Abstract:

Paleoflood hydrology is the study of botanic, sedimentologic and geomorphic flood evidence remaining in a valley. Paleoflood studies in the Colorado foothills and mountains have been used to determine maximum flood flows back to the end of the ice age, some 10,000 years ago. Such determinations can be made in other geographic locations. The results are useful in dam spillway design and risk analysis, and can be used as an independent means of confirming or correcting past accounts of extreme flood and precipitation events.
