GLOBAL GEOPHYSICAL HAZARDS: INTEGRATING MECHANICAL EROSION MODELING WITH REGIONAL MUDFLOW AND COASTAL GROUNDWATER VULNERABILITY ASSESSMENTS

Abstract

This article analyzes the critical intersection of mechanical erosion modeling in multi-phase mass flows and the subsurface impacts of sea-level rise (SLR) on coastal groundwater dynamics. By employing the Unified Mechanical Erosion Model (UMEM), the study evaluates geophysical hazards in volatile mountainous corridors—specifically utilizing Uzbekistan's Fergana Valley as a primary case study—while concurrently addressing the "hidden" convergence of impacts in global coastal megalopolises. The research details how subsurface hydrological shifts compromise urban infrastructure, mobilize contaminants, and threaten public health. Ultimately, this unified framework provides a corrective roadmap for international policymakers, advocating for a transition from reactive, single-phase catastrophe management to proactive, data-driven adaptive strategies.
