Effect of topographic threshold conditions for gully head development in different use (Case study: Boushehr province)

Gholm Reaza Rahi; A Kaviyan; K Soleimani; H Pourghasemi

Volume 74, Issue 1 , June 2021, , Pages 69-81


  Creating a gully is a reaction to the geomorphologic conditions, this type of erosion extends over a wide range of environments, and the threshold of topography is related to the slope and drainage level and Controls the position and expansion of gullies in different uses. The slop-area equation as a ...  Read More

A Study on the Topographic Threshold and Effective Factors on Sediment Production and Gully Development in Neyriz,Fars Province

S.M Soleimanpour; majid Soufi; hassan Ahmadi

Volume 63, Issue 1 , June 2010, , Pages 41-52

  Gully erosion has an important role in Fars province due to sediment production and enormous damages to land, roads and infrastructures. In this research, 15 gullies were selected to measure their morphometric characteristics. The length, depth, top and bottom width and volume of gully erosion were then ...  Read More
