Get this from a library. Assessment of peak discharge uncertainty in the American River Basin, California. [Robert W Meyer; United States. Bureau of Reclamation.; Geological Survey (U.S.)]. Flood-discharge data, current-meter and indirect measurements, and stage-discharge relations, the oldest of which dates to the early 's, were used to estimate the uncertainty about annual flood peaks in or near the American River Basin at 20 stream-gaging stations operated by the U.S.
Geological Survey. The study estimates that, in the study area, most flood peaks that were. Due to unavailability of sufficient discharge data for many rivers, hydrologists have used indirect methods for deriving flood discharge amount, that is, application of channel geometry and hydrological models, for the estimation of peak discharge in the selected ungauged river basin(s) in their research/project works.
This paper has studied the estimation of peak flood discharge of the Kunur Cited by: measurement quality of poor (uncertainty plus or minus 25 percent or greater).
The peak discharge of the Augflood at the Fountain Creek site was 5, ft 3 /s with a measurement quality of poor (uncertainty plus or minus 25 percent or greater). The Augflood at the Big Cottonwood Creek site had an annual exceedance probability of less than (return period. This study quantifies the uncertainty in discharge calculations caused by uncertainty in precipitation input for river basins worldwide.
Seven global gridded precipitation datasets are compared at river basin scale in terms of mean annual and seasonal by: Using a geology-based assessment method, the U.S. Geological Survey estimated means of trillion cubic feet of undiscovered natural gas, million barrels of undiscovered oil, and million barrels of natural gas liquids in the Powder River Basin Province.
“The computed discharge is the maximum that can occur for the selected rainfall intensity from that basin and that discharge occurs at the time of concentration and beyond.” 2.
“The peak river flow is directly proportional to rainfall.” 3. “The frequency of the peak discharge is the same as the frequency of rainfall" (see above). estimating storm peak discharge, unit-hydrograph peak discharge, and unit-hydrograph lag time.
A final component of the procedures is the development of a dimensionless unit hydrograph developed from streamflow and rainfall data collected during the – water years at 25 streamgaging stations and up to 60 raingages in the city and county.

was chosen as the example year, and you can see what was the daily average of water discharge (in m 3 /sec) for each model pixel of roughly 55 x 55 km. A logarithmic color scale was used because discharge in the headwaters can be orders. This paper aims at analysing and quantifying the uncertainty that may be present in river discharge records.
A numerical analysis was performed on a km reach of the Po River (Italy). The results show that errors in river flow data are indeed far from negligible. immediately north of Detroit in the Clinton River basin The study was conducted to determine peak- discharge frequency curves at two gaged and numerous ungaged locations for existing () land use con- ditions as well as for conditions in the years and Methodology is reported herein for con.

The Colorado River Basin: An Overview Executive Summary The Colorado River Basin: The basin is located in the southwestern US and occupies an area ofsquare miles. The Colorado River drains the Basin, running some 1, miles from “source to sea”.

More thanpeople and $37 billion worth of damageable property are vulnerable to flooding in the area, including most of the city's central.

in the basin, resulting in higher and earlier peak flows and lower summer flows for many locations across the CRBIA. A comparison is being initiated with earlier climate change work, specifically the River Management Joint Operating Committee-I (RMJOC-I) study, which used Coupled Model.
The 2- 5-,and year peak discharges were estimated for streamflow-gaging stations with at least 8 years of data for natural streams in and near the Brazos River Basin, Texas.
Multiple regression equations were developed to estimate peak-discharge frequency for the 2- 5-,and year recurrence intervals for each of three hydrologic regions that compose.

Contiguous U.S. Major River Basins as designated by the U.S. Water Resources Council. The National Rivers and Streams Assessment (NRSA) report provides information on the biological and recreational condition of the nation’s rivers and streams and the key stressors that affect them.
It also reports out on changes in stream condition compared to an earlier study, the Wadeable Streams Assessment. Background: During the summers of and85 field crews. The application example was conducted with flood data from the American river basin, near the Folsom reservoir, in California, USA.
The results show that it is possible to put together concepts that appear to be incompatible: the deterministic estimate of PMF, taken as a theoretical limit for floods, and the frequency analysis of maximum flows. Colorado River Basin Water Supply & Demand Study Hydropower Western, CREDA.

Each basin in the watershed model uses the same core hydrologic model components within the National Weather Service’s River Forecast System (NWSRFS). Previous American Watershed Model Previously, the operational American River model did not directly model the effect of the upstream reservoirs.
Only full natural flow (FNF) was modeled. Inthe committee issued Flood Risk Management and the American River Basin: An Evaluation (NRC, ), a report that outlined an approach for improving the selection of a flood risk reduction strategy from the many available.

The oxygen isotope values (δ.

River regulation materially affects the magnitude of peak flood discharge in a river basin. Peak flow in the upper Colorado River basin is primarily from snowmelt runoff. The first significant regulation occurred in with the inauguration of the Moffat Tunnel and.
