Environmental flow assessment, evaluation, and suggestions for dying riverine ecosystem of the transboundary Amudarya River, Central Asia

First study generated naturalized streamflow and assesses environmental flow for all tributaries of the Amudarya River. The estimated environmental flow ranged from 25 to 46% of naturalized mean annual flow (MAF) for all tributaries. Current environmental flow (2–5% of MAF) is extremely lower than the estimated one for the delta region. Environmental conditions are severely damaged in the middle and lower reaches.
