Mapping Spatial Variability of Soil Salinity Using Remote Sensing Data and Geostatistical Analysis: A Case of Shadegan, Khuzestan
Extended abstract 1- Introduction Soil salinity is one of the most important desertification parameters in many parts of the world. Thus, preparing soil salinity maps in macro scales is necessary. Water and soil salinity as one of the contributing parameters in desertification, cause soil and vegetation degradation. Soil salinization represents many negative effects on the earth systems such ...
متن کاملMapping spatial variability of soil salinity in a coastal area located in an arid environment using geostatistical and correlation methods based on the satellite data
Saline lakes can increase the soil and water salinity of the coastal areas. The main aim of this study is to distinguish the characteristics of the spectral reflectance of saline soil, analyze the statistical relationship between soil EC and characteristics of the spectral reflectance of saline soil, and to map soil salinity east of the Maharloo Lake. The correlation between field measurements ...
متن کاملمطالعه تغییرات مکانی شوری خاک در منطقه رامهرمز (خوزستان) با استفاده از نظریه ژئواستاتیستیک 1- کریجینگ
This study addresses the methodology of studying spatial variability of soil salinity. The information used is based on a semi-detailed soil survey, followed by a free survey, conducted in Ramhormoz, Khuzestan. The study of soil salinity variations was carried out using about 600 sampling points with an average distance of 500 m, at three depths of 0-50, 50-100, and 100-150 cm. To determine the...

متن کاملDetecting salinity in early stages using electromagnetic survey and multivariate geostatistical techniques, A Case study of Nong Suang district, Nakhon Ratchasima, Thailand
Detecting salinity in early stages using electromagnetic survey and multivariate geostatistical techniques. This research is aimed at increasing the accuracy of detecting soil salinity in early stages of the process. This phenomenon develops at depth; optical remote sensing (e.g. satellite images) cannot be useful in detecting subsoil variability. Therefore Electromagnetic (EM) survey, using EM...
