The northwestern coast of Sinai is home to many economic activities and development programs, thus evaluation of the potentiality and vulnerability of water resources is important. The present work has been conducted on the groundwater resources of this area for describing the major features of groundwater quality and the principal factors that control salinity evolution. The major ionic content of 39 groundwater samples collected from the Quaternary aquifer shows high coefficients of variation reflecting asymmetry of aquifer recharge. The groundwater samples have been classified into four clusters (using hierarchical cluster analysis), these match the variety of total dissolvable solids, water types and ionic orders. The principal component analysis combined the ionic parameters of the studied groundwater samples into two principal components. The first represents about 56% of the whole sample variance reflecting a salinization due to evaporation, leaching, dissolution of marine salts and/or seawater intrusion. The second represents about 15.8% reflecting dilution with rain water and the El-Salam Canal. Most groundwater samples were not suitable for human consumption and about 41% are suitable for irrigation. However, all groundwater samples are suitable for cattle, about 69% and 15% are suitable for horses and poultry, respectively.
Water resources management is considered a major socio-economic issue and a central component for future development; this implies an increasing demand for exploration of groundwater of high potentiality to cope with the excessive needs. In this work, Analytic Hierarchy Process (AHP) which is a widely used Multi-Criteria Decision Analysis (MCDA) has been used with Geographic Information System and Remote Sensing for classifying and mapping zones that intrinsically control and reflect groundwater recharge potentiality in the western area of El Minia Governorate, Upper Egypt. Six parameters of high attributes to groundwater recharge potentiality (Geology, Geomorphology, Slope, Lineaments Density, Drainage Density, and land use/land cover) have been selected. Assigned weights based on their relative importance to groundwater recharge, the weights were compared in a pair-wise matrix, the Eigen values were determined and the consistency ratio was calculated to validate the assigned weights; the ranges of these parameters are classed and rated. Overlay analysis was done to integrate the thematic layers of the parameters in Arc GIS domain for the development of a groundwater recharge potential map which has been verified using stable isotopic content (δ 18 O and δD) of 67 groundwater samples collected from the study Physico-Chemical and Organolyptical Characteristics Of Cake Fortified By Irradiated Broccoli (Brassica Oleracea L.Var Italica) Powder ( 15 )
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
