<br />ABSTRACT <br /> <br />. <br /> <br />, <br /> <br />Dams are subject to failure and the damages produced by the result- <br />ing flood are extensive. Alleviation or prevention of the damaging <br />effects requires the knowledge of the flood characteristics. These <br />include primarily the time of arrival of the flood-wave front. the <br />maximum flood level and the time at which the maximlll1 flood level occurs <br />after dam failure. <br /> <br />Using a rational computation technique. based on the method of <br />characteristics. dimensionless ~raphs of the aforementioned flood <br />characteristics were prepared for a prismatic channel of general para- <br />bolic cross section and several values of the parameters involved. These <br />values were selected to cover the practical range of the field conditions <br />affecting the magnitude of the dam-break flood. Results were obtained <br />for such periods of time that the flood peak advanced adequately down- <br />stream and either subsided or stabilized considerably. <br /> <br />y~y WORDS: Dams; Floods; Graphs; Hydraulics; Rivers; Waves. <br /> <br />, <br /> <br />i i <br />
