Abstract:
This study is a review of overseas approaches to setting River Flow Objectives. It has been compiled to enable the Environment Agency to learn from international operational experience in order to develop its policy on setting River Flow Objectives (RFOs), and ultimately, statutory Minimum Acceptable Flows (MAFs). The review follows Agency R&D Note 449 in categorising the methods into four levels, look up table, desktop analysis of historical data, collection and. descriptive analysis of primary field data and flow-habitat-biological response simulation. There is a clear difference in the resources required to move from stage to stage. Drawing on documented experiences overseas, the potential advantages and disadvantages of River Flow Objectives have been briefly reviewed. Major issues are the processes used in their determination, resources required and their defensibility. Their role in moving towards sustainable development is highlighted. At the policy level, the characteristics that appear to relate to the success of such methods are also reviewed.
