Review of the integrated groundwater and surface‐water model (IGSM)
Development of the finite‐element‐based Integrated Groundwater and Surface‐Water Model (IGSM) began in the 1970s. Its popularity grew in the early 1990s with its application to California's Central Valley Groundwater Surface‐Water Model in support of the Central Valley Project Improvement Act. Since that time, IGSM has been applied by federal, state, and local agencies to model a number of major basins ... Read more

Hydrochemical evolution and variation of groundwater and its environmental impact at Sohag, Egypt
Groundwater resources of Sohag, Egypt are currently threatened by contamination from agricultural and urbanization activities. Groundwater in Sohag area has a special significance where it is the second source for fresh water used for agricultural, domestic, and industrial purposes. Due to growing population, agriculture expansion, and urbanization, groundwater quality assessment needs more attention to cope with the increasing water demand ... Read more

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

Effect of water–rock interaction processes on the hydrogeochemistry of groundwater west of Sohag area, Egypt
Groundwater is used intensively for land reclamations and domestic purposes in new reclaimed areas west of the Nile Valley in Sohag Governorate, Upper Egypt as it is the only source of water in the area. Twenty-six groundwater samples are collected to evaluate the hydrochemical characteristics and the impact of water–rock interaction on the chem-istry of groundwater using classical geochemical and ...
