HS9.1.4

Transport of sediments due to the action of geophysical flows occurs in fluvial, estuarine, aeolian and other natural or man-made environments on Earth and has been shown to play important formative roles in planets and satellites such as Mars, Titan, and Venus. Understanding the motion and the causes of motion of sediments is still one of the most fundamental problems in hydrological and geophysical sciences. Such processes can vary across a wide range of scales leading to sediment transport and scour which can directly impact both the form (geomorphology) and, on Earth, the function (ecology and biology) of natural surface water systems and the built infrastructure surrounding them. In particular, the feedback between flow and sediment transport is a key process in surface dynamics, finding a range of important applications, from hydraulic engineering and natural hazards protection to landscape evolution and river ecology.

We welcome specific topics of interest that include (but are not restricted to):
-particle-scale mechanics of particle entrainment and disentrainment
-upscaling and averaging techniques for stochastic processes related to granular processes
-interaction among grain sizes in poorly sorted mixtures, including particle segregation
-momentum/energy transfer between turbulent flows and particless
-derivation and solution of conservation equations
-reach scale sediment transport and geomorphic processes
-shallow water hydro-sediment-morphodynamic processes
-fluvial processes in response to reservoir operation schemes
