Abstract

Design of hydraulic structures, optimal operation of reservoirs, and flood forecasting involve estimation of flood flows x^,, with given specified return period T. This estimation is generally achieved by fitting a probability distribution to observed data. In this paper, we briefly present some recent theoretical results of a study on Halphen distributions which were developed in the early forties but have been little used due to the computational complexity. This family of three distributions was motivated by Halphen's desire to construct probability models which met specific requirements of fitting hydrological variables. Halphen probability models have great potential applicability in statistical flood analysis but are not yet fami
