Wake up to realities of river basin closure por Falkenmark, M., David, S.

“…However, 'quick-fix' measures such as further groundwater or surface water exploitation or ill-planned water appropriation that unfairly reallocates water from one user are common. Symptoms of poorly managed closed basins include groundwater overdraft, limited or no environmental flows, pollution and inequitable allocation of water. …”

Developing a software package for global desktop assessment of environmental flows por Smakhtin, Vladimir U., Eriyagama, Nishadi

“…The analyses can be carried out either using default (simulated) global flow data, with a spatial resolution of 0.5 degree, or a user- defined file. The package is seen as a training tool for water practitioners, policymakers and students, and as a tool for rapid preliminary environmental flow assessment.…”
