Water scarcity and environmental concerns have become pressing issues in the modern world, necessitating innovative approaches to water management. Global issues including water scarcity and environmental concerns now require creative and sustainable approaches to managing water resources. This chapter will examine how the internet of things (IoT) and cutting-edge technologies like machine learning (ML) are revolutionizing the way that water management is done. In this chapter, the effective uses of machine learning in water resource analysis will be examined. Forecasting water demand requires the use of ML algorithms, which help water managers predict consumption trends with accuracy. Predictive analytics can also be used to evaluate the distribution and availability of water, providing information on how to allocate and optimize water resources. The chapter concluded with revolutionary potential of machine learning and the internet of things in modernizing water management practices globally.
