Currently gravity irrigation remains the most widely used in agricultural areas and 90 percent of plantings, the water is applied to the plots by gravity. One of the main problems with these systems is erosion, which is a by product of the erosive forces of water over the row, which brings soil loss and therefore decreases in crop yield. Erosion is the removal of surface soil material caused by...

vegetation deterioration is a main cause of erosion and land degradation. therefore, land cover reclamation in the effected areas will affect erosion trend. in reclamation projects, the investigation of relationship between the planted species and soils is highly recommended. atriplex species can sequester carbon into soil, and have an ability to conserve soil and prevent soil erosion, as well....

Soil erosion rates and soil quality indicators were measured along two hillslope transects in the Loess Plateau near Yan'an, China. The objectives were to: (a) quantify spatial patterns and controlling processes of soil redistribution due to water and tillage erosion, and (b) correlate soil quality parameters with soil redistribution along the hillslope transects for different land use manageme...

Soil degradation implies a decline in the capacity of the soil to perform environmental regulatory functions and yield agricultural goods. Soils are affected by regressive and/or degradative evolution processes as a result of natural causes as well as anthropogenic influences in semi-arid regions such as Central Spain. The main aim of this work is to evaluate the capacity of hyperspectral HyMap...

soil erosion is a main hazard in most area of the country specially in arid and semi-arid regions and itis very important because of sedimentation, pollution, increased flooding and its negative effects onsoil productivity. one of the features of arid and semi-arid areas is the presence of low cover ofvascular plants. these empty spaces are usually good niches for biological soil crusts or cryp...

[1] To determine the location of the potential dust source regions and to evaluate the dust emission frequencies over the arid and semiarid areas of China and Mongolia (35.5 N–47 N; 73 E–125 E), we established a map of Z0 from the composition of protrusion coefficient (PC) derived from the POLDER-1 bidirectional reflectance distribution function (BRDF). Using a =4 =4 resolution Z0 data set, we ...
