The Study of Biological Soil Crust (Mosses) Roles in Protection of Surface Soil in front of Water Erosion (Case study: Rangelands around Torogh Dam in Khorasan Razavi Province)

Fariba Alavizadeh; Kamalledin Naseri; Ali Golkarian; Ali Tavili

Volume 67, Issue 1 , May 2014, , Pages 83-92


  Soil erosion is a main hazard in most area of the country specially in arid and semi-arid regions and itis very important because of sedimentation, pollution, increased flooding and its negative effects onsoil productivity. One of the features of arid and semi-arid areas is the presence of low cover ...  Read More

Comparison of Infiltration Rate in Bare Soil and Ring-shaped Growth Pattern of Iris songarica and Scripoides holoschoenus species and Evaluation of Green-Ampt and Horton Infiltration Models

Asghar Mosleh Arani; Hamidreza Azimzadeh

Volume 65, Issue 2 , September 2012, , Pages 245-256


  Plant cover is one of the most important factors affecting infiltration rate of water into the soil and decreasing runoff. Distribution of plants in arid and semi-arid areas is almost patchy and form different patterns. One of the fascinating patterns is ring-shaped growth pattern. Ring patterns of varying ...  Read More

Application of GIS for calculation of runoff (Case study: Kechik Watershed, Golestan province)

N. Noura; A. Kabir

Volume 62, Issue 1 , June 2009, , Pages 153-166

  In this paper the utilization of GIS for the parameterization of rainfall- runoff process, physically based hydrological model components is described. The hytrogeneity of soil and vegetation in a catchment can be expressed with distribution functions of infiltration and soil storage capacities which ...  Read More
