Revisiting maximum observed precipitation and discharge envelope curves

International Journal of Hydrology Science and Technology (IJHST), Vol. 10, No. 3, 2020

Abstract: Hydrologists and hydraulic engineers often require data of greatest observed point rainfall or maximum observed discharge which may occur in a river basin in order to reduce the probability of failure of large hydraulic structures. Often the envelope curves are used to estimate the extreme precipitation and floods. In the present study revised envelope curve equations have been developed for world maximum point rainfall and maximum flood in a river basin. The equations developed in the present study were found to fit the data better than previous equations. Separate equation was developed to correlate maximum observed discharge to basin area for Indian rivers.
