Seasonal Precipitation Variability and Gully Erosion in Southeastern USA

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...

Gully Erosion in Southeastern Nigeria: Role of Soil Properties and Environmental Factors

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...

Investigation 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...

Evaluation of Precipitation Products of TRMM Satellite in Precipitation and Erosion Rate Monitoring across Iran

Extended abstract 1- Introduction     In order to calculate the erosive power of rainfall, high-resolution precipitation data are necessary for rainfall erosion evaluation. However, collecting the required data on kinetic energy of the rainfall particles and precipitation rates with short-term temporal resolution is a time-intensive task, particularly in developing countries, and the collecte...
