Summary

This chapter discusses the impact of river engineering on natural flow regimes and the attendant effects on ecosystems. Changes in flow regimes have resulted in huge ecological change, including the creation of exotic species that replace or compete with the native species. Many rivers in arid regions have growing populations and economic activity dependent on their water supplies. Restoring natural flows may not be possible.
