this study was to evaluate the quantification of wind erosion with the USEPA model and the...
Assessments of contaminant-related human and ecological risk require estimation of transport rates, but few data exist on wind-driven transport rates in nonagricultural systems, particularly in response to ecosystem disturbances such as forest wildfire and also relative to water-driven transport. The Cerro Grande wildfire in May of 2000 burned across ponderosa pine (Pinus ponderosa Douglas ex P...
Introduction: Due to the detrimental consequences of the application of stabilizers such as mulch and other protectives on the soil surface, including the wafting of bad smell, blackening of the ground, increasing thermal coefficient, warming of the whole area, and even destruction of plants and their unsustainability in nature, wide use of such stabilizers could not be considered as a useful s...
the influence of wind erosion on soil productivity was studied applying fan-forced wind in a wind tunnel located in the campo de nijar area in se spain where the main crops are cereals. wind erosion is highly variable depending on the type of soil (aric-haplic calcisols, aric-calcaric cambisols or aric-calcic luvisols, according to iuss working group wrb, 2014) and the time elapsed since the la...
Introduction: Wind erosion is a phenomenon that causes severe environmental changes in arid and semi-arid climates. As surface soil texture is very effective in soil erodibility, identifying soil erodibility index is important and efficient. Mismanagement greatly contributes to the development of wind erosion. The velocity that makes the first particles of soil move from the surface is called t...
ABSTRACT. Current challenges in soil erosion research have created demand for integrated, flexible, and easily parameterized sediment transport models. Most of the existing monolithic erosion models (e.g., WEPP and WEPS) are not modular, thus modifications require considerable time, effort, and expense. In this paper, the feasibility and challenges of using the Object Modeling System (OMS) for ...
