Identifying areas susceptible to flash flood hazards is essential mitigating their negative impacts, particularly in arid regions. For example, southeastern Sinai, the Egyptian government seeks develop its coastal along Gulf of Aqaba maximize national economy while preserving sustainable development standards. The current study aims map and predict prone utilizing a spatial analytic hierarchy process (AHP) that integrates GIS capabilities, remote sensing datasets, NASA Giovanni web tool application, principal component analysis (PCA). Nineteen triggering parameters were initially considered for developing susceptibility model by conducting detailed literature review using our experiences food studies. Next, PCA algorithm was utilized reduce subjective nature researchers’ judgments selecting factors. By reducing dimensionality data, we eliminated ten explanatory variables, only nine relatively less correlated factors retained, which prevented creation an ill-structured model. Finally, AHP method determine relative weights based on significance floods. resulting as follows: rainfall (RF = 0.310), slope (S 0.221), drainage density (DD 0.158), geology (G 0.107), height above nearest network (HAND 0.074), landforms (LF 0.051), Melton ruggedness number (MRN 0.035), plan curvature (PnC 0.022), stream power index (SPI 0.022). research proved AHP, among most dependable methods multi-criteria decision-making (MCDM), can effectively classify degree risk ungauged areas. found 59.2% area assessed at very low flood, 21% high risk, 19.8% moderate risk. Using under receiver operating characteristic curve (AUC ROC) statistical evaluation metric, GIS-based developed demonstrated excellent predictive accuracy, achieving score 91.6%.

Effective management of groundwater resources is vital in arid and semi-arid regions like the Yalamlam Basin. Identifying appropriate places for artificial recharge key to addressing water shortages guaranteeing long-term viability aquifers. By combining Analytical Hierarchy Process (AHP) approach with GIS technology, this research offers a thorough framework evaluating potential recharge. Data collection study includes lineament density, slope, drainage rainfall, Land Use/Land Cover (LU/LC), soil, elevation, TWI, among other crucial variables. In study, LULC, elevation TWI are most sensitive characteristics relative weights 30, 23, 16, 11, 8, 5, 4 3%, respectively. According study’s findings, there many zones region varying capacities recharging. Based on locations that may be used recharge, findings were categorized into five groups: very high (12.7%), (23.3%), moderate (29.6%), poor (24.4%), (10%). The validation protection was conducted by using eight wells basin. As part process, Total Dissolved Solids (TDS) boreholes (GWPZs) compared. A strong positive correlation found between them (0.61). results can provide valuable information creation policies focus specific actions boost These considerably enhance effectiveness efforts aimed at implementing customized methods encourage suggest substantial prospects planning tackle issue availability region.

ABSTRACT The discourse on climate change has brought to the fore pressing need for improved flood management strategies. Recent trends indicate a surge in flooding incidents residential areas, which can potentially disrupt socio‐economic activities and result loss of lives. This study conducts Systematic Literature Review (SLR) comprehensively assess compare various mitigation strategies employed zoning practices globally. Residential New Zealand means designated area land specifically set aside housing development, with rules regulations governing density type dwellings that be built there maintain suitable living environment residents. Research articles published between 2001 2024 focused reduction were collected, synthesised, analysed. A predefined review protocol guided this approach, involving searches widely used electronic databases. Ninety‐three ultimately included review. findings highlight several key including impact susceptibility, effectiveness rainwater harvesting systems green infrastructure management, importance sustainable urban development ecological preservation. Proposed strategies, such as neighbourhood site planning, regional stormwater roofs, permeable pavements, regulatory measures, offer valuable pathways safeguarding water resources planning efforts. advances knowledge environmental sustainability, practices. It also provides an overview current approaches mitigating identifies research gaps future studies.

Abstract This study investigates the source, environmental impact, and health risks of potentially toxic metal(loid)s (PTMs) in agricultural soil from Al Lith area along Red Sea coast Saudi Arabia. Soil samples were collected 25 farms analyzed using inductively coupled plasma–atomic emission spectrometry. Various indices used to assess contamination samples. Most belonged Entisols, specifically Torripsamment, Torrifluvent, Udipsamment subtypes. It was found that average concentrations PTMs follow order Zn (43.69) > Cu (21.69) Ni (18.92) Co (10.12) Pb (2.62) As (1.67). The values indicated minor enrichment, low contamination, risk for all PTMs, with enrichment observed some individual higher levels reported areas surrounding Wadi mouth. Multivariate statistics suggested primary source geogenic, derived weathering basement rocks Arabian Shield. mean hazard index (HI) humans (adults children) followed Zn. collective HI stayed below 1.0, indicating a non-carcinogenic risk. Additionally, lifetime cancer lower than 1 × 10 −4 , an acceptable or tolerable level carcinogenic suggesting negligible hazards.
