ADVANCES IN SOIL SALINITY DETECTION IN ARID AND SEMI- ARID REGIONS USING SALINITY AND VEGETATION INDICES

Trend analysis and detection of precipitation fluctuations in arid and semi-arid regions

The most important impacts of climate change relate to temperature and precipitation. Precipitation is particularly important, because changes in precipitation patterns may lead to floods or droughts in different areas. Also, precipitation is a major factor in agriculture and in recent years interest has increased in learning about precipitation variability for periods of months to annual and s...

Drought Detection and Quantification Using Field-based Spectral Measurements of Vegetation in Semi-arid Regions

Investigating the interaction between rivers and sand dunes in arid and semi-arid regions of Iran

Extended abstract 1- Introduction Fluvial and aeolian processes are important factors in changing the surface of morphology in the Earth. When rivers and sand dunes meet, the transportation of sediment  between them can lead to one of the systems or both  of them change. With their connection between river sediment and wind systems there would be lots of reactions, but very little has been st...

extraction of soil salinity zone in arid and semi arid regional using of remote sensing data (case study: darab township)

introduction soil salinity and expansion tts it, in the arid and semi-arid areas is including environmental issues that in recent years attention has been due to population growth and the need to utilizeland. in order to human was tried that using of different techniques determined salinity area between remote sensing data in recent years have provided relatively accurate results as a source of...

Evaluating different spectral indices in identification and preparation of soil salinity mapping of arid region of Iran

Soil salinity undergoes significant spatial and temporal variations; therefore, salinity mapping is difficult, expensive, and time consuming. However, researchers have mainly focused on arid soils (bare) and less attention has been paid to halophyte plants and their role as salinity indicators. Accordingly, this paper aimed to investigate the relationship between soil properties, such as electr...
