Environmental Flows describes the timing, quality, and quantity of water flows required to sustain freshwater and estuarian ecosystems and the human well-being and livelihoods that depend on them. It answers crucial questions about the flow of water within and between different kinds of ecosystems. What happens when the flow or the availability of water is curtailed or diverted, either naturally or by human activity? How will climate change alter the availability of water and impact the aquatic ecosystems? Covering methodological developments from the simplest hydrological formulas to large-scale frameworks that inform water management, this book is a must-read for water managers and freshwater and estuarian ecologists contending with ever-changing conditions influencing the flow of water. -- Book Jacket.
