Book Description
Since the Hydrologic Engineering Center (HEC) was established in 1964, it has provided training in hydrologic engineering for the Corps of Engineers. The Center has also been responsible for computerizing hydrologic methods and making those programs available to the Corps as well as the general public. These computerized procedures and the required information for project investigations have grown to the point that the program user requires an understanding of a multitude of technical fields. The development of comprehensive computer programs provides an opportunity to bring together previously fragmented technical studies into one integrated study. Several examples of the coordinated program packages and their impact on the evolving training program of the HEC are presented to illustrate the developing technology and its impact on the training and education needs of engineers in the Corps.

Book Description
A two-dimensional horizontal finite element numerical model (RMA-2) was applied to a 15 mile (24 km) river channel-floodplain reach in West Germany. Previous applications of such models have been restricted to much smaller scales. The results indicate that finite element schemes may successfully estimate river stage in large scale floodplain applications. Computed stage hydrographs compared well with observed data using loss coefficients within expected ranges. Two-dimensional flow models have been applied to certain classes of river channel problems. Applications have included detailed analyses of flow patterns near structures such as bridges and floodplains. In all these problems the scale of interest has been small, e.g. reaches of river a few river widths long. Many estuary studies have been done that were of large scale; some of these utilized a hybrid (numerical plus physical) modeling technique. In a review of the application of finite element methods to river channels, Samuels reported that the river channel was resolved separately from the floodplain in only two studies. Missing in previous work is attention to large scale floodplain modeling. The work reported in this paper focuses on the feasibility and accuracy of applying a two-dimensional flow model to a large floodplain. Traditional floodplain studies have used semi-empirical flow routing with steady, one-dimensional computation of water surface elevations to define inundated areas. Keywords: Army Corps of Engines.

Book Description
The Corps' Hydrologic Engineering Center (HEC) has developed a generalized simulation model capable of analyzing complex river-reservoir systems. The development of the model, 'HEC-5, Simulation of Flood Control and Conservation Systems' (Eichert, 1974, 1975) has been paced by the changing mission of the Corps as well as the evolution of computer systems. HEC-5 development and management, including code development, testing, documentation, training and field application experience, is discussed. (fr).

Book Description
This paper summarizes the procedures used for computing the basinwide annual yields and single event sediment production for ephemeral channels located on an incised alluvial fan in Central California. Unique geomorphic characteristics of the basin and alluvial fan are discussed in light of data and analytical methods necessary to compute sediment delivery and yield at a proposed dam site.

Book Description
The methodology and difficulties in converting a large, general purpose, mainframe, batch oriented computer program (for reservoir simulation) to work effectively in the PC environment are described in this paper. A brief overview of the present capabilities of the general purpose reservoir simulation program (HEC-5), that works on mainframe and MS DOS compatible computers, is also presented. Keywords: Simulation, Personal computer, Reservior system, Flood control, Hydropower, Water supply, Computer programs, Multi-purpose, Multi-reservoir, FORTRAN. (jes).
