Process:  - Sediment transport is the movement of solid particles (sediment) - The movement is due to a combination of gravity acting on the sediment, and/or the movement of the fluid in which the sediment is entrained - Sediment transport occurs in natural systems where the particles are clastic rocks (sand, gravel, boulders, etc.), mud, or clay - The fluid is air, water, or ice - And the force of gravity acts to move the particles along the sloping surface on which they are resting - Sediment transport due to fluid motion occurs in rivers, oceans, lakes, seas, and other bodies of water due to currents and tides - Transport is also caused by glaciers as they flow -   Perturbation hypothesis: suppose water has stronger currents happens, how will it affect less sediment will travel.  Does the supposed perturbation have an effect (direct or indirect) on the process?

yes
