Comparative Study Between Satellite and Ground-based Drought Indices Using Change Vector Analysis Technique (Case Study of Kermanshah Province)

sajjad ebrahimzadeh; javad bazrafshan

Volume 27, Issue 5 , November and December 2014, , Pages 1034-1045

https://doi.org/10.22067/jsw.v0i0.20985

Abstract
  Drought can affects by reduced water resources, agricultural productivity, change in vegetation cover, and accelerate the desertification of areas. In order to drought monitoring, we need to quantify drought effects by using drought indices. These indices based on type of available data are divided ...  Read More

The Prediction Possibility of Soil Cation Exchange Capacity by Using of Easily Accessible Soil Parameters

A. Hezarjaribi; F. Nosrati Karizak; K. Abdollahnezhad

Volume 27, Issue 4 , September and October 2013, , Pages 712-719

https://doi.org/10.22067/jsw.v0i0.28092

Abstract
  Cation Exchange Capacity (CEC) is an important characteristic of soil in view point of nutrient and water holding capacity and contamination management. Measurement of CEC is difficult and time-consuming. Therefore, CEC estimation through other easily-measurable properties is desirable. The purpose ...  Read More

Kh. Ghorbani

Volume 26, Issue 3 , July and August 2012

https://doi.org/10.22067/jsw.v0i0.14943

Abstract
  So far several methods have been developed for mapping and interpolation of isohyets.one of the recently accepted methods is geographically weighting regression which is suitable for evaluation of spatial heterogeneity of dependent variable by using local regressions. In order to evaluate annually precipitation ...  Read More

Comparative Study of the Meteorological Drought Indices (Spi and Siap) Using Data Mining Method (Case Study of Kermanshah Province)

Kh. Ghorbani; A. Khalili; S.K. Alavinezhad; Gh. Nakhaezadeh

Volume 24, Issue 3 , July and August 2010

https://doi.org/10.22067/jsw.v0i0.3605

Abstract
  Abstract Precipitation is an important variable which is used in definition of drought. Based on precipitation amounts, some indices are devised for drought monitoring including, the Standardized Precipitation Index (SPI) and the Standard Index of Annual Precipitation (SIAP). Each of these Drought indices ...  Read More
