This report presents techniques for estimating peak-flow frequency relations for North Dakota streams. In addition, a generalized skew coefficient analysis was completed for North Dakota to test the validity of using the generalized skew coefficient map in Bulletin 17B of the Hydrology Subcommittee of the Interagency Advisory Committee on Water Data,"Guidelines for.
This method is most valid in situations where watersheds are of similar size, land use, soil types, and experience similar precipitation patterns. Discharge is estimated by drainage area weighting using the following equation: gaged gaged ungaged ungaged A Q Q A = × where Qungaged: Flow at the ungaged location Qgaged: Flow at surrogate USGS.

Sanocki. Full text of "Flood flow frequency for ungaged watersheds: a literature evaluation" See other formats. Techniques for estimating peak flow on small streams in Minnesota by D.L. Lorenz, G.H. Carlson, and C.A. Sanocki ABSTRACT Two statistically-derived techniques, regional regression equation and region of influence regression, that estimate peak flow on small, ungaged streams in Minnesota were developed.
Both techniques relate. Regional regression equations have been developed and are used extensively to estimate annual peak-streamflow frequency for ungaged sites in natural (unregulated and rural or nonurbanized. The method was incomplete, however, since it lacked a working method of estimating the time parameter for ungaged watersheds.
Therefore, the first objective of this study was to satisfy this need. The second objective was to test the overall method as a means of predicting peak flow for small ungaged watersheds, given the runoff by: 1.
Estimating Peak Flow Frequencies for Natural Ungaged Watersheds – A Proposed Nationwide Test. Hydrology Committee, Washington, D.C., pages. Google ScholarCited by: 1. Overview of NSSThe U.S. Geological Survey (USGS) develops and publishes regression equations for estimating streamflow statistics for every State, the Commonwealth of Puerto Rico, and a number of metropolitan areas in the United States.
These equations have been compiled into the National Streamflow Statistics (NSS) Program. The NSS program. Peak flow data are collected at gaging sta tions. Flood peaks at gaging stations are an alyzed by the annual flood series method in which only the maximum peak discharge for each year is used, as contrasted with the pa rtial duration series method in which all peaks higher than a selected base are used without regard to the time of occurrence.

A practical method is suggested for estimating the peak flow. The variables used are the mean daily flows of three consecutive days with the maximum mean daily flow occupying the middle position.
A parameter, designated as base factor K, has. This involves estimating the mean annual peak flow for a particular site on the basis of local information and its coefficient of variation on the basis of regional information.
Annual peak flows can be estimated from the stream geometry or by measuring the peak water levels upstream of existing culverts, which have entrance controls, as do.

When designing a structure (such as a bridge or culvert) within the flood plain of a river or stream, it is necessary to estimate the peak flood flow so that the structure can be built to accommodate that flow.

SW Describes revisions made to the annual flood-frequency analysis program (J) to conform with new WRC guidelines.
