Book Description
This thesis documents the development and application of a branch and bound enumeration algorithm for the selection of an optimal flood control plan. An application is presented in which optimal reservoir flood control plans for a three reservoir system are selected. Computer program HEC-5 is used to simulate the reservoir system to determine the modified condition flow-frequency curves, EAD is used to evaluate expected annual damage reductions and the HEC-DSS programs are used to manage the large amounts of data required for the computations. The branch and bound enumeration algorithm provides a systematic evaluation of plans with the HEC programs and expedites identification of the optimal plan by eliminating the need to evaluate all alternative plans. Keywords: Optimization; Planning; Flood control; Plan selection; Systems analysis; Economic analysis. (jhd).

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.
