This book was released on 1989 with total page 103 pages. Available in PDF, EPUB and Kindle. Book excerpt: Estimates of streamflow characteristics (monthly mean flow that is exceeded 90, 80, 50, and 20 percent of the time for all years of record and mean monthly flow) were made and are presented in tabular form for 312 sites in the Missouri River basin in Montana. Short-term gaged records were extended to the base period of water years 1937-86, and were used to estimate monthly streamflow characteristics at 100 sites. Data from 47 gaged sites were used in regression analysis relating the streamflow characteristics to basin characteristics and to active-channel width. The basin-characteristics equations, with standard errors of 35 to 97%, were used to estimate streamflow characteristics at 179 ungaged sites. The channel-width equations, with standard errors of 36 to 103%, were used to estimate characteristics at 138 ungaged sites. Streamflow measurements were correlated with concurrent streamflows at nearby gaged sites to estimate streamflow characteristics at 139 ungaged sites. In a test using 20 pairs of gages, the standard errors ranged from 31 to 111%. At 139 ungaged sites, the estimates from two or more of the methods were weighted and combined in accordance with the variance of individual methods. When estimates from three methods were combined the standard errors ranged from 24 to 63% . A drainage-area-ratio adjustment method was used to estimate monthly streamflow characteristics at seven ungaged sites. The reliability of the drainage-area-ratio adjustment method was estimated to be about equal to that of the basin-characteristics method. The estimate were checked for reliability. Estimates of monthly streamflow characteristics from gaged records were considered to be most reliable, and estimates at sites with actual flow record from 1937-86 were considered to be completely reliable (zero error). Weighted-average estimates were considered to be the most reliable estimates made at ungaged sites

This book was released on 1989 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: Estimates of mean monthly and mean annual streamflow were made for 56 selected sites in the Musselshell River basin and 1 site outside the basin. The study area was divided into a Mountain Region and a Plains Region and the estimation methods were applied separately in the two regions. Four methods were developed to estimate mean monthly streamflow at ungaged sites. The first method was based on the regression relation between mean monthly streamflow and various basin and climatic characteristics. The standard errors ranged from 35 to 71% in the Mountain Region and from 98 to 157% in the Plains Region. The second method was based on the regression relations between mean monthly streamflow and activechannel width. The standard errors ranged from 38 to 81% in the Mountain Region and from 71 to 98 in the Plains Region. The third method was based on correlation of measured streamflow at ungaged sites with concurrent daily mean streamflow at nearby gaged sites. The standard errors ranged from 36 to 66 % in the Mountain Region and from 109 to 321% in the Plains Region. The fourth method, generally the most reliable, estimated mean monthly streamflows by weighing individual estimates in accordance with their variance and degree of independence. The standard error for this method when all three individual estimates were weighed ranged from 25 to 55% in the Mountain Region and from 71 to 97% in the Plains Region.

Download or read book Regional Equations for Estimating Mean Annual and Mean Seasonal Runoff for Natural Basins in Texas, Base Period 1961-90 written by Jennifer Lanning-Rush and published by . This book was released on 2000 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Regional equations were developed for estimating mean annual and mean seasonal runoff for natural basins of Texas. The equations, which are based on the statistical relation between streamflow and basin characteristics, use streamflow data and basin characteristics from U.S. Geological Survey streamflow-gaging stations within natural basins and with at least 8 years of data during 1961-90. The State was divided into 11 hydrologic regions on the basis of previous studies. The final equations for estimating mean annual and mean seasonal runoff were developed from 228 streamflow-gaging stations. Contributing drainage area and mean annual or mean seasonal precipitation were determined to be the most significant basin characteristics in each region.
