    Techniques for estimating magnitude and frequency of flood-peak discharges, based on channel geometry parameters, are presented as a method for evaluating Ohio floods in geographic areas deficient. This report describes the results of a study to estimate the magnitudes of peak flows for ungaged, unregulated steep streams in New England. Regression relationships are presented which relate basin and climatic characteristics to peak flows for recurrence intervals of 2, 5, 10, 25, 50, , and years. In addition, this report describes the.

    The estimation of the peak river flow, like the estimation of any design variable, requires the specification of assigned design details. In particular, the peak river flow depends on the return period, which defines how much a peak flow is "extreme".In statistics and engineering we can quantify the "extremeness" of an event by specifying its frequency of occurrence.

Technique for estimating magnitude and frequency of peak flows in Maryland by Jonathan J. A. Dillow Download PDF EPUB FB2

Methods are presented for estimating peak-flow magnitudes of selected frequencies, ranging from 2 to years, for all nontidal drainage basins in Maryland. The methods were developed by generalized least-squares regression techniques using data from gaged basins.

Background Techniques for estimating peak-flow frequen­ cies for Delaware streams were previously pre­ sented in reports by Tice () and Gushing, Kantrowitz, and Taylor (). The most recent technique for estimating peak-flow frequencies in Maryland was presented by Simmons and Carpen­ ter ().Cited by: Technique for estimating magnitude and frequency of peak flows in Maryland.

Regression equations for estimating the magnitude and frequency of floods on ungaged streams in Pennsylvania with drainage areas less that 2, square miles were developed on the basis of peak-flow data collected at streamflow-gaging stations.

A method is presented for estimating peak-flow magnitudes and frequencies at ungaged sites. Multiple-regression techniques are used to develop equations which relate physical and climatological features of drainage basin to peak discharges for selected recurrence intervals, from 2 to years.
