Low-salinity water from the Ganga-Brahmaputra river is transported by mesoscale eddies in the Bay of Bengal, but when the monsoon winds strengthen, a shallow “Ekman” flow dominates dispersal of water.

Insensitivity of Total Sediment Flux to Hydraulic Details
The total sediment mass transported by flow under different sets of regimes is insensitive to the exact details of hydraulic forcing, but what matters is cumulative transport capacity.
