Soil erosion is one of the major environmental problems in terms soil degradation Shirvan plain Republic Azerbaijan. leads to significant on- and off-site impacts such as decrease productive capacity land sedimentation. The key aspects influencing quantity mainly rely on vegetation cover, topography, type, climate. This research studies quantification under different levels data availability pl...
Soil structure and its change are good indicators for soil quality environmental stability, land-use is known to be an important factor that affects structure. We investigated the seasonal temporal variability in evaluated erodibility under different land-management practices Mollisols region of Northeast China. considered five modes sloping land (5°), i.e., bare (BL), natural vegetation restor...
Grupi and Kashkan marl formations comprise a considerable part of Zagros region. These formations have a considerable erodibility and sedimentation potential because of their special geological and mineralogical characteristics. The objective of this study was to compare the erosion and sediment yield of Kashkan and Grupi formations in Merk watershed located in southeast Kermanshah, using the M...
Rainfall simulation experiments on road batters in a forest catchment in New South Wales, Australia, demonstrated the limits of small scale erosion studies. Comparable erodibility studies were carried out on road surfaces, road batters constructed of soil, bedrock and unconsolidated materials and the forest surfaces. There was no significant difference in sediment loss between any type of site,...
Soil erosion and sediment yield from watersheds confine sustainable use of land resources and is supposed as one of the most critical environmental issues. Prediction of storm wise soil erosion and sediment yield is very important, especially in arid and semiarid regions due to small number of events and high intensity of rainfall. Evaluation of soil erosion by existing models is needed as an i...
Ecosystem services are benefits that people obtain from ecosystems. Soil retention is one of the most important ecosystem services. The capacity of ecosystem to maintain soil can be estimated by quantifying this services. In this study, version 3.0.0 of the InVEST software was used to map this ecosystem service in the eastern part of Gorgan-Rud watershed. The InVEST model employs the Universal ...
