The Earth’s water resources, totalling 1.386 billion cubic kilometres, predominantly consist of saltwater in oceans. Groundwater plays a pivotal role, with 99% usable freshwater supporting 1.5–3 people as drinking source and 60–70% for irrigation. Climate change, temperature increases altered precipitation patterns, directly impacts groundwater systems, affecting recharge, discharge, temperature. Hydrological models are crucial assessing climate change effects on groundwater, aiding management decisions. Advanced hydrological models, incorporating data assimilation improved process representation, contribute to understanding complex systems. Recent studies employ numerical assess recharge that could help the groundwater. vulnerability assessments vary spatial temporal considerations, well assumptions modelling susceptibility. This review assesses stresses importance accurate sustainable resource management. It highlights challenges related soil aquifer properties, multiple stressors, adaptive capacity, topography contamination processes, gradual sea level rise scenarios, realistic representations region study. With advancements modelling, including integration uncertainty quantification remote sensing data, artificial intelligence assist efforts improve modelling.

The estimation of water requirements constitutes a critical prerequisite for delineating scarcity hotspots and mitigating intersectoral competition, particularly in endorheic basins arid or semi-arid regions where hydrological closure exacerbates resource allocation conflicts. Under conditions scarcity, supplied locally by precipitation shallow groundwater bodies should be taken into account to estimate the net met with conveyed from off-site sources. This concept is embodied distinction blue ET (BET) green (GET).

The Earth's fresh water resources predominantly is groundwater that pumped out due to rapid urbanization and aggravated by climate change. Groundwater modeling a crucial tool for understanding aquifer systems, employing 1D, 2D, 3D numerical models with distinct applications. One-dimensional focus on vertical dynamics, examining properties simulating contaminant transport. Two-dimensional extend regional scales, considering horizontal variations assessing groundwater-surface interactions, making them valuable watershed-scale studies. Three-dimensional provide comprehensive representation of hydrogeological capturing intricate flow patterns aiding site-specific assessments. Comparative analysis reveals model strengths limitations, emphasizing the importance calibration reliable results. Case studies showcase practical applications, such as 1D in flooding 2D debris flows. proves essential complex river-aquifer exchange fluxes. Future directions call global platform address data variability technical challenges. Despite substantial investments required, anticipated returns scientific advancements, societal benefits, economic gains are expected outweigh initial costs. This review aims highlighting significance advancing all three-dimension sustainable resource management environmental protection.
