Utilizing the geological data and remote sensing applications for investigation of groundwater occurrences, West El Minia, Western Desert of Egypt

Abstract

West EL Minia area is considered one of promising areas for future development plans in Egypt. The current research provides an integrated remote sensing data, microfacies analysis, field studies and geochemical approach to investigate the groundwater resources in West El Minia area. Three aquifers were investigated; Oligocene sandstone, Middle Eocene limestone and Nubian sandstone aquifer. New data about two aquifers (Nubian sandstone and Oligocene) are presented in the current study extracted from well logging interpretation and wells rock samples. The groundwater of the Oligocene sandstone and Middle Eocene limestone aquifers are recorded under unconfined conditions, while the Nubian sandstone is recorded as confined aquifer. The total thicknesses of the three aquifers were identified through interpretation of the well logging data (180 m for Oligocene aquifer, 445 m for the Middle Eocene aquifer, and 145 m for Nubian sandstone aquifer). The present study discusses the groundwater levels, the geological controls and groundwater chemistry of the recorded aquifers. The low salinity values (560-916 mg/l) and water table map as well as the obtained stable isotopes data reveal that the Middle Eocene aquifer is recharged from the Nile River where it has isotopic signature of the modern Nile water with slightly contribution of paleo-water of the Nubian sandstone. The area is affected by sets of faults associated with fractures and joints and facilitates the groundwater recharge. Based on multi GIS data layers, remote sensing data, geologic investigation as well as geophysical data, a future groundwater strategy were presented.

Classification and Mapping of Land Productivity, Capability and Suitability for Production Crops in West El-Minia Governorate, Egypt

“…El-Minya area is represented by Tertiary and Quaternary alluvial deposits consist of sand dunes, Nile silt, proto-nil and pre-nil deposits (Klitzsch et al, 1987;El Sayed, 2007 andYousif et al, 2018). According to Abou Heleika and Niesner (2008), West El-Minya area is predominantly composed of Quaternary sediments (Nile Silt, Prenile deposites, Protonile deposites, Sanddunes, Wadi deposites, Playa deposites, Fanglomerate and Gravel), Miocene (Moghra Fm.…”

“…Growing population, agricultural expansion, and urbanization has placed a heavy pressure on water resources (Hanh et al, 2017), the most important problem in Egypt is the ratio between land and human resources (Abdel-Hamid et al, 2010). West El-Minya area is considered one of the promising areas for agricultural sustainability in Egypt (Yousif et al, 2018).…”

Groundwater Potentials of Eocene Limestone Aquifer in West-West El-Minya Area, Egypt

“…The annual rainfall value is about 19.6 mm/year (Salem, 2015). So, the input of rainfall to groundwater recharge is limited (Yousif et al, 2018). Evaporation in "El-Minya governorate" ranges from 14.85 mm/month in June to 3.54 mm/month in December, with the average value of 8.92 mm/month and total amount of about 107.04 mm/year.…”

Specifying of aquifer characteristics using forward and inverse modeling of DC-resistivity and TEM methods

“…The local litho-stratigraphic sequence is ranged from Lower Eocene to Recent, as shown on Figure 5 (reprinted and modified after Yousif et al., 2018 ) and represented by several formations. Bahariya Formation is exposed at the Bahariya Oasis and consists of friable variegated sands, sandstones and claystone, with hard brown ferruginous bands ( Said, 1962 ).…”
