Modelling seasonal variation of gully erosion at the catchment scale

modeling 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...

Soil erosion and reservoir siltation at catchment scale

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...

Integrated Water Allocation-Economic Modelling at a Catchment Scale

Rapid economic and population growth has led to increased demand for water from the industrial and domestic sectors and put pressure on resources available for agricultural production. With growing scarcity and increasing inter-sectorial competition for water the need for efficient and sustainable water allocation policies has also become more important. Finding ways to meet this growing demand...

The 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...
