Flood of February 1989 in Kentucky

Abstract

Cubic foot per second (ft s /s) is the rate of discharge representing a volume of 1 cubic foot passing a given point during 1 second and is equivalent to approximately 7.48 gallons per second. Gage-height is the water-surface elevation referred to some arbitrary gage datum. Gage height is often used interchangeably with the term stage. Gaging station is a particular site on a stream, canal, lake or reservoir where systematic observation of water surface elevations and/or discharges are determined. Recurrence interval of a flood or frequency is the probability, expressed in years, that a particular flood event may occur. Gage heights of selected gaging stations throughout this report are referenced to a station datum which is described in the annual series of "Water Resources Data for Kentucky" published by the U.S. Geological Survey.
