Abstract

This paper suggests methods for the sustainable operation of water resource use and protection. Environmental flows (EF) for rivers are used to illustrate some of the opportunities and problems inherent in managing rivers sustainably. In particular, there is a requirement for agreeing on clear and measurable environmental objectives for which a modified flow regime can be set. Knowledge from a number of different disciplines, including hydrology, ecology, hydraulics, geomorphology, water quality and socio-economics has to be integrated to provide holistic levels of understanding if sustainable management is to be achieved. Case studies from South African river research over the past 20 years are used to illustrate the policies, methods, impediments and successes of sustainable river management. In particular, a recognition of complexity and change, both in ecosystems and in human thinking and behaviour, is emphasized
