A mathematical and numerical model of the joint dynamics surface water traction sediment is built, which takes into account nonlinear fluid bottom deformation. The waters described by equations Saint-Venant, taking spatially inhomogeneous distribution terrain. transport loads Exner equation, generalized to case a parameters underlying surface. For integration Saint-Venant equations, stable well...

Active colloids are self-propelled particles moving in viscous fluids by consuming fuel from their surroundings. Here, we review the numerical and theoretical modeling of active propelled self-generated near-surface flows. We start with generic model an Brownian particle taking into account potential forces effective pairwise interaction, which include hydrodynamic phoretic interactions. Also, ...
