Integrated Water Resources Management Under Climate Change: Advances in Hydrology, Hydraulic Engineering, and Emerging Technologies

Abstract

Integrated Water Resources Management (IWRM) has emerged as a comprehensive and adaptive framework for addressing the growing challenges of water scarcity, increasing demand, and the intensifying impacts of climate change. Climate variability and long-term climate change have significantly altered global and regional hydrological cycles, resulting in shifts in precipitation patterns, increased frequency and intensity of extreme hydrological events, and disruptions in water availability, timing, and quality. These changes have profound implications for agricultural productivity, ecosystem sustainability, urban water supply, and socio-economic development.

This review critically examines recent advances in hydrology, hydraulic engineering, and emerging geospatial and computational technologies that support the implementation of IWRM under changing climatic conditions. Significant progress has been made in hydrological modeling techniques, including physically based, conceptual, and data-driven approaches, which enhance the understanding and prediction of complex water system dynamics. In parallel, innovations in climate-resilient hydraulic infrastructure—such as adaptive dam operation systems, flood control structures, and sustainable irrigation networks—are contributing to improved water management efficiency and resilience.

Furthermore, the integration of Geographic Information Systems (GIS), Remote Sensing (RS), and Artificial Intelligence (AI) has transformed decision-making processes in water resource management. These technologies enable real-time monitoring, spatial analysis, predictive modeling, and scenario-based planning, thereby enhancing the accuracy and effectiveness of water governance strategies. The convergence of these tools within an IWRM framework facilitates data-driven, adaptive, and participatory approaches to water management.
