dc.description.abstractThe Hydrologic Engineering Center (HEC) is developing next generation software for one-dimensional river hydraulics. The HEC-RAS River Analysis System (HEC, 1994) is intended to be the successor to the current steady-flow HEC-2 Water Surface Profiles Program (HEC, 1990a) as well as provide unsteady flow, sediment transport, and hydraulic design capabilities. A common data representation of a river network is used by all modeling methods, thus allowing the user to more easily migrate from steady-flow to other one-dimensional flow calculations. The concept also provides a consistent usage of data among the modeling methods. The HEC-RAS program provides a steady-flow model with several significant advances over HEC-2. An overview of the program package and some of the improved hydraulic features are presented. The Version 1.0 steady-flow model is targeted to be released early in 1995, and unsteady-flow capability is planned for the following year.en_US
