A dam is a large, artificial barrier constructed across a river or stream to obstruct the natural flow of water, thereby creating an impounded body of water known as a reservoir. These structures are significant examples of hydraulic engineering, designed to withstand immense hydrostatic pressure. The function of a dam is multifaceted, allowing for the controlled management of water resources. Key applications include the generation of hydroelectric power, providing reliable electrical energy, and the regulation of water flow for downstream purposes such as maintaining navigable rivers, supporting agricultural irrigation, and mitigating flood risks. Different types of construction methods are employed depending on the geological structure of the site and the desired operational capacity.
