Fifteen hydrogeologically significant conditioning factors were prepared from multi-source geospatial data (ALOS PALSAR DEM, Sentinel-2, Geological Survey of India, Central Ground Water Board), and 66 verified groundwater well observations were partitioned into training (60.6%, <i>n</i> = 40) and testing (39.4%, <i>n</i> = 26) subsets. The AHP model employed a pairwise comparison matrix with a Consistency Ratio of 0.08, while FR assigned bivariate weights across all factor sub-classes. The LR model used a Principal Component Analysis-based Mahalanobis distance framework, retaining components explaining ≥ 95% of the variance, and the RF model employed 500 trees with mtry = 4. Model performance was evaluated through Receiver Operating Characteristic (ROC) curves, Area Under the Curve (AUC), Seed Cell Area Index (SCAI), and Pearson correlation analysis. The RF model achieved the highest predictive accuracy (AUC = 0.75), followed by LR (0.75), FR (0.72), and AHP (0.66), confirming that data-driven approaches outperform expert-based MCDA in capturing complex hydrogeological relationships. Variable importance analysis identified Geomorphology (4.21), LULC (2.19), and NDVI (2.04) as the dominant predictors. SCAI represents the ‘Moderate’ GPZ class as the most spatially coherent (SCAIₚₕₚ = 0.61; SCAIₕ_r = 0.51). Spatial outputs revealed that 36–40% of the 6,259 km² district falls within the ‘High’ to ‘Very High’ potential range, concentrated in the northeastern and southeastern blocks, which are underlain by metamorphosed volcanic rocks, sandstone outcrops, and pediment zones.

This review examines recent developments between 2019 and 2025, with particular attention to the expanding use of Geographic Information Systems (GIS), remote sensing, and artificial intelligence (AI) in modelling climate-related hazards such as floods, droughts, wildfires, and coastal processes. A structured screening of peer-reviewed literature retrieved from Scopus and Web of Science, supplemented by searches in Google Scholar, resulted in the retention of 121 peer-reviewed journal articles for analysis, covering floods, droughts, wildfires, and coastal hazards. The review identifies a pronounced methodological transition from conventional statistical and GIS-overlay approaches toward machine learning, deep learning, and hybrid modelling frameworks better suited to capturing nonlinear and dynamic hazard interactions. While these approaches often enhance predictive performance, several challenges remain, including data scarcity, spatial autocorrelation bias, validation constraints, and limited transferability across diverse climatic contexts. Moreover, although AI-based models frequently report higher predictive accuracy, their interpretability and integration into operational planning and risk management systems remain uneven, particularly in data-constrained environments. Using Morocco as an illustrative case of climatic heterogeneity and uneven monitoring infrastructure, this review underscores the importance of developing climate-aware, transparent, and transferable modelling strategies that integrate remote sensing time series, physical process understanding, and rigorous validation practices. Strengthening these dimensions is essential to ensure that methodological advancements translate into effective risk reduction and adaptive planning.</p></div>","PeriodicalId":476,"journal":{"name":"Arabian Journal of Geosciences","volume":"19 9","pages":""},"PeriodicalIF":1.827,"publicationDate":"2026-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148838001","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
