Article Writing Homework Help

Need help with my writing homework on Decadal Sand Bar Behavior. Write a 1000 word paper answering; Tough availability of the material is of equal importance in forming a sand bar. the size of the material of the Sand Bar depends on the size of the waves or the strength of the material.

As a bar is merely a disposition of material by the water, in case of vessel grounding on these bars is worse off than grounding on stationary rocks. This is because of the more destruction caused by the shifting action of these materials.

These bars can spread over a considerable range in size and length, from just a couple of meters in a small stream to large depositions stretching over hundreds of kilometres along a coastline, commonly known as barrier islands.

Long shore currents or even fluvial currents in the shallow water coastal environments are responsible for the construction of submerged bars. These bars are strongly determined by the amount of unused sediment available along a shore. These sediments along the shore are called its “sand budget” and determine the number of bars that form along the coastline. The types of submerged bars and the orientations and shapes are controlled by the way the sediments are transported through the shore zone.

Along the shoreline which is mostly dominated by waves, the shore current carry and deposit the sediments along the shore face in parallel bars to the shore.
