Dam engineering involves the design, construction, and maintenance of structures that hold back water, creating reservoirs for various purposes. These structures can help with flood control, irrigation, and hydroelectric power generation. Engineers must consider factors like water pressure, materials, and environmental impact when planning a dam. The process includes site selection, where engineers assess the landscape and water flow, followed by designing the dam's structure to ensure safety and efficiency. Regular inspections and maintenance are crucial to prevent failures, which can lead to significant environmental and human risks.
