2018-09-23 20:10:57 Keywords Water management, Egypt, Groundwater, Water resources,
Overview of water resources and requirements in Egypt; the factors controlling its management and development
Egypt covers very arid regions situated between the Sahara and Arabian deserts. It is extremely dependant on the River Nile as the country hardly has any other fresh water resources. Rainfall is very rare, except for a very small trip along the coast of the Mediterranean. Fossil groundwater is available in parts of the Western and Eastern Deserts and Sinai. ... Read more

Multicriteria decision analysis based on analytic hierarchy process in GIS environment for siting nuclear power plant in Egypt
Due to increasing demand of electrical energy and freshwater in Egypt, it is safe to assume that the decision makers will turn to nuclear power as the feasible alternative for energy. However, as time goes by, fewer sites will be available and suitable for nuclear power plant development. Site selection is a key phase of the siting process of a ... Read more

Chemical characteristics and assessment of groundwater quality in Halayieb area, southeastern part of the Eastern Desert, Egypt
Halayieb area is located at the southeastern corner on the border between Egypt and Sudan. The area has very important strategic aspects to Egypt. Groundwater is the only source of fresh water in the area. The hydrogeochemical characterizations of groundwater in the area were carried out, to assess the quality of groundwater for its suitability for drinking and irrigation purposes. ... Read more

Using lithologic modeling techniques for aquifer characterization and groundwater flow modeling of the Sohag area, Egypt
Three dimensional lithologic modeling techniques have been used for detailed characterization and groundwater flow modeling of the Quaternary aquifer system of the Sohag area, Egypt. Well log data were used for building the lithologic model using RockWorks. A groundwater flow model, facilitated by MODFLOW 2000, was built using results of the lithologic model. The obtained lithologic model honored the well ... Read more

Using generic and pesticide DRASTIC GIS-based models for vulnerability assessment of the Quaternary aquifer at Sohag, Egypt
Groundwater resources in the Sohag area, Egypt are currently threatened by contamination from municipal and industrial activities, and agricultural pesticides. To cope with the growing population, there has been development in the desert zone on both sides of the Nile Valley including agricultural investment areas, wastewater disposal sites, new urban areas, and industry. Use of agrochemicals in the old cultivated ... Read more

Meandering and bank erosion of the River Nile and its environmental impact on the area between Sohag and El-Minia, Egypt
The present work deals with meandering and bank erosion of the River Nile of Egypt and its environmental impact between Sohag and El-Minia, Egypt. The study depends on using Landsat imagery acquired on 1987–2000 and field observations. Field observations, remote sensing, and GIS analysis and sinuosity index were used in this study to investigate river meandering and the associated processes ... Read more

2018-09-14 19:58:03 Keywords (Hepatocellular carcinoma (HCC, Egypt, Risk factors,
Hepatocellular Carcinoma in Upper Egypt: A Retrospective Study
Abstract Background: Hepatocellular carcinoma (HCC) is one of the leading causes of cancer deaths worldwide. The incidence of HCC is highest in Asia and Africa, where the endemic high prevalence of hepatitis B and hepatitis C strongly predisposes to the development of chronic liver disease and subsequent development of HCC. Aim of the Work: Our study was designed to characterize ... Read more

2018-09-14 16:38:08 Keywords Nitrates, Groundwater, Nile Valley, health impact, Sohag, Egypt,
ASSESSMENT OF NITRATES AND THEIR HEALTH IMPACT IN QUATERNARY GROUNDWATER AQUIFER OF SOHAG GOVERNORATE, EGYPT
The present study is destined to measure the nitrate levels of groundwater in Sohag Governorate aiming to determine their possible sources and evaluate their environmental and health impact. 17% of the analyzed samples have NO3-levels go over the MAL. Potentially harmful levels of NO3-exceeding nearly four times higher than the maximum allowable limit (MAL) for drinking water (45 mg/l) were ... Read more

2018-09-14 16:33:34 Keywords Landuse change, monuments, Luxor, Egypt,
Land use change and deterioration of Pharaonic monuments in Upper Egypt
Pharaonic monuments in Upper Egypt are currently threatened by environmental impacts including the rise of groundwater table, seepage of drainage and sewage water from cultivated lands and surrounding houses as well as salinity problems. These problems are mainly due to change of land use since construction of High Dam in 1968. land use changes include expansion of old cultivated lands, ... Read more

2018-09-14 16:31:02 Keywords Groundwater contamination, Quaternary aquifer, Qena, Egypt,
Degradation of groundwater quality of quaternary aquifer at Qena, Egypt
Qena area, Upper Egypt has a limited water resources represented by the River Nile, irrigation canals and groundwater resources. The Quaternary groundwater aquifer is the main water source in the study area. Urbanization and agricultural activities in the study area constitute the main pollution sources of groundwater. Pollution sources in the study area include mixing from wastewater and agrochemicals from ... Read more
