Runoff Estimation Using Artificial Neural Network Method
Volume 6, Issue 4 , October 2014

Abstract
  Runoff is one of the major components of calculating water resource processes and is the main issue in hydrology. Many concept models are used to predict the amount of runoff, which in most cases depend on topographical and hydrological data. Conventional models are not appropriate for areas in which ...  Read More

Object based Classification of Large Scale Satellite Images from Complicated Urban Areas for Land Cover Map Production based on a New Hierarchical Model
Volume 6, Issue 4 , October 2014

Abstract
  Land cover information is one of the most important prerequisite in urban management system. In this way remote sensing, as the most economic technology, is mainly used to produce land cover maps. Considering the complicated and dense urban areas in third world countries, object based approaches are ...  Read More

Power Transmission Line Routing Using NSGA-II Algorithm
Volume 6, Issue 4 , October 2014

Abstract
  Using new approaches to optimize the process of power transmission line routing can solve many complex problems which power transmission line routing decision-makers are faced. Due to the expansion of involved parameters we can consider multi-objective evolutionary algorithms as appropriate method in ...  Read More

Modeling of Livestock Drinking Water Sources Capabilities Using GIS in Taleghan Region, Alborz Province
Volume 6, Issue 4 , October 2014

Abstract
  A primary uses from Iran rangelands is livestock grazing and the major livestock is sheep. Sheep grazing on the slopes above 60%, because of using a lot of energy for grazing operation, caused to not only reduces livestock performance but also increases the risk of erosion. Sheep grazing in an area where ...  Read More

The Application of Geostatistical and GIS Techniques in Locating Suitable Areas for Irrigation Systems in Arid Regions
Volume 6, Issue 4 , October 2014

Abstract
  The importance of groundwater as a source of water supply in arid, semi –arid areas in recent years due to the uncontrolled exploitation of groundwater have been doubled. Uncontrolled exploitation has been caused a drop in the water table in many areas of the country, including this region. With replace ...  Read More

Determination of Soil Physical and Chemical Factors on the Differentiation of Kavir Facies based on the Geometric Average and the Aggregation Methods of ASTER Image Data
Volume 6, Issue 4 , October 2014

Abstract
  Accurate mapping of geological structures play an important role in the land management, some of which are considered as the origination of wind deposits, dust and aerosols. During the last decades, remote sensing has considerably helped the studies of desert areas especially in change detection of land ...  Read More

Developing a Cellular Automata Model for Urban Growth
Volume 6, Issue 4 , October 2014

Abstract
  In the last decade, cellular automata models have been widely used for simulation spatial phenomena; however, exact nature of these models have been lead to various limitations for essential simulation of these phenomena. In this research, traditional cellular automata models have been developed through ...  Read More
