River banks, riparian vegetation and macrophyte beds play important roles in erosion control through reducing current velocities, increasing sedimentation and reducing turbidity . Rates of flow in rivers affect inland navigation . Changing seasonality in snow-dominated basins is expected to enhance hydropower production in winter but decrease it during summer . Glacier melt changes hydrological regimes, sediment transport and bio-geochemical and contaminant fluxes from rivers to oceans, profoundly influencing ecosystem services that glacier-fed rivers provide, particularly the provision of water for agriculture, hydropower and consumption . Loss of glacial mass and snowpack has already impacted flow rates, quantities and seasonality  . Meltwater yields from glacier ice are likely to increase in many regions during the next decades but decrease thereafter, as glaciers become smaller and smaller and finally disappear .
