Download or read book Use of a Two dimensional Flow Model to Quantify Aquatic Habitat written by D. Michael Gee and published by . This book was released on 1985 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper describes the impacts of potential hydropower retrofits on downstream flow distributions at Lock and Dam No. 8 on the upper Mississippi River. The model used solves the complete Reynolds equations for two-dimensional free-surface flow in the horizontal plane using a finite element solution scheme. RMA-2 has been in continuing use and development at the Hydrologic Engineering Center and elsewhere for the past decade. Although designed primarily for the simulation of hydraulic conditions, RMA-2 may be used in conjunction with related numerical models to simulate sediment transport and water quality. In this study, velocity distributions were evaluated with regard to environmental, navigational and small-boat safety considerations. Aquatic habitat was defined by depth, substrate type and current velocity. Habitat types were quantified by measuring the areas between calculated contours of velocity magnitude (isotachs) for existing and project conditions. The capability for computing and displaying isotachs for the depth-average velocity, velocity one foot from the bottom and near the water surface was developed for this study. The product of this study effort is an application of the RMA-2 model that allows prediction of structural aquatic habitat in hydraulicaly complex locations. Elements of the instream flow group methodology could be incorporated to provide detailed predictions of impacts to habitat quality. Calibration of the numerical model to field measurements of velocity magnitude and direction is also described.

Book excerpt: 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.

MacArthur and published by . This book was released on 1982 with total page 283 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objectives of the seminar were: (1) to bring together developers, users, and potential users of two-dimensional mathematical models to develop a continuing dialogue concerning applications experience, problem identification, research goals, model evaluation, operational problems and model limitations; (2) to make researchers working in the areas of riverine and flood plain simulation aware of recent advances in coastal and estuarine modeling; and, (3) to examine mechanisms for transferring technology to field offices and field needs to research programs. The seminar emphasized two-dimensional homogeneous flows in the horizontal plane such as occur in rivers and well-mixed bays and estuaries. Papers focused on model application, features, performance and utility rather than recent research advances.

Book excerpt: This paper describes the computational aspects and computer usage history of numerical simulations of horizontal, free surface, steady or unsteady two-dimensional flow fields. The focus is on a particular numerical model (RMA-2) that has been in use and development at the Hydrologic Engineering Center (HEC) and elsewhere for the past decade. RMA-2 solves the complete Reynold's equations for turbulent flow in two dimensions using the finite element method. Terms describing bottom friction, surface wind, and Coriolis forces are included. Details of the governing equations and solution technique are thoroughly documented elsewhere. RMA-2 may be used as a driver for sediment transport and water quality simulations as well as for computing hydrodynamic information only.

Available in PDF, EPUB and Kindle. Book excerpt: A numerical flow model, HIVEL2D, has been developed as a tool to evaluate high-velocity channels. HIVEL2D is a depth-averaged, two-dimensional flow model designed specifically for flow fields that contain supercritical and subcritical regimes as well as the transitions between the regimes. The model is a finite element description of the two-dimensional shallow-water equations in conservative form. Provided in this report are a description of the numerical flow model and illustrative examples of typical high-velocity flow fields that the model is capable of simulating. Model verification is obtained by comparison of simulation results with data obtained from flume studies. Model assumptions and limitations are also discussed.
