GLOSSARY

Adaptive management process
Adaptive management promotes an environment for testing hypotheses and exploring promising changes based on sound scientific data and analyses. For the Master Manual process this means monitoring and evaluating actual physical and biological responses to changes in management of the system and then adapting new management strategies based on the additional information.

Evapotranspiration
Water transferred from water bodies or soil to the atmosphere through evaporation or transpiration. 

Flow exceedance percentiles
Calculated percent of the time that a given flow is equaled or exceeded. 

Flow frequency
How often flows occur in a given time-period.  For the purposes of this report, flow frequency is calculated as a flow-exceedance percentile for each day of the year.

Water control rules
A set of rules for how reservoirs are operated to achieve the purposes for which the Missouri River is managed such as navigation, flood control, hydropower production, drought conservation, reservoir unbalancing, and environmental objectives.
