Abstract

A geological approach to palaeoflood analysis is demonstrated. The most useful data for geological flood frequency analysis come from confined bedrock canyons in which relatively small discharge variations produce relatively large changes in stage. The Lower Pecos River of western Texas contains several sites with correlative slack-water sequences for 10-12 major flood events. The data show that the Pecos flood of 1954, which was nearly an order of magnitude larger than any other in 40 years of record, had a recurrence interval of 2000+ years.- from Authors
