The NexGen project is developing successor software packages to the existing family of HEC computer programs. Development is occurring via teams comprised of technical specialists, computer scientists, and consultants. Modern software engineering methods are being used and object-oriented program architecture is being employed. Version 1.0 of the River Analysis System (HEC-RAS) was released in August 1995. The Beta version of the Hydrologic Modeling System (HEC-HMS) and Flood Damage Analysis program (HEC-FDA) are targeted for release in winter/spring 1996. This paper describes the evolution and status of the HEC family of programs, the objectives and management approach for NexGen, and findings and status of the project to date.
