Flash floods are highly destructive natural disasters, particularly in arid and semi-arid regions like Egypt, where data scarcity poses significant challenges for analysis. This study focuses on the Wadi Al-Barud basin Egypt’s Central Eastern Desert (CED), a severe flash flood occurred 26–27 October 2016. event, characterized by moderate rainfall (16.4 mm/day) total volume of 8.85 × 106 m3, caused minor infrastructure damage, with 78.4% occurring within 6 h. A portion floodwaters was stored dam reservoirs, reducing downstream impacts. Multi-source data, including Landsat 8 OLI imagery, ALOS-PALSAR radar Global Precipitation Measurements—Integrated Multi-satellite Retrievals Final Run (GPM-FR) precipitation geologic maps, field measurements, Triangulated Irregular Networks (TINs), were integrated to analyze event. The Soil Conservation Service Curve Number (SCS-CN) method several hydrologic models, Hydrologic Modelling System (HEC-HMS), Water Assessment Tool (SWAT), European Hydrological Model (MIKE-SHE), applied evaluate forecasting, watershed management, runoff estimation, results cross-validated using TIN-derived DEMs, imagery. SCS-CN proved effective, percentage differences 5.4% 11.7% reservoirs 1 3, respectively. High-resolution GPM-FR ALOS-derived soil texture mapping valuable analysis data-scarce regions. concluded that existing protection plan is sufficient 25- 50-year return periods but inadequate 100-year events, especially under climate change. Recommendations include constructing additional (0.25 m3 m3) along Kahlah Delta, reinforcing Safaga–Qena highway, building protective barriers divert floodwaters. methodology applicable similar events globally, advancements geomatics datasets will enhance future prediction management.

Coastal hazards refer to various natural processes and events occurring at coastlines are driven by a combination of geological, meteorological, oceanographic factors, posing risks human activities, infrastructure, the environment. Efforts mitigate consequences these essential minimize potential ensure sustainability nearshore communities. Such efforts developing early warning systems, constructing protective structures, proper land-use planning, sustainable coastal management practices. In last decade, become more severe due climate change which directly contribute sea level rise, storm intensification, flooding. Therefore, investigating in specific region is utmost importance understand degree hazard prepare effective mitigation strategies. This study specifically delves into examination along mainland Kedah areas Langkawi Island. It involves comprehensive analysis historical incidents prognosis future scenarios. The focuses on three primary hazards: tsunamis, floods, rising levels. Particularly, it scrutinizes significant past occurrences, notably devastating tsunami 2004.

Abstract Water scarcity is a pressing global challenge, and arid regions like Saudi Arabia face the urgent need for effective water stress management. The current study proposes an innovative method to tackle this issue by utilizing hybrid time series analysis model, comprising of Autoregressive Integrated Moving Average (ARIMA) Generalized Least Squares (GLS) techniques estimate groundwater depletion trends in Arabia. research employs historical data, climatic variables, socioeconomic indicators formulate comprehensive insight factors influencing depletion. ARIMA component model captures temporal dynamics levels, while GLS considers spatial cross-correlation dependencies among observation points, enhancing accuracy estimates. also demonstrates significance variability exacerbating region. Furthermore, ARIMA-GLS offers robust tool forecasting future trends, aiding proactive decision-making mitigating stress. numerical results different wells proved be essential assessing Mean Absolute Percent Error (MAPE). For instance, MAPE values were found as (i) ARIMA-CLS (MAPE = 0.1507), (ii) 0.429834), (iii) 0.109115) 4-H-84-N, 4-H-86-U, 4-S-316-U, respectively with expectation (iv) ARI 6.0285) DA-45-U well.

Saudi Arabia is threatened by recurrent flash floods caused extreme precipitation events. To mitigate the risks associated with these natural disasters, we implemented an advanced nationwide flood forecast system, boosting disaster preparedness and response. A noteworthy feature of this system its national-scale operational approach, providing comprehensive coverage across entire country. Using cutting-edge technology, setup incorporates a state-of-the-art, three-component that couples atmospheric model hydrological hydrodynamic models to enable prediction patterns their potential impacts on local communities. This paper showcases system’s effectiveness during event struck Jeddah 24 November 2022. The event, recorded as heaviest rainfall in region’s history, led widespread floods, highlighting critical need for accurate timely forecasting. proved be effective tool, enabling authorities issue warnings well before flooding, allowing residents take precautionary measures, emergency responders mobilize resources effectively.
