Flood frequency analysis


  • C. J. Posey


Panattoni and Wallis' treatment of the flood frequency analysis problem i s masterful; one hopes that its appearance will put and end to the proliferation of naive efforts to establish a nonsubjective statistical method. Their treatment of the systems analysis phase of the problem makes use of the latest computational techniques, but one doubts that the results could be superior to those reached by the engineers who designed the river control system built by the Miami Conservancy District between 1913 and 1918 and described in its Technical Report, Part VII. Records on the operation of the project, kept for more than 50 years, should provide an opportunity to test whether Panattoni and Wallis' technique of using the roughness coefficient as a fitting parameter is a valid approach.
