Abstract:

Welcome to the Hydrologic Engineering Centers River Analysis System HEC-RAS. This software allows you to perform one-dimensional steady flow, unsteady flow, and sediment transport calculations The current version of HEC-RAS can only perform steady flow calculations. Unsteady flow and sediment transport will be added in future versions. The HEC-RAS modeling system was developed as a part of the Hydrologic Engineering Centers Next Generation NexGen of hydrologic engineering software. The NexGen project encompasses several aspects of hydrologic engineering, including rainfall-runoff analysis river hydraulics reservoir system simulation flood damage analysis and real-time river forecasting for reservoir operations. This chapter discusses the general philosophy of HEC-RAS and gives you a brief overview of the capabilities of the modeling system. Documentation for HEC-RAS is discussed, as well as an overview of this manual.
