Hydrological modelling is a term used to describe the process of using computer algorithms to simulate the behavior of water in natural systems. Other synonyms for this process include hydrological simulation, water modelling, watershed modelling, or water resource management. These terms are often used interchangeably depending on the context in which they are used and the specific aspects of water management being described. Regardless of the terminology used, the ultimate goal of hydrological modelling is to help predict and manage water resources, both to safeguard natural ecosystems and to support human activities such as agriculture, industry, and urban development.
