Enhanced Stage Variability on the Lower Missouri River as Benchmarked by Lewis and Clark: Implications for Ecosystem Restoration

摘要

Because lower Missouri River management began inudthe early 1800s, a challenge for present-day ecosystemudrestoration efforts is a lack of quantitative data on pre-managementudriver hydrology and long-term (100+ yr.)udriver response to changing management practice andudintensity. We address this challenge and report new resultsudfrom a study spanning 200 years of lower MissouriudRiver hydrology, encompassing natural, channelization-only,udand channelization with reservoir release regimesud(Ehlmann & Criss, Geology, forthcoming, Nov/Decud2006).
