The present study aims to develop an efficient predictive model for groundwater contamination using Multivariate Logistic Regression (MLR) and Random Forest (RF) algorithms. Contamination by ammonia is recorded by many authors at Sohag Governorate, Egypt and is attributed to urban growth, agricultural, and industrial activities. Thirty-two groundwater samples representing the Quaternary aquifer are collected and analyzed for major cations (Ca, Mg, and Na), ammonia, nitrate, phosphate, and heavy metals. Lead, magnesium, iron, and zinc variables are used to test the model with ammonia which is used as an index to the groundwater contamination. Spatial distribution maps and statistical analyses show a strong correlation of ammonia with lead and magnesium variables whereas iron and zinc show less correlation. For Random Forest (RF) model, the data is divided into 70% training and 30% testing subsets. The performance of the model is evaluated using the classification reports, and the con...

The Quaternary aquifer has a special significance in Akhmim district, Upper Egypt, especially during the dry seasons, when surface water resources are insufficient and limited. In Akhmim district, the population mainly depends on groundwater for drinking, especially in spontaneous residential areas and inside agricultural lands. Therefore, assessing the groundwater quality is necessary to reduce diseases resulting from using polluted water in drinking. The Weighted Arithmetic Water Quality Index (WAWQI) was used for evaluating the groundwater quality, and it was classified according to the Egyptian and WHO standards and based on fifteen measured physicochemical parameters (TDS, Na, Cl, Ca, pH, Mg, NO3, SO4, TH, Cr, Cu, Fe, Pb, Mn, and Zn). To investigate the spatial distribution of WAWQI in Akhmim district, the spatial analyst tools (IDW method) were used. The WAWQI results showed a great diversity in groundwater viability for drinking due to the exposure of groundwater to many sour...

Beni Suef governorate is one of highly population density areas in northern Upper Egypt. The surface water in Beni Suef district suffer from pollution due to the impact of anthropogenic activities such as usage of fertilizers and pesticide, waste disposal, industrial wastes and wastewater. The present study aims to estimate the Water Quality Index (WQI) and concentration of some other parameters through applying water quality estimation models based on Remote Sensing techniques applied on Landsat 8 OLI satellite images. Thirty-four points distributed among the study area are used for the analysis and to compare the data with the results obtained from analyzing water samples tested in the laboratory to investigate the feasibility of utilizing remote sensing data to identify water quality. In the present study, integrated technologies of remote sensing and water quality have been successfully utilized to assess water.

Giza Pyramids Plateau is recognized as one of the most unique archaeological sites in the world and it was recently declared as one of the most iconic travel spots on the planet. During the last three decades, the rise of groundwater levels in Greater Cairo has become a severe problem threatening the existing and recent buildings. The main aim of this research is to assess the groundwater movement at Giza Pyramids Plateau through an integrated groundwater and GIS platform. The main inputs include groundwater quality, groundwater level and depth to groundwater. GIS is used as a tool to assess the groundwater flow pattern in the buffer zones based on the UNESCO classification. It could be observed that all areas witnessing a rise in the water level are located within the transition zone around the pyramids. Sphinx area has several recharge sources due to leakage of sewage water, seepage from canals and vertical percolation from irrigation water especially that it is located in a relat...

Abstract Urban sprawl is one of the major problems that evolved in the Nile Delta as a result of the deficiency in the security system after the 25 th of January revolution in Egypt in 2011. This problem not only threatens the limited fertile lands but also influences the water distribution regime in these areas. For this purpose, three types of satellite images were employed; i.e. Landsat Thematic Mapper (TM) 1990, Egyptsat-1 2010 and SPOT 5–2011, to study the urban sprawl and its impact on the agricultural land and water distribution management in Gharbia Governorate. Maximum likelihood supervised classification and post classification change detection techniques were applied for monitoring the urban sprawl in this study area. The accuracy of the classification results ...

Remote sensing is the science and art used to collect, organize, and analyze reasonable information about a specific phenomenon, pattern, or region without direct or physical contact with the study area. In Egypt, the development of remote sensing has recently been supported, maintained, and widened via various research projects, which have been sponsored and funded by national and international organizations. These collaboration projects have been applied in various fields such as agriculture, coastal management, hydrology, ecology, meteorology, geoarchaeology, and geology. The research areas also included geography, environmental monitoring, and flood prediction. Accordingly, this chapter summarizes the recent applications of remote sensing in Egypt regarding (a) the number, types, and objectives of published documents, (b) the academic, industrial, governmental, and non-governmental sponsors, and (c) the institutions, laboratories, and research centers.

Abstract Dakhla Oasis is located in the heart of the Western Desert of Egypt 190 km to the West of the Kharga Oasis where it contains highly fertile lands rich in water and it supports a higher population compared to the Kharga Oasis. The study area is mainly concentrated in the Rashda village where Well No. 3 Irrigation District is located to the northwest of the village. Satellite imageries of Landsat Thematic Mapper (TM) 1972 and 1984, Landsat Enhanced Thematic Mapper (ETM+) 1988, and Shuttle Radar Topography Mission (SRTM) 2000 were used to determine the change in landuse and change in elevation with its relation to landuse. The automated unsupervised classification technique was applied to delineate the different landuse classes. Landsat – 5/TM and Landsat – 7/ETM + images in the period between 2001 and 2010 have been used to study crop rotation at the Rashda village to detect the amount of vegetation cover and its condition in the Well No.3 district. The land use change analysis showed that the extension of cultivated land was already completed by the 1980s in the North and South subdistricts, after which it spread toward the West. Because the altitude in the West subdistrict is lower than the wells, irrigation water could be distributed adequately if the condition of the irrigation channel was well maintained. The relationship between the irrigation level and plant production was not favorable in the West compared with other subdistricts. The cultivated area in the West district has been increasing since the 1970s. According to the crop rotation analysis, the different productivity of the subdistricts was caused by several factors, including the land altitude and the distance from the well, as well as other factors such as social relationships in the village.

The Egyptian government is showing a great interest on the lateral population extension in the deserts. Accordingly, a number of roads were constructed. Sohag – Safaga new highway in the Eastern Desert that connects the Nile Valley with the Red Sea is an example of such roads. A number of developmental extensions have been proposed aligning roads including agricultural, urban, industrial, touristic, and commercial projects. These extensions need different studies concerning their sustainability to protect them from any hazard that may act on them and to make use of the available natural resources that are required for development. These natural resources include engineering construction materials, soil for agriculture, surface and subsurface water resources, and mineral wealth. The study area is characterized by different geomorphological units: mountains belts, sandstone and limestone plateaux, wadi terraces, wadi bottoms, alluvial fans, out wash plains, sand sheets, sand dunes, an...
