Download or read book Development of Generalized Free Surface Flow Models Using Finite Element Techniques written by D. Michael Gee and published by . 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).

Available in PDF, EPUB and Kindle. Book excerpt: A case study is presented of a hydrologic investigation of the Red Run Drain-Lower Clinton River watershed, an area near Detroit, Michigan, that has undergone urbanization since the 1940's. The purpose of the study was to determine peak-discharge frequencies at gaged and ungaged locations for existing and future conditions. Population density was used as an indicator of urbanization in relationships defining unit hydrograph parameters and hydrologically significant impervious area. Input parameters for a single event rainfall-runoff simulation model (HEC-1) were developed to reflect watershed conditions in the years 1940, 1950, 1960 and 1975. The input parameters were verified by reconstructing observed flood events that occurred at these points in time. Sets of synthetic winter and summer storm hyetographs were input to HEC-1 to develop a series of curves for two gaging stations that relate peak discharge to magnitude of synthetic storm for each watershed condition. The curves were used to transform the series of recorded annual peak discharges at each gage to a stationary series that reflects 1975 watershed conditions. Discharge frequency estimates were then developed for ungaged locations using winter and summer synthetic storms that were assigned exceedance frequencies consistent with actual exceedance frequencies at the gaged locations. Projections of future population density were the basis for developing HEC-1 input parameters representing year 2000 and 2025 watershed conditions. Estimates of peak discharge-frequencies for the future conditions were made at the gaged and ungaged locations using the methods described above. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The Hydrologic Engineering Center, Corps of Engineers, is preparing a document entitled 'Manual for the Determination of the Feasibility of Adding Small Hydroelectric Power to an Existing Facility.' The manual is designed for use by public agencies (federal, state and local), public and private utilities, and private investors. It focuses upon the concepts, technology, and economic and financial issues unique to small hydropower additions. This paper discusses issues related to engineering and economic considerations in planning small hydropower additions, presents an overview of significant findings of the investigation to data, and provides a status report on manual preparation.

This book was released on 1980 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: A land use/land cover identification methodology using LANDSAT imagery has been applied to six watersheds across the U.S. The land use information is stored in a grid cell data bank and is the basis for calibration of hydrologic parameters for watershed models. Flood frequency studies have been completed on four of the watersheds with land use derived from both satellite data and conventional low altitude aerial photography. This paper discusses our experience using the LANDSAT land use classification procedure and compares hydrologic results obtained from the alternative determinations of land use. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The application of the Soil Conservation Services (SCS) urban hydrology techniques is made to four watersheds. The parameters of the methods are obtained from standard SCS guidance and from calibration of watershed model HEC-1 using the SCS method. A modified method of determining these parameters is also recommended to SCS. Runoff parameters are then used with design storms to illustrate the differences in frequency curves which may result.

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.
