چکیده
The research aims to monitor environmental changes and study the state of desertification in northeastern part Al-Najaf province, Iraq. area suffers from drought phenomena. Remote sensing systems "RS" geographic information "GIS" are essential for monitoring because they provide Earth observation satellites that contribute detecting changes. Two Sentinel 2 images were acquired on December 26, 2015, November 29, 2021. combined used indices calculations. Normalized vegetation difference index "NDVI,” "NDWI," soil exposure "BSI," "NDBI." results showed extent began increase during period. Also, change detection became very dry, especially western part, suffering dunes, barren land, a lack water sources, area.

Assessing Geomorphologic Changes of the Mehran River Delta using Remote Sensing and GIS (Bandar Lenga, Hormozgan Province)
Delta areas are dynamic features with changes occurring at many spatial and temporal scales due to catastrophic events. Change detection and providing a fluvial map of changes are the main requirements for environmental and zonal planners in many studies. Geomorphic changes such as temporal and periodic changes in riverbeds are common events in all delta areas. The Mehran river delta is located...

Extended abstract 1- Introduction Coastal environments are one of the most sensitive environmental systems under the influence of dominant hydrodynamic processes. Coastal changes and evolution are occurring very fast. Coastal areas are now gradually becoming known as severe natural and man-made disturbances, including sea levels rising, coastal erosion and sedimentation, and over-exploitat...
متن کاملThe Impact of Land Use/Land Cover Changes on Groundwater Resources Using Remote Sensing & GIS (Case Study: Khan-Mirza Plain)
Hydrological status and water table fluctuations are directly related to land use and/or land cover (LULC) changes in each area. In this research, the impact of LULC changes on groundwater quantity and quality of Khan-Mirza Plain, in the northern Karun watersheds, was investigated. For this purpose, Landsat 5, 7 and 8 satellite images and ETM and OLI sensors were employed to prepare the L...
متن کاملDetecting land cover changes through remote sensing and GIS techniques
This note concerns the updating of the land cover map of the Arno River basin (9.000 km) developed in the frame of a research project aimed at landslide risk assessment. The land cover map has been produced through the analysis of panchromatic/multispectral Landsat ETM+ images and TERRA-ASTER data; those data were integrated and compared with B/W and color ortho-photos. To improve photointerpre...
