    The flood of is the most significant flood ever recorded in east Tennessee. The Upper Tennessee Valley was especially susceptible to flooding thanks to its location between the Smoky Mountains to the east and the Cumberland Plateau to the west. TECHNIQUE FOR ESTIMATING THE MAGNITUDE AND FREQUENCY OF FLOODS IN TEXAS. Drainage area, slope, and mean annual precipitation were the only factors that were statistically significiant at the percent confidence level when the characteristics of the drainage basins were used as independent variables in a multiple-regression flood-frequency analysis of natural, unregulated .

    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:   The amount of water corresponding to a year flood, a year flood, or a 1,year flood is known as a "flood quantile". For instance, on a given river, the flood quantile corresponding to the year flood might be 10, cubic feet per second (cfs) and the flood quantile corresponding to the year flood might be 15, cfs.

If it gets any higher it will be a lot harder to deal with. Maybe about 5 more days and I can bring the truck back in.

TECHNIQUES FOR ESTIMATING FLOOD-DEPTH FREQUENCY RELATIONS ON NATURAL STREAMS IN GEORGIA By McGlone Price ABSTRACT Regional relations are defined for estimating the depth of floods having recurrence intervals of 10, 50, and years on streams with natural flow in Georgia.

Flood-frequency characteristics are defined for gaging stations in Tennessee and adjoining states having 10 or more years of record not significantly affected by man-made changes.

The flood-hydrograph and flood-volume techniques are useful for estimating a typical (average) flood. hydrograph and volume for any specified recur- rence interval peak discharge at any. ungaged stream site draining areas less than square miles in central Tennessee.

INTRODUCTION. File Size: 1MB. Tennessee is divided into four hydrologic areas (fig. The regression equations developed for these areas are for estimating peak discharges (QT) having recurrence intervals T that range from 2 to years.

Drainage area (A), in square miles, the only explanatory basin variable, can be measured from topographic maps. Flood Depth and Analysis Grids February Guidance Document 14 Page 2 used and the appropriate precision that can be supported by the data. Normally, all the raster datasets should use the same raster cell size.

However, it is strongly recommended that the cell size for the WSEL grids be no larger than 10eet x 10 feet. Tennessee Flood Hendersonville - Duration: Ben Braden Recommended for you. The Moon Through 8" Telescope - Duration: Amateur Astronomy &.

This article throws light upon the top six methods for estimation of flood discharge. The methods are: 1. Catchment-Run-Off Method 2. Empirical Formulae 3. Rational Method 4. Cross Sectional Area and Bed Slope 5.

The Flood Studies Report provided a choice of means (Fig. ) of estimating the flood hydrograph of any return period, or the estimated maximum flood, from an estimate of the storm depth and its time profile and its conversion to river flow.

Technique for estimating the 2- to year flood discharges on unregulated streams in rural Missouri. A generalized least-squares regression technique was used to relate the 2- to year flood discharges from selected streamflow-gaging stations to statistically significant basin characteristics.

Equations were developed for predicting the magnitude of floods with recurrence intervals of 2, 5, 10, 25, 50, and years in each of the six regions.

These equations are applicable to unregulated rural streams with drainage basins ranging in area from square mile to about 5, square miles in some regions. A powerful new tool for flood response and mitigation are digital geospatial flood-inundation maps that show flood water extent and depth on the land surface.

Because floods are the leading cause of natural-disaster losses, the U.S. Geological Survey (USGS) is actively involved in the development of flood inundation mapping across the Nation.
