Mr. Bhopal Singh

Absence of an acceptable definition of environmental needs and, also, the absence of an agreement on the priority of environmental flow releases. There is lack of both the understanding of and availability of quantitative data on relationships between river flows and ecological characteristics of river. While the domestic and agriculture requirements are easily quantifiable, it is still a challenge to decide as to what comprises the legitimate ecological needs— wide variations in assessment of E-flows by different methods/agencies.
