Soil erosion risk is one of the most severe environmental problems that can affect water availability, agricultural productivity and consequently countries’ sustainable development worldwide. The current study was performed in Oued El Hamma Catchment, South-Eastern Tunisia to estimate soil loss, applying Universal Loss Equation (USLE) integrated with Geographic Information System (GIS) Remote S...
The erosion caused by the action of rain is one most frequent environmental problems, and it causes several damages, both material human. aim this research was to evaluate dynamics based on a quantitative analysis soil loss in Jaboatão river basin, located coast Center Forest Area Pernambuco. With focus applying Geoprocessing resources, used Universal Soil Loss Equation (USLE), which integrates...
One of the important parameters, that reduce negative influence of the other known parameters, is cover vegetation. In this study were estimated cover vegetation influence in soil erosion of Razin basin in Kermanshah province that is our study area. The first step is preparation map of NDVI obtained & category of cover vegetation by the Landsat TM data. Then Revised Universal Soil Loss Equation...
Abstract. Rainfall erosivity quantifies the effect of rainfall and runoff on rate soil loss. Maps are needed for erosion assessment using Universal Soil Loss Equation (USLE) its successors. To improve maps that currently available, hourly daily data from 2381 stations period 1951–2018 were used to generate new R-factor 1-in-10-year event EI30 mainland China (available at https://doi.org/10.1227...
bekenstein and hawking by introducing temperature and every black hole has entropy and using the first law of thermodynamic for black holes showed that this entropy changes with the event horizon surface. bekenstein and hawking entropy equation is valid for the black holes obeying einstein general relativity theory. however, from one side einstein relativity in some cases fails to explain expe...
A software package was assembled and evaluated for assessing the potential of soil erosion due to agricultural development within the Nzoia River basin (Kenya). Google Earth Pro was used to define site characteristics. An extensive analysis of the components of the Universal Soil Loss Equation (USLE) and the US Forest Service sediment delivery ratio method was made to determine erosion potentia...
Erosion Level Analysis and Conservation Planning Based on Geographic Information Systems in Rendang District, Karangasem Regency, Bali Province. The factor of rapid population growth leads to land conversion slopes used as agricultural land. In District erosion can be caused by unaccordance use with conservation principles Regosol soil types. This study aims determine the level its distribution...
“any science seeks generalities; the aim is to transcend knowledge of particular cases by discovering general regularities or laws” (chesterman, 2001, p. 1). these were the words of chesterman whose paper has served as a typical example of numerous papers carried out on ‘translation universals’ since the mid-nineties. blum-kulka (1986) is among translation studies scholars who proposed ‘explici...
abstract in this thesis at first we comput the determinant of hankel matrix with enteries a_k (x)=?_(m=0)^k??((2k+2-m)¦(k-m)) x^m ? by using a new operator, ? and by writing and solving differential equation of order two at points x=2 and x=-2 . also we show that this determinant under k-binomial transformation is invariant.
