For more than a decade, the International Water Management Institute (IWMI) has been devising and steadily improving methods for E-flow assessment. In a 2007 project, IWMI partnered with World Wide Fund for Nature-India (WWF-India) to carry out the country’s first-ever holistic environmental flow assessment, focused on the iconic Ganges River.
The Indian government subsequently incorporated the concept of E-flows into the aims and objectives of the National Mission for Clean Ganga, the implementation arm of the National Ganga River Basin Authority.
