Book excerpt: After five decades, the field of Statistical Hydrology continues to evolve and remains a very active area of investigation. Researchers continue to examine various distributions, methods of estimation of parameters, and problems related to regionalization. However, much of this research appears in journals and reports and usually in a form not easi

Download or read book Estimation of Frequency Based Flood Peaks for an Ungauged Watershed Using Field Calibration written by and published by . This book was released on 1997 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Accurate estimations of flood peak, frequency, and volume are needed for safe and economical design of highway drainage and flood control structures. For watersheds with systematic stream gauging records of sufficient length, flood frequency analysis can be conducted by following the U.S. Water Resources Council (WRC) procedure [1]. The WRC procedure uses log-Pearson Type III distribution as a base method for flood frequency studies.

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: Flood frequency curves provide the annual probability of exceeding a specific flood flow. Unregulated peak flow frequencies are typically estimated based on a statistical analysis assuming floods are random homogenous events. Bulletin 17B procedures recommend a log-Pearson Type III distribution to fit a curve through observed flood data. However, such statistical analysis is inappropriate for regulated flood flows because they are affected by the flood operation of reservoirs as well as the volumes and peaks of flood hydrographs. A regulated flood frequency curve can be derived from a long unregulated period of flow record based on routing studies and developing a relationship between regulated peak outflow and unregulated inflow peak or volume, often called a peak flow transform. To resolve the interaction of peak flow rate and flood volume, a critical peak duration is often chosen, averaging flow over several days. The unregulated peak flow frequency curve, averaged over a critical duration, is then transformed to produce the regulated peak flow frequency curve. This paper examines the theoretical behavior of regulated peak transforms and provides a short case study within the Feather-Yuba river system. Two operating rules are used to simulate inflow, outflow, and storage within the reservoir and illustrate the development of a peak flow transform. These rules are: 1) optimal peak reduction with perfect foreknowledge of the flood hydrograph; and 2) minimized exceedences of downstream channel capacity. The flow transforms developed using these two operating rules seem likely to bound the range of actual peak flow transforms.

This book was released on 2008-06-27 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: The paper reviews the existing methods used in India for estimation of flow characteristics at ungauged sites. It focuses on low and high flows, long-term mean flow and flow duration curves. Since it lists the actual formulae, it can be used as a quick reference guide for selecting a suitable technique for various geographical regional and/or river basins in India.

This book was released on 1999-05-12 with total page 133 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sacramento, California, has grown literally at the edge of the Sacramento and American Rivers and for 150 years has struggled to protect itself from periodic floods by employing structural and land management measures. Much of the population lives behind levees, and most of the city's downtown business and government area is vulnerable to flooding. A major flood in 1986 served as impetus for efforts by federal, state, and local entities to identify an acceptable and feasible set of measures to increase Sacramento's level of safety from American River floods. Numerous options were identified in 1991 by the U.S. Army Corps of Engineers (USACE) in a report known as the American River Watershed Investigation. Due to the controversial nature of many of the alternatives identified in that report, study participants were not able to reach consensus on any of the flood control options. In response, the Congress directed the USACE to reevaluate available flood control options and, at the same time, asked the USACE to engage the National Research Council (NRC) as an independent advisor on these difficult studies. In 1995 NRC's Committee on Flood Control Alternatives in the American River Basin issued Flood Risk Management and the American River Basin: An Evaluation. This report outlined an approach for improving the selection of a flood risk reduction strategy from the many available.
