1247:). Some of the anthropogenic sources of modification have been put in place to halt erosion or prevent harbors from filling up with sediment. In order to assist community planners, local governments, and national governments a variety of models have been developed to predict the changes of beach sediment transport at coastal locations. Typically, during large wave events, the sediment gets transported off the beach face and deposited offshore generating a sandbar. Once the significant wave event has diminished, the sediment then gets slowly transported back onshore.

elevation will not occur during the sampling time. Once the initial benchmark is established, the researcher will take the Emory sampling device and measure the change in elevation over the distance the device is covering. Then, they will pick up the device and move it to the end point of their last survey, and so on. Until they reach the shoreline. Typically this is done during neap tide (see
1260:" From this request for research, the Office of Sea Grant reviewed, accepted, and funded the Nearshore Sediment Transport Study (NSTS). Due to unforeseen complications the NSTS conducted only two major field experiments and a validation experiment. This was a significant contribution to the field of coastal sediment transport and helped initialize a great deal of future research.

In order to determine what the profile of a beach looks like, one method for determination is the Emory Beach
Profiling Method. Initiating a benchmark, the researcher establishes a control point to start the surveys at. Typically this is far enough away from the swash zone that large changes in

In the mid-1970s a significant amount of attention was paid to coastal sediment transport. In part, due to the
National Sea Grant College Program and the U.S. Congress Mandated Sea Grant Act of 1976. One of the research areas included
1361:
Since the sand grain diameters can vary throughout the entire beach the median grain size is used to determine sediment fall velocity. Determining sediment fall velocity allows the determination of what sediment is left where.
1311:
A variety of measurements are used to determine the beach profile, sediment grain size, and various other important parameters to determine what is influencing coastal sediment transport. Below are a few of the multitude.

Models for the prediction of sediment transport in coastal regions have been used since the mid 1970s. One of the first formulas to calculate coastal sediment transport was developed by
