Environmental Flows

Converting recommendations from environmental flow assessments into management actions that produce the desired river flow regime has lagged behind the assessment process in most countries. Two major forms of regulatory process may be involved in the provision of an environmental flow regime, known as restrictive (e.g., sustainable diversion limits, or “caps,” on further abstraction) and active (e.g., ecologically appropriate flow releases from reservoirs). Water release strategies for irrigation, hydroelectric, and flood control dams, and methods for managing water abstractions are reviewed. Implementation must go hand in hand with appropriate monitoring arrangements to assess compliance and ecological effectiveness. Flow restoration projects can be viewed as ecological experiments that can improve knowledge of hydro-ecological relationships and support water management within an adaptive management framework.

Keywords:   implementation, regulatory processes, sustainable diversion limits, flow releases, monitoring, ecological experiments, adaptive management
