“…Several shape files are generated using DEM ASTER 30 m, and the main sub-basins are extracted using Sudr basin stream generation. Watersheds and stream generations in sub-basin 1 are delineated using the Alos Palsar digital elevation model (DEM) with a resolution of 12.5 m [50,51].…”

El-Gendi Fortress is a unique geo-archaeological site in Sinai, Egypt. It reflects the progress of the Islamic military architecture during Saladin’s reign (Salah ad-din al Ayyubi), the founder of the Ayyubid dynasty (1174-1260AD). The fortress's location met two major geo-criteria. One is geographical; it is located on a mound 655 m above sea level (a.s.l) and 152 m above El-Tih El-plateau; this elevation contributes to the exploration of the surrounding areas and provides the fortress with a strong defensive position against the Crusaders' invasions of Egypt (1163–1169 AD). The second is Hydro-geological; it provides exceptional access to both meteoric surface (via barrages) and groundwater (through Sudr spring). The latter is from deep aquifers of the Nubian sandstones (Malha Formation) across the fractured carbonates (Raha and Sudr Formations of Cenomanian to Maastrichtian age). Such water was accumulated since the Pleistocene pluvial age until the fortress’ most recent use. The barrages’ location upstream of a sub-basin “a” at Wadi Sudr, in a similar direction to the deep ditch side, confirms that the priority of their design is to protect the region from flash flood risks and to store water on a relatively flat-lying land. The study reveals that the fortress’ geographical location is used to safeguard the Hajj route in central Sinai and to provide facilities for pilgrims’ caravans when they travel from North Africa to Mecca. The study concludes that the fortress should be a part of the Sinai tourism itinerary and promoted globally as a geo-archaeological site for Geo-tourism. In addition, the government should implement a strategy for conserving, rehabilitating, and managing the heritage sites, to improve facilities and increase public awareness of these sites to maximize the outcomes.

“…The stream frequency is the total number of stream segments of all order per unit area. Stream frequency primarily depends on the lithology of the basin and reflects the drainage texture of the drainage network (Bismark Mensah-Brako, 2018) [16]. Drainage frequency mainly depends on the lithology of the basin, high drainage frequency will lead to a more surface runoff, while low drainage frequency leads to more percolation and therefore more groundwater potential (Resmi MR et al, 2019).…”

The present study relates to the morphometric analysis of Kanthatmakur vagu watershed using GIS. The GIS platform facilitates the analysis of various morphometric parameters. This watershed has higher order of 5th order. The present study has area of about 440.4 Km2 with total length of basin is 45.5 Km. Total number of streams in the basin is 635, ranging from 10 to 319. The basin area exhibits dendritic drainage pattern with bifurcation ratio ranges from 0.1 to 9.2, with mean bifurcation ration of 3.4. Length of stream of all orders are 481.8 km. Length of overland slow is 0.55 km and perimeter of the basin found to be 119.7 km. Areal aspects such as drainage density is calculated as 1.1, drainage frequency is 1.4 and drainage texture calculated as 5.3. Infiltration number of the watershed is 0.8. The watershed has 0.3 form factor ratio, 0.5 elongation ration and 0.4 circularity ratio. Relief of the watershed is 261m and ratio of relief is 6.3. The characteristics of morphological analysis of the Kanthatmakur vagu watershed has peak flow, is an elongated and less probable to flooding as well as moderate to slightly steep slope. In the watershed infiltration is high and run off will be low.

Quantitative morphometric analysis was carried out for Megech-Dirma, sub-basin of the Blue Nile, by estimating (1) linear, (2) aerial, and (3) relief aspects. An endeavor has been made to measure the Megech-Dirma watershed’s morphometric characteristics to implement conservation methods for soil and water properly. ASTER DEM has been used as input data for extracting morphometric parameters. Strahler’s classification scheme was used to classify the extracted drainage network in ArcGIS extension ArcMap 10.4. The watershed covers a total surface area of 1309.56 km2. The shape of the watersheds as calculated from elongation, circularity, and form factors reveals the elongated shape and the watersheds parade dendritic pattern. The sub-watersheds include third-order for Megech and sixth-order streams. Lower stream orders, in particular first-order streams, dominate the sub-watersheds. The length of overland flow has a higher value (1.06) for Megech indicates low relief, whereas the values of length of overland flow, which are relatively low (0.20) for Dirma, indicate high relief. The drainage density of the study watershed was morphometrically analyzed and obtained 0.47 km/km2 for the Megech sub-basin, which indicates the basin is highly permeable and result in better underground water storage capacity and 2.46 for the Dirma sub-basin indicating very coarse and coarse channel, respectively. The ruggedness number for Megech and Dirma sub-basins was 0.56 and 0.07, respectively, indicating moderate and long, rugged topography, which could be susceptible to flash flood and soil erosion. The dissection index values for Megech 0.40 and 0.36 for Dirma show river sub-basins are moderately dissected. The ruggedness number is 0.56 for Megech implies moderate soil erosion probability, whereas the high infiltration number (14.29) for Dirma river shows the high runoff potential in the sub-basin. The findings of this study include drainage morphometry data that can be used to better understand watershed characteristics and serve as a framework for better planning, management, and decision-making to ensure the long-term use of watershed resources of water and soil.
