Assessment of Environmental Impact On, Wadi El-Natrun Depression Lakes Water, Egypt
Assessment of environmental Impact was established to provide and evaluated the background picture of water quality of Wadi El-Natrun depression Lakes water. Physico-chemical characteristics (air and water temperatures, electrical conductivity (EC), total solids (TS), total dissolved solids (TDS), total suspended solids (TSS), salinity, pH, dissolved oxygen (DO), chemical oxygen demand (COD), C...
متن کاملAssessment of the renewable groundwater resources of Wadi El-Arish, Sinai, Egypt: modelling, remote sensing and GIS applications
Recharge of the alluvial aquifers flooring Wadi El-Arish in central and northern Sinai, Egypt was investigated. A hydrological model that combined the spatial and temporal distribution of rainfall, suitable infiltration parameters, and appropriate sub-basin unit hydrographs to estimate rainfall excess, transmission losses along stream networks, and downstream runoff was developed. The Wadi El-A...
متن کاملTerrestrial fungi tolerating the hypersaline water of Wadi El-Natrun Lakes, Egypt
Chemical analysis revealed that water samples collected from Wadi El-Natrun Lakes were highly alkaline, of pH ranging from 8.4 –9.5 and of high levels of total soluble salts, chlorides, sodium and potassium. Water collected from El-Zugm Lake showed the highest levels of organic matter, sodium, calcium, magnesium and chlorides among the 8 lakes investigated. On the other hand, some parameters sh...
متن کاملDroughts & Floods Assessment and Monitoring Using Remote Sensing and Gis
Space technology has made substantial contribution in all the three phases such as preparedness, prevention and relief phases of drought and flood disaster management. The Earth Observation satellites which include both geostationary and polar orbiting satellites provide comprehensive, synoptic and multi temporal coverage of large areas in real time and at frequent intervals and ‘thus’ have bec...
متن کاملProfile of Some Trace Elements in the Water - Surficial Sediment of Wadi El-Natrun Depresion Lakes, Egypt
Profiles of some trace elements (Fe Mn, Zn, Cu, pb and Cd) were detected in saline water and surficial sediment of Wadi El-Natrun depression lakes. The trace elements concentrations largely indicate the influence of weathering of terrigenous sources on land. The order of the studied trace elements in brine lakes of Wadi El-Natrun from high to low concentrations are Mn > Pb > Fe > Zn > Cu > Cd a...
