Document Summary
Large input of mud is required to form muddy shorelines. Mud can come from rivers or from the ocean. Low wave energy is required for mud to deposit. Muddy shorelines tend to be found in enclosed basins or on protected shores. Muddy shores form in inlets, behind barrier islands and on river deltas. Protect lagoon waters from wave energy, allowing mud to deposit. A coastal accumulation of river-derived sediment formed adjacent to a river mouth. Form in any body of water where river-derived sediment accumulates faster than it is dispersed. The name delta comes from the nile delta, which looks like the greek letter: not many deltas share the form of the nile delta. The niger delta protrudes smoothly from the coast. The ganges delta is dissected by numerous shore-perpendicular channels. The mississippi delta has a shape like a bird"s foot: the different delta forms arise from differences in dominant physical forcing.
