Salinity systems are well known as extreme environmental that occur either naturally or by certain human activities, in arid and semiarid regions, which may harm crop production. Soil salinity identification is essential for soil management reclamation projects. Information derived from space data acquisition (e.g., Landsat, ASTER) considered one of the most rapid techniques mapping Salt-Affected (SAfSoil). The current study tested previously proposed indices on northern Nile Delta region,...

Abstract Remote sensing data and digital elevation models were utilized to extract the catchment hydrological parameters delineate storage areas for Ugandan Equatorial Lakes region. Available rainfall/discharge are integrated with these morphometric construct a model that simulates water balance of different interconnected basins enables impact potential management options be examined. The total annual discharges generally very low (less than 7% rainfall). basin shallow (5 m deep) Lake Kioga...

Abstract The Fawakheir-Attala gold mining zone in Egypt’s Central Eastern Desert features a diverse range of rock formations, including Precambrian crystalline rocks and Phanerozoic sedimentary formations. These formations encompass gneisses, metavolcanics, metasediments, metagabbro-diorite complex, Dokhan volcanic rocks, granitic alongside lower upper Nubia sandstones. Faults shear zones are pivotal controlling mineralization within the area, indicative substantial mineral wealth. This...

This paper assesses impact of the Renaissance Dam on Ethiopia; Nile discharge ultimately reaches Egypt downstream. The Landsat-8 satellite images 2013 were obtained and interpreted to identify locations for construction sites Dam. Then Shuttle Radar Topography Mission (SRTM) data processed create a digital elevation model (DEM) Blue upstream areas that will be submerged. Different scenarios dams' heights resulting storages simulated estimate abstraction flows until completion project annual...

Fine particulate matter (PM2.5) can penetrate deeper into the respiratory systems and cause various health problems. In this paper satellite-derived PM2.5 concentrations, which provide better spatial coverage in form of satellite-imageries are used to analyse temporal distributions Saudi Arabia. concentrations (μg/m3) estimated using relationship between Aerosol Optical Depth (AOD) from satellite images, such as those Moderate Resolution Imaging Spectroradiometer (MODIS). varied both...

This paper aims to quantify the hydrological parameters for flash flood event of 17th January 2010 in Sinai using multiple sets remote sensing data and field work nongaged catchments (approximately 2100 sq km) wadis affecting Ras Sudr area, which is heavily occupied by numerous oil fields related activities. The affected areas were visited, several cross sections main active channels surveyed estimate peak discharge rates. Tropical Rainfall Monitoring Mission (TRMM) have been used rainfall...

Pan-African basement rocks cover the study area along boundary between Central and Southern Eastern Desert with small exposed sedimentary sequences. Several vein-type gold mineralization hydrothermal alteration zones have long been known in area. Aeromagnetic remote sensing imagery data were integrated for mapping structural elements related to mineralization. By aeromagnetic inspection, complexity porphyry intrusions density maps effectively constructed by applying Enhanced Center...

Band rationing, principal component analysis (PCA) and decorrelation stretch (DS) techniques of Landsat-8 with Sentinel-2 data successfully used in the discrimination lithological units surface structure features Wadi Al-Miyah area Central Eastern Desert Egypt. The Advanced Spaceborne Thermal Emission Reflection Radiometer (ASTER) were processed to identify hydrothermal mineralized alteration zones related radioactive minerals. Airborne gamma-ray spectrometry (AGRS) has been determine...

Saudi Arabia is of a limited water resources due to its sporadic and rainfall. During the last two decades, rapid development country, together with increased population living standards, resulted in drastic changes needs irrigated agriculture consuming highest amount (about 88%). The current study uses prototype system monitor crop consumption at Wadi Uranah area, Makkah. relies on use available satellite images (Landsat 8 Sentinel-2) extract required parameters needed calculate for...

The Oligo-Miocene basaltic exposures at Wadi Abu Qada – Wata area, west-central Sinai Peninsula occur as intra-continental fissure-fed eruptions in the form of km-scale sill attaining thickness about 30 m and dyke 70 thick, intruding/extruding Early Cretaceous to Eocene sedimentary sequences. Stratigraphy study area was dealt with context geologic setting these basalts, which are genetically related Gulf Suez rifting late Oligocene. These were discriminated from their surrounding rocks using...

The initial phase of the Gulf Suez rifting in late Oligocene was accompanied by eruption continental basaltic magmas, which continued to early Miocene. Within rift zone at Abu Zenima area, west-central Sinai, several km-scale Oligo-Miocene exposures form dykes, sills and lava flows intruded/extruded Phanerozoic sedimentary successions. These outcrops were successfully discriminated from their country rocks remote sensing techniques, using Landsat-8 dataset. basalts are evolved tholeiitic,...

The shear zone characterization is a substantial task for understanding the influencing tectonic movements. In this study, an integrated approach of remote sensing and aeromagnetic data introduced to imagine trace subsurface between Central (CED) Southern (SED) domains Egyptian Eastern Desert in comparison with previously proposed approaches mainly using only surface criteria. To produce enhanced geological map reflecting different lithological units along both sides surficial zone,...
