BUILDING HYDROLOGIC FOUNDATIONS FOR APPLICATIONS OF ELOHA: HOW LONG A RECORD SHOULD YOU HAVE?

摘要

The Ecological Limits of Hydrologic Alteration framework for making regional assessments of environmental flows requires a 'hydrologic foundation' of flow data for current and undeveloped conditions. This raises the question how long a record is needed for an adequate hydrologic foundation? The answer depends on the variance in the flow record and on how much uncertainty is tolerable in metrics developed from the flow data. Copyright (c) 2017 John Wiley & Sons, Ltd.
