Special Session - Developing Flow-ecology Response Relations to Support Regional Streamflow Management I
Environmental or ecological flows have become a topic of heightened national and international interest over the past decade as the need to better understand how human modification of natural streamflow variability affect water availability and aquatic assemblages has expanded. There is a growing interest in streamflow management among regulatory agencies in developing regional flow standards but the science to support such standards is still being developed. Recent advances in environmental flow science have emphasized the need to quantify ecological responses to flow alteration and to examine how these responses vary among streams that differ in their natural flow regimes. This special session will present current research and advances in quantitative methods currently being used throughout the international community to develop a basis for establishing flow-ecology response relations. It will strive to bring together scientists working in diverse streams and rivers to compare and contrast methods that are applied in broad geographic settings for different aquatic assemblages and ultimately, better inform water resource managers, planners, and policy makers on what does and doesn’t work for setting environmental flow standards at the state, provincial, and regional levels.
