Criteria for river regulation (environmentally acceptable flows) and conservation
Over the last decades the list of social and environmental disasters has led to general acceptance of the need for reevaluation of management concepts and methods. Scientists have moved to focus on large rivers and large water projects which may be large dams or large-scale interbasin transfer on a complex system of interconnected small water works. The modification of the natural flow regime through storage and abstraction has adverse impacts on aquatic biota, recreational uses, maintenance of assimilation capacity for effluents, and navigation. The continuous development of Environmental Impact Assessment is producing more rationale approaches to evaluate new proposal and the development of monitoring systems in providing for improved post-project appraisal in order to mitigate water uses conflicts. The objective of this report is to compare the different approaches for the determination of 'ecologically acceptable flow' (minimum flow for supporting different water uses) in order to advance the development of environmental sound management policies and strategies.
