“…Calcium carbonate content ranges between 20.45 to 81.82 %. Also, Bahnasawy (2018) showed that soil texture of the studied profiles ranges between loamy sand and light clay except the subsurface layer of profile 3 in the soils of Marsa Matruh which is sandy texture. Organic matter (OM) content is quite low being in the range of 0.2 to 1.4 g/100g.…”

ATER resources in the Northwestern Coastal Zone (NWCZ) of Egypt are very limited in terms of quantity, as they are produced mainly from rainwater in the winter season. Water scarcity is the main impediment to development activities in the region. Prepare Rain Water Harvesting (RWH) is one of the most effective solutions to beat this problem. The study area (El-Hraka basin) is located in northwest coast of Egypt near Matrouh city. The aim of this study is to assess the potentiality of El Harak basin for water resources management and agricultural development activities. The study aimed also to predict annual peak flow and runoff water volume, as well as the 20, 10, 5, 3, and 2 year return periods. Results referred that El-Hraka basin characterized by an area of 178.31km 2 , basin length of 33.70 km, perimeter of 132.8 km, and gentle slope of 0.012 m/m. There are four types of land use/land cover in the study basin named: agriculture land, bare land, rocky areas and urban representing 3.45, 92.98, 3.41 and 0.16% of El Hraka basin, respectively. There are two hydrologic soil group of the study basin A and C depending on the soil texture. The Curve Number (CN) depending on the land use / land cover and the hydrologic soil groups. Its average values are 73.67 for El-Hraka basin. The annual runoff water volumes are 10583.29 m 3 that recharge the groundwater reservoir. However, the annual infiltration volumes are 8195.01 m 3. The peak flow of the 20, 10, 5, 3 and 2 year return periods flash flood is 29.24, 17.98, 9.50, 3.78 and 0.75 m 3 /s respectively. The runoff volume of the 20, 10, 5, 3 and 2 year return-periods is 2.78 million, 1.71 million, 906,578.6, 359,883and 69,989.4 m 3 respectively for the study basin.

“…Results in Table 3 showed that the clay minerals in studied soils were mainly quartz and kaolinite (from level common to dominant) with variable quantities of other minerals. Bahnasawy(2018)found the dominance of quartz in the northwest coast soils. Although smectite mineral was present in moderate amounts of soil profiles No.…”

LAY mineralogy studies were essential for understanding the weathering environments and source regions of fluvial sediments affected by construction of the High Dam. This study conducted in Aswan Governorate, Egypt, to knowing the minerals formed the clay fraction separated from some horizons of soil profiles. To achieve this purpose, were taken eight soil profiles from the western side of Nasser Lake to evaluate some soil properties and study clay mineralogy. The clay fraction was separated from the layers have a high content of clay and prepared for X-ray diffractometry which used to determination, to define of the different clay and accessory minerals. Our results showed that, the soil pH ranged from neutral (7.36) to highly alkaline (8.9), and it was classified as non-saline to highly saline and slightly to moderately calcareous. So, the values of soil EC ranged from 0.17 to 5.8 dSm -1 and CaCO 3 ranged from 0.04 to 7.39%, respectively. Moreover, the cation exchange capacity (CEC) was low to very high, ranging from 6.1 to 44.28 CmoL c kg -1 , with a predominantly sandy texture. Also, results revealed that, dominated contents of kaolinite minerals indicated followed by smectite, micasmectite, vermiculite, Sepiolite and plagioclase. The identified accessory minerals were dominant quartz followed by aragonite, calcite and hematite. In general, weathering was not severe because accessory minerals were not formed in large quantities, and perhaps these obtained results are due to the type of parent material predominated, whether present in the study area or transported across of Nile River to the place of sedimentation, and the weather conditions prevailing in the study area helped in that.

“…Distributions of the resistant minerals indicate that the soils are generally of multi-origin and/or multi-depositional regime and are thus young. X-ray diffraction of clay minerals showed the predominance of kaolinite, followed by montmorillonite (Bahnasawy, 2018). Ismail, et al (2012) studied the mineralogy of the sand fraction in south east of El-Qattara Depression (near the studied area).…”
