Introduction
Water is a finite and invaluable resource critical to human survival, agriculture, industry, and ecological balance. As global populations increase and climate change disrupts natural water cycles, the demand for sustainable water management has never been more urgent. Enter Artificial Intelligence (AI) — a powerful enabler of smart, data-driven, and efficient water resource management systems.
AI-powered Water Management integrates machine learning, data analytics, remote sensing, and Internet of Things (IoT) to address challenges such as water scarcity, leakage detection, flood prediction, irrigation control, and wastewater treatment. This article explores how AI is revolutionizing water management through intelligent systems, applications, benefits, challenges, and its future potential.
The Need for Smart Water Management
Growing Water Demand
