Geographic Information Systems (GIS) in combination with soil loss models can enhance evaluation of soil erosion estimation. SAGA and ARC/INFO geographic information systems were used to estimate the ...
Assessment of Soil Loss Using WEPP Model and Geographical Information System     WEPP  GIS  Soil erosion  Watershed       font style='font-size:12px;'> 2015/8/14
Severe soil erosion has generally been regarded as a major cause of land degradation in arid and semi arid regions. A quantitative assessment of soil loss intensity is still scanty for developing appr...
A STUDY ON QUANTITATIVE MONITORING OF SOIL LOSS IN SMALL WATERSHED BASED ON GIS     soil loss  GIS  RUSLE  small watershed       font style='font-size:12px;'> 2015/8/10
Soil erosion is a serious environmental and production problem in the Three Gorge Areas (TGA) of China. The objectives of the study were to develop and validate a soil erosion-predicting model based o...
The hazards from wind, sand, and soil erosion caused by human activities, such as residue slopes in abandoned urban mines, have resulted in a vicious circle of environmental degradation. Selecting t...
With increasing mechanization of forest harvesting operations the impacts on soil have increased quite dramatically. The objective of this paper was to examine the relationship of slope and soil loss....
The effects of Rubus hyrcanus L. and Philonotis marchica (Hedw.) Bridon on runoff generation and soil loss from cutslopes of forest roads were investigated. The study was conducted at the northern for...
To determine specific characteristics necessary for the computation of the C factor in RUSLE for timevariable crops, measurements were carried out in fields with selected agricultural crops grown by c...
Assessment of Soil Loss Using WEPP Model and Geographical Information System     Modeling  WEPP  GIS  Soil erosion       font style='font-size:12px;'> 2015/1/9
Severe soil erosion has generally been regarded as a major cause of land degradation in arid and semi arid regions. A quantitative assessment of soil loss intensity is still scanty for developing appr...
Soil erosion is one of the most important environmental problems, and it remains as a major threat to the land use of hilly regions of Tripura. The present study aims at estimating potential and actua...
Soil erosion is a growing problem especially in areas of agricultural activity where soil erosion not only leads to decreased agricultural productivity but also reduces water availability. Universal S...
A soil erosion experiment was conducted in northern Vietnam over three rainy seasons to clarify the magnitude of soil loss and factors controlling water erosion. The plot had a low (8%) or medium (14....
Soil Loss Estimation on a Local Scale for Soil Conservation Planning     USLE  GIS  Soil       font style='font-size:12px;'> 2009/9/10
A soil loss estimation of crop fields on a local scale was carried out using the Universal Soil Loss Equation (USLE) and Geographic Information System (GIS) tools. The study site covering 3,009 ha in ...
Soil erosion from fields located in the hilly lands of Shikoku was investigated. These are the areas where agricultural practices are quite limited and fields are often left idle and unutilized. Based...
Viewed from the erosion control in Hinoki cypress plantations, the dynamics of undergrowth was studied in order to apply the stand density control to vegetation control. Seventeen study plots were set...
GMDWD while organic carbon, % clay content and Fe.O. are some soil characteristics that predict the potential of these soils to erode fairly accurately. Dispersion and flocculation are shown to be in...
