ANALYSIS OF THE U. S. GEOLOGICAL SURVEY STREAMGAGING NETWORK.

This paper summarizes the results from the first 3 years of a 5-year cost-effectiveness study of the U. S. Geological Survey streamgaging network. The objective of the study is to define and document the most cost-effective means of furnishing streamflow information. In the first step of this study, data uses were identified for 3,493 continuous-record stations currently being operated in 32 States. In the second step, evaluation of alternative methods of providing streamflow information, flow-routing models, and regression models were developed for estimating daily flows at 251 stations of the 3,493 stations analyzed. In the third step of the analysis, relationships were developed between the accuracy of the streamflow records and the operating budget. The existing streamgaging networks in four Districts were further analyzed to determine the impacts that satellite telemetry would have on the cost effectiveness. Satellite telemetry was not found to be cost effective on the basis of hydrologic-data collection alone, given present cost of equipment and operation.

Interim report on the investigation of flooding in the Tug Fork basin of Kentucky, Virginia, and West Virginia

An analytical plan is presented for a study of the effects of land-use changes on the magnitude and frequency of flood-peak flows and on sediment characteristics of the Tug Fork in Kentucky, Virginia, and West Virginia. The plan includes compilation and analysis of available data, collection of new data on small, single land-use drainage areas for deterministic computer modeling, and creation of a computer model of the Tug Fork basin for definition of cumulative land-use impacts. Also presented is a compilation of the available hydrologic data and a description of related studies expected to provide information and data useful to the ongoing work. The data compilation includes: Hourly precipitation for selected days and annual maximum daily precipitation for nine sites, annual maximum streamflow rates and stages for three stream-gaging sites, hourly gageheight and discharge rates for selected storms at four stream-gaging sites, flood profiles, flood-frequency relations, and other streamflow information.

Flood discharges of streams in New Mexico as related to channel geometry

This report describes the results of a study relating flood characteristics to the reference width of the channel. Data from 79 gaging stations, which would provide estimates of floods of a 10-year recurrence interval and at which channel geometry could be adequately measured in the field, were used in these analyses. The peak discharges for recurrence intervals of 2, 5, 10, 25, and 50 years were determined for each station and are given in tabular form where appropriate. Features that define the reference width vary with location and stream type. A discussion is given of the features that were used in measuring reference widths. The relation between the magnitude of floods of various frequencies and the reference width and main-channel slope was reliable with a standard error of about 65 percent for most of the areas of the State; however, no reliable relation could be found for many stream channels in a large area of southeastern New Mexico, and it is recommended that the relation not be used in that area. The reasons for this difficulty is believed to be due to recent channel entrenchment in the area.

Preliminary flood-frequency relations and summary of maximum discharges in New Mexico; a progress report

The magnitude and frequency of floods is defined regionally for streams in New Mexico. An analysis was made, using multiple- regression techniques, relating flood peaks of 2, 5, 10, 25, and 50-year recurrence intervals to selected physical and climatic basin characteristics. The state was divided into three flood regions, and the resulting equations and associated standard error of prediction are presented for each of these regions. In addition the maximum observed discharges at regular and crest-stage gaging stations, and all peak discharges by indirect measurements at miscellaneous sites are presented in tabular and graphical form. The equations developed in the study can be used to compute peak discharges of floods of given recurrence intervals for use in the design of drainage structures.
