Phosphorus losses from arable land need to be reduced to prevent eutrophication of surrounding waters. Owing to the high spatial variability of P losses, cost-effective countermeasures need to target parts of the catchment that are most susceptible to P losses. Field surveys identified critical source areas for overland flow and erosion amounting to only 0.4-2.6 % of total arable land in four d...

Negative impacts of gully erosion in marly areas are severe due to improper landuse practices such as irrigation, tillage, overgrazing and degradation of vegetation cover. The objective of this research was to evaluate gully thresholds related to plant vegetation cover and landuse change in the Agriculture (AG), Fair Rangeland (FR) and Weak Rangeland (WR) areas of Ghaasr-e-Shirin, Kermanshah, I...

Considering the linear erosion processes in river basins slopes it can be noticed that gully is most intensively changing relief, leading to complete soil cover destruction, and making land not suitable for agricultural use. The latest maps of gullies'development Russia were compiled more than 50 years ago seen as very outdated. Since time no comprehensive gullies network mapping has been carri...

Abstract Loess Plateau provides a broad growing environment for crops. However, due to the loose soil, soil erosion is serious. Gully Consolidation and Highland Protection key work in construction of ecological civilization Plateau. Using method simulating Protection, terrain conditions are changed, hydrological model used simulate change before after ditch head landfill. In this paper, Yangjia...

Desertification process as a great problem affects most of the countries in the world specially developing countries. This process has a high rate in arid and semi-arid countries such as Iran. The main objective of this research was to investigate land degradation status and desertification mapping of Kashan area. Different studies have been carried out in the world in order to assess desertifi...
