WebThree processes have been recognised: sedimentation – settling occurs and there is no further effect on other sand particles accretion – occurs when sand grains come to a rest encroachment – the process of continued growth of sand accumulations. Once sand has accumulated it traps more and more sand, ripples turn into dunes, and dunes into ‘draa’. WebThere are four main processes of erosion that occur in rivers.
