surface. the development of gullies causes the loss of a great amount of soil and could be considered as one of the principal causes of geo-environmental degradation. in this research fazi model introduced for gully erosion zonation in arid and semiarid area considered to calibration and validation in kahkiloeh and boyerahmad province. therefore, the abgandi watershed were selected by considera...
gully erosion is one of the most destructive types of channeled water erosion that removes aconsiderable volume of soil as it develops. this type of erosion consists of complex a geomorphicprocess that has been known as an indicator of accelerated soil erosion. in this research theadvancement of 25 headcuts were assessed through digital interpretation of multi-temporal aerialphotos, field obser...
Gully erosion is the most advanced water erosion in watersheds that produce large volumes of sediment can cause serious damage. In order to manage and cope with this type of erosion, to identify areas of high risk of gully erosion in the watershed is very important. For this purpose gully erosion hazard zonation maps by combining information layers of different factors affecting the formation o...

Extended abstract 1- Introduction Gully erosion is one of the most important sources of sediment in the watersheds and a common phenomenon in semi-arid climate that affects vast areas with different morphological, soil and climatic conditions. This type of erosion is very dangerous due to the transfer of fertile soil horizons, and the reduction of water holding capacity also is a factor for s...
Introduction Gully is one of the forms of water erosion features in many regions of the world. Gully erosion could produce abundant sediment load, reducing the fertility of land and destruction of structures. In literature, for the preparation of landslide susceptibility mapping, several studies have been conducted using logistic regression. But, a few authors focused on gully erosion suscep...
Dasht Yari plain is nearly 580,000 hectares which is under engraving gully erosion and unfortunately the gully development rate is increased in the recent decades. Satellite images may provide quick, extensive, and valuable information for the interpretation of morphometric characterstics of gully erosion expansion due to having attributes such as time series, relatively low cost, large coverag...
the problems of land degradation and soil loss are among the major problems of watersheds in iran. for erosion andsediment estimation one can use statistical and empirical methods. for doing this, land unit map and the map of effectivefactors should be prepared. for erosion and sediment estimation one can use statistical and empirical methods. however,these empirical methods are usually time co...
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...
