HEC-RAS (Hydrologic Engineering Center - River Analysis System)

HEC-RAS (Hydrologic Engineering Center - River Analysis System) is a software tool used by engineers and hydrologists to simulate and analyze river behavior. It helps model how water flows in rivers and streams, taking into account factors like terrain, rainfall, and structures such as dams or bridges. By doing so, it allows professionals to predict flood risks, design river modifications, and plan for flood management effectively and safely. Essentially, HEC-RAS provides a detailed virtual view of river systems to support informed decision-making and infrastructure planning.
