Heavy rains fell over the Appalachian region of Kentucky, Tennessee, Virginia and West Virginia April 2-5, 1977, causing record flooding. Rainfall amounts of 4 to 15.5 inches were observed. The maximum amount of 15.5 inches occurred at Jolo, WV , in about 30 hours. This was more than twice the amount which would be expected for a 100-year recurrence-interval storm. Flood discharges along the upper Guyandotte River; Tug Fork and Levisa Fork in the Big Sandy River basin; Cumberland River; and Clinch River and Dowell River in the Tennessee River basin exceeded those previously known. Severe flooding also occurred along the Holston River and along the North Fork Kentucky River. Recurrence intervals of observed flood discharges were greater than 100-years at 29 streamflow measurement sites. Substantial reductions in peak stages and discharges on Levisa Fork, North Pound River, and Guyandotte River, attained as a result of reservoir storage, were reported...

On 12 September 1977, severe flash flooding in Kansas City, Mo., resulted in widespread damage and 25 fatalities. It was the worst flash flood of modern times in this area in terms of loss of life and damage. Meteorological analysis of the flood situation indicates the key ingredients for the unprecedented flooding were: 1) two heavy convective rain events occurring in essentially the same location within a 20 h period, and 2) the formation by the first storm system of a small-scale surface boundary wave that concentrated the low-level convergence over the Kansas City area for an extended period of time preceding the second event. Total rainfall amounts for the 24 h storm period were >16 inches (40 cm). Rainfall rates were as high as 8 inches (20 cm) in 4 h during the flooding on the evening of the 12th. Besides the conventional surface and upper air observational network, radar and satellite input were of significant value in analyzing the storm evolution.
