POND SIZING FOR RATIONAL FORMULA HYDROGRAPHS1 |
|
| Authors: | Gert Aron David F Kibler |
| Abstract: | ABSTRACT: The Modified Rational formula hydrograph and the Yarnell generalized rainfall chart are generally accepted procedures for sizing storm water detention ponds for small drainage areas. A procedure has been developed to choose the rainfall duration which, for a chosen return period, will result in the largest required storage volume of a detention pond. A graphical solution has been provided and its use has been described by application to an example. |
