Melting ice may change shape of Arctic river deltas
Thawing ice cover and easily erodible permafrost may destabilize Arctic river deltas, according to new research. A new study in the AGU journal Geophysical Research Letters finds sea ice and permafrost both act to stabilize channels on Arctic river deltas.

Mountain glaciers recharge vital aquifers
Small mountain glaciers play a big role in recharging vital aquifers and in keeping rivers flowing during the winter, according to a new study. It suggests that the accelerated melting of mountain glaciers in recent decades may explain why arctic and subarctic rivers have increased their water flow during the winter even without a correlative increase in rain or snowfall.

After canals go in, fish diversity goes up… many millenia from now
Facing a growing population and increasing demands for fresh water, India is hoping that an engineering fix will help solve its water-scarcity problems. The country’s National Water Development Agency has begun work on the first of a system of 30 canals that would link 46 rivers, in a process known as inter-basin water transfer.
