Coastal sediment transport (a subset of sediment transport) is the interaction of coastal land forms to various complex interactions of physical processes. [1] [2] The primary agent in coastal sediment transport is wave activity (see Wind wave), followed by tides and storm surge (see Tide and Storm surge), and near shore currents (see Sea#Currents) . [1]
Coastal sediment transport takes place in near-shore environments due to the motions of waves and currents. At the mouths of rivers, coastal sediment and fluvial sediment transport processes mesh to create river deltas. Coastal sediment transport results in the formation of characteristic coastal landforms such as beaches, barrier islands, and ...
Marine sediment, or ocean sediment, or seafloor sediment, are deposits of insoluble particles that have accumulated on the seafloor.These particles either have their origins in soil and rocks and have been transported from the land to the sea, mainly by rivers but also by dust carried by wind and by the flow of glaciers into the sea, or they are biogenic deposits from marine organisms or from ...
The main focus of this program is to establish regional marine research programs around the country and to provide sustained federal funding for planned research within each region. [3] Five Major Sections of the Gulf of Maine Regional Marine Research Program: 1. An overview of marine environmental quality in the region. 2.
Coastal sediment supply is the transport of sediment to the beach environment by both fluvial and aeolian transport. While aeolian transport plays a role in the overall sedimentary budget for the coastal environment, it is paled in comparison to the fluvial supply which makes up 95% of sediment entering the ocean.

Ice rafting was a primary mechanism of sediment transport during glacial episodes of the Pleistocene when sea levels were very low and much of the land was covered by large masses (sheets) of ice. The rafting of various size sediments into deeper ocean waters by icebergs became a rather important process.
One such place is Long Beach, a small town at the southern end of a 20-mile stretch of coastline separating the Pacific Ocean from Willapa Bay. There, sediment from the Columbia River tends to ...
Sediment transportation and coastal erosion is a complex subject that is necessary to understand to protect infrastructure and the environment. [70] Coastal erosion is the process of sediment and materials breaking down and transported due to the effects of the sea . [ 71 ]
