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 کاملmodeling gully erosion in dyreh catchment
there are technical and theoretical knowledge of the gully, ditch the clean areas on topographic maps and digital models that will help. however, the ability to use maps (dem) to identify the location and frequency of gully requires knowledge about the process of creating a moat.the present study modeled gulliation prone areas in dyreh river basin done. materials and methods used in this resear...
