Book excerpt: Consistent and expedient evaluations of nonstructural flood loss reduction measures for existing and alternatives future land use patterns can be performed using spatial analysis concepts. The techniques developed center about the processing of spatial geographic data into a grid cell data bank and the subsequent accessing and manipulation of pertinent data variables by a computer program. The results are an automatically constructed elevation-damage function at damage reach index locations for selected land use patterns. The modification of the damage function resulting from specific nonstructural alternatives may be performed by inputting into the computer program a target protection level or a specified stage of protection for selected land use categories. These functions may be analyzed conventionally by damage frequency integration methods or used as input into more complex system models. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The goals of nonstructural flood-control planning are formulation, evaluation, selection, and implementation of a practicable management plan that provides optimal protection from the adverse effects of flooding. Many alternative flood-control measures can be dismissed by the water resources planner on the basis of judgement, but a substantial number will require detailed analysis before a suitable plan can be selected. This analysis is an iterative process, requiring input from the planar at each step. Software developed at the Hydrologic Engineering Center (HEC) allows efficient data storage in a structure-oriented data bank and provides for selective retrieval and manipulation of the data from an interactive terminal. Thus the planner is able to propose nonstructural measures and to evaluate rapidly the economic and technical feasibility of those measures in a iterative scheme that allows the required input from the planner. An application of the interactive plan evaluation software is presented. Steps in creating the data bank are defined, and use of the software for subsequent accessing and manipulating the data for plan evaluation is discussed. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: "The Corps of Engineers Hydrologic Engineering Center has developed techniques that perform the spatial data analysis approach and individual structure approach and work is near completion on an integrated analysis package. The capability therefore exists to perform damage appraisals in a manner that encourages a general geographic and land use approach (thus greatly facilitating the study of nonstructural measures) while preserving the ability to analyze individual, unique structures should the need arise. This paper discusses the basic concepts of a spatial data management approach to damage appraisals and highlight(s) its integrated use with more traditional individual structure approaches. Selected example results are presented"--Page 2

Book excerpt: Over the last 15 years, The Hydrologic Engineering Center (HEC) has been developing, applying, and distributing computer programs dealing with various aspects of hydrologic engineering, including reservoir analysis. The Center has developed several models for the simulation of reservoir operation and has supported the development of a water quality model for reservoirs and rivers. This paper presents review of model development and an overview of the capabilities and types of applications for the most recent computer programs, 'Simulation of Flood Control and Conservation Systems' (HEC-5) and 'Water Quality for River-Reservoir Systems' (WQRRS). Also, current research and development dealing with reservoir analysis are described. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Water resources planning at the federal level is comprehensive multi-purpose multi-objective planning. The increasing complexity of issues, planning alternatives, and evaluation criteria have spawned an ever growing need for increased data and associated analysis procedures. The increased number of such models, both demanding and generating large amounts of data, have stimulated awareness of the need for planning oriented data management systems. This paper describes recent activities of the Corps of Engineers Hydrologic Engineering Center in data management for water resources planning studies.

Available in PDF, EPUB and Kindle. Book excerpt: The Richard B. Russell Dam and Lake Project is presently under construction and is being placed in tandem between Hartwell and Clark Hill, two existing multipurpose hydropower plants on the Savannah River. System operational simulations were performed in support of a feasibility study for the installation of pump turbines at Russell, using a version of the Corps of Engineers HEC-5C computer program modified for system power and pumped storage. Information developed from the simulations include system hydropower production, pumping energy requirements, daily reservoir pool fluctuations, and reservoir elevation statistics. This information was useful in judging the effects of the addition of pumped storage on system hydropower production and reservoir recreation useability, as well as in ascertaining efficient system operational methods.

This book was released on 1978 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two finite element hydrodynamic models, one for two-dimensional free surface flow in the horizontal plane and one for the vertical plane are being evaluated. Although the models are formulated to solve dynamic flow problems, all work to date has been with steady state solutions. Recent research has focused on mass continuity performance of the models, proper boundary condition specification, and comparison with finite difference techniques. The objective of this research is to develop generalized mathematical models for routine use by the engineering community. This paper presents recent results of evaluation and application of the models. (Author).
Download or read book Adjustment of Peak Discharge Rates for Urbanization written by David L. Gundlach and published by . This book was released on 1979 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: Various investigators have shown that changes from rural to urban conditions within a watershed, in general, significantly affect flood flows. Recorded annual peak discharge rates (or peak discharge rates above a given base) for a basin that has been undergoing a change in land-use conditions represent a nonstationary time series. The series must be adjusted to a specific land-use condition (typically present conditions) prior to performing a statistical frequency analysis. It was the aim of this note to present a procedure utilizing a single event rainfall-runoff model for transforming recorded peak discharges at a gaging station to a consistent set that reflects existing land-use conditions. Methods presented can be used as a guide to determine an existing-condition discharge frequency curve of annual peaks (or peak discharge rates above a given base) when utilizing a single event rainfall-runoff model. The multiplan-ratio option of HEC-1 permits the user to calculate systematically the hdyrologic response of several storm events for a given set of land-use conditions. The adjustment procedure described is also applicable when predicting runoff for estimated future conditions. (Author).

This book was released on 1980 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: Computer program RMA-7 has been expanded to be able to simulate density induced flows and water quality conditions typically found in deep reservoirs. The mathematical basis for the program and methods of implementing the code for various kinds of flow are discussed. Results from two different applications are presented. The first example simualtes flow conditions that were measured in a physical model of a deep reservoir. Results are also included for simulations of the circulation, temperature and dissolved oxygen concentrations for Lake Taneycomo, Missouri. Comparison of measured and computed results from both applications shows that the RMA-7 model provides reasonably accurate results for both flow circulating and water quality. (Author).
