The present study is an attempt to evaluate the watershed characterization and potentiality of Wadi El-Arish, Sinai, Egypt using Remote Sensing (RS) and Geographic Information System (GIS) techniques. Thirty morphometric parameters (e.g. stream numbers, orders, lengths, frequency as well as bifurcation ratio, drainage density and relief) were measured depending on SRTM data of digital elevation model (DEM) with 30m resolution that enhanced by topographic maps (1:50,000). Ten compound parameter values were calculated and prioritization rating for erosion risk assessment was carried out. Based on the values of the effective morphometric parameters, flash flood hazards were identified and evaluated. The land use map was constructed from the geomorphological units of Wadi El-Arish basin as well as the field observations. The drainage area of Wadi El-Arish watershed is 22260.3 km 2 . It is subdivided into twelve sub-basins of different areas. The morphometric analysis indicates that the watershed is of eight stream order with dendritic type of drainage pattern and homogeneous nature. The relief ratio, slope, ruggedness number and visual interpretation of the DEM indicate variable slope and topography with late mature stage of geomorphic development. On the other hand, the drainage density, texture, circulatory and elongation ratios prove that the majority of the sub-basins are almost elongated and have coarse and intermediate drainage texture which indicate medium to high infiltration capacity. Accordingly, these sub-basins most probably have good groundwater prospect where the most rainfall infiltrate to recharge the aquifer via permeable soils and/or fractured and weathered rocks. Concerning the soil erosion condition, the sub-basins with the lowest compound parameter value (e.g. W10: Wadi Abu Aliqanah and W12: Wadi Aqabah) have been subjected to maximum soil erosion and need immediate soil conservation measures. Based on the morphometric parameters which have a direct influence on flooding prone area, the flash flood hazard of Wadi El-Arish sub-basins are classified into three groups; namely high, medium and low hazard degree. For mitigation measure (e.g. erection of the runoff water) some dams and dikes at the crossing point between the seventh stream order and eighth stream order are recommended to be constructed. In addition, these measures will support the recharging of the shallow groundwater storage and aquifers. According to the potentiality of the study watershed, the land use map which constructed from the geomorphological units classified the Wadi El-Arish basin into four classes; Open Access Research ArticleIJARSG-An Open Access Journal (ISSN 2320 -0243) International Journal of Advanced Remote Sensing and GIS 1071 namely high, moderate, low and non-suitability classes for agriculture uses. The volume of annual flood for Wadi El-Arish watershed was classified into five classes graded from very high to very low. The groundwater potentiality map indicates that the different geographic locations ar...

“…These technologies have been used to assess the criteria required to define land suitability (El Baroudy, 2016). Remote sensing and GIS were used in many studies in Egypt for land resources mapping and management (Saleh et al, 2013;Mohamed et al, 2014;Saleh and Belal, 2014). RS data coupled with soil survey information can be integrated in the GIS to assess crop suitability for various soil (FAO, 1991, andAbdelRahman et al, 2016).…”

The current study was carried out on the soils of Halaib and Shalatien to estimate their capability and suitability for growing some crops (maize, wheat, alfalfa, potato, sugar beet, citrus, peach and olive). The studied area lies between latitudes 22 ˚ 20 `10`` and 22 ˚ 45 ` 11.5`` N, and longitudes 35 ˚ 55 ` 4.4`` to 36 ˚ 21 ` 4.6`` E. For this purpose, 17 soil profiles were dag and collect of soil samples. The soils were classified as Typic Torrifluvents, Typic Torripsamments, Typic Torriorthents and Lithic AquiSalids. The geomorphologic units of Halaib and Shalatien region are divided into three groups: (1) Bahada Plains (alluvial fans and deltas, alluvial plains, wadis, sand sheets, sand dunes and plains with rock outcrops), (2) Coastal Forms (alkali flats), and (3) Faulted Mountains and Hills (mountains, mountain foot slopes, hills and hill foot slopes). The Automated Land Evaluation System program (ALES program) and Geographic Information System (GIS) were used to evaluate the land suitability in the studied area. Rock land and sand dunes occupied 57.68% of the total area. According to ALES program, the capability of the lands in the study area are grouped into four classes; Class (3) occupied 8.46% of the study area and represented by alluvial fans and deltas mapping units, Class (4) occupied 24.72% of the study area and included alluvial plains, wadis and sand sheets mapping units, Class (5) occupied 7.82% of the study area and included plain with rock outcrops and sand dunes mapping units and Class (6) occupied 1.16% of the study area and represented by only one soil map unit (Alkali flats). According to ALES program, the suitability of the study area classified into four classes: high suitability class (S2) occupying 16.39% of the study area, moderate suitability class (S3) occupying 13.27% of the study area, marginal suitability class (S4) occupying 8.26% of the study area, no suitability class (S5) occupying 3.23% of the study area. The main limitation factors for crop production in the studied area were soil texture, depth and salinity. These limitations are none permanent and can be improved through applied appropriate management practices.

Impacts of Triple Factors on Flash Flood Vulnerability in Egypt: Urban Growth, Extreme Climate, and Mismanagement

et al. 2020

View full text Add to dashboard Cite

Urban growth, extreme climate, and mismanagement are crucial controlling factors that affect flood vulnerability at wadi catchments. Therefore, this study attempts to understand the impacts of these three factors on the flash flood vulnerability in different climatic regions in Egypt. An integrated approach is presented to evaluate the urban growth from 1984 to 2019 by using Google Images and SENTINEL-2 data, and to develop hazard maps by using a rainfall-runoff-inundation model (RRI). Annual rainfall trend analysis was performed to evaluate the temporal variability trend. The hazard maps that were created were classified into three categories (low, medium, and high) and integrated with the urban growth maps to evaluate the impacts on the flood-vulnerable areas. The results show a significant increase in urban growth resulting in an increase of prone areas for flood hazards over time. However, the degree of this hazard is mainly related to growth directions. Mismanagement affects urban growth directions in both planned and unplanned growth, whether by loss of control over unplanned growth or by deficiencies in approved plans. The rainfall analysis showed that there is no explicit relationship to increases or decreases in the flood vulnerable areas. An urban planning approach is recommended for risk reduction management based on a comprehensive study considering such factors.
