Gully Erosion after Wildfire
Predicting runoff and erosion from watersheds burned by wildfires requires an understanding of the spatial structure of both hillslope and channel drainage networks. We investigate the small-scale and large-scale structures of drainage networks using field studies and computer analysis of 30-m digital elevation model. Topologic variables were derived from a composite 30-m DEM, which included 14...
متن کاملThe Gully Erosion Effect On the Environment
The paper contains data about the destructive effects of gully erosion on the environment. It provides general information about the gully erosion in several countries around the world including Romania and is considered a case study for a river basin located in the Semenic Mountains (Bârzava drainage area). The case study is based on the following assumptions: the presence of different types o...
متن کاملInvestigation of Some Methodologies in Providing Erosion Maps of Surface, Rill and Gully and Erosion Features
Some methodologies were compared in providing erosion maps of surface, rill and gully and erosion features, in research which took place in the Varamin sub-basin, north-east Tehran, Iran. A photomorphic unit map was produced from processed satellite images, and four other maps were prepared by the integration of different data layers, including slope, plant cover, geology, land use, rocks erodi...
متن کاملImpact assessment of soil Physio-chemical properties on the development of the gully erosion
Extended abstract Introduction Water erosion has been a problem worldwide, which causes the phenomenon of land degradation in semi-humid areas of dry land. The risk of soil erosion in arid and semiarid areas, especially in mountain ranges is of significant cases in land use planning. Soil erosion in these areas is one of the important consequences of climate change, or in general, the ob...
متن کاملDetermining the Factors affecting on the geometry of Gully Erosion (Case study: Darrehshahr, Ilam)
One of the types of water erosion and land degradation which causes imbalance in the area of natural resources and agricultural land and gives heavy losses, is the gully erosion phenomenon. To control this phenomenon, It is important to understand the influence factors on the geometry specification. Land degradation, a broken ecological balance of the land and landscape and risk of falling at b...
