Urban Drainage Calculation Limits for Small Areasby David F. Kibler, Penn State Univ, United States,

Abstract: This paper discusses the selection and application of hydrologic techniques in the design of stormwater facilities, with particular emphasis on the selection of hydrologic procedure for flood peak estimation and detention basin sizing in the very small developing watershed. The study on which this paper is based was conducted for the Joint Planning Commission of Lehigh-Northampton Counties, Pennsylvania. The purpose was to develop guidelines on when to use certain hydrologic procedures for small developing areas located within the Little Lehigh Creek watershed. Because it has been analyzed extensively as part of the current basin-wide stormwater planning study of the Little Lehigh, the 12.37 square mile Swabia Creek watershed was selected as the primary test area for hydrologic calculations. The results of the hydrologic computations are discussed.
