Introduction Beach morphology is a key factor in helping determine the sediment interaction between not only the ocean but the surrounding environment as well. On September 23rd, 2016 at 1500-1645 hours’ group 3 of MSCI 112 collected local data of the morphology of Myrtle Beach State Park, SC, US. With the help of the data collected on site as well as the data collected in the lab our main objective is to able to learn more about the impact on the beach as well as the interactions it has with the environment.

Longshore Transport At 1600 hours, using grapefruits, a measuring tape and a stop watch, we measured the average velocity of the waves in duplicates. After the two trials the average velocity of the transport was .35 Knots to …show more content…
By the time we took the measurements the tide was in its ebbing phase as well an incoming storm was heading its way towards us too which would have an effect on the wind direction as well as cause some interference with wave directions as well. With the change is weather I did affect our data but it also helped show how much of an impact the environment has on the beaches and how a simple storm can change everything.
Beach Profile While taking down the data measurements for the beach profile were tedious, when we finally graphed the data it helped create a better image of the beach as well as factor in how tides and the incoming waves influence the curvature of the beach. Coinciding with the data from the longshore transport the beach profile also helps show the ever changing environment of the beach and its surrounding areas. …show more content…
While the dunes had more fine grain size than the swash both were the highest percentage. This shows that from a basic point of view that both areas have similar grains. But when you look at both microscopically you can tell that when compared they’re not even close to being similar. While they are both the same size the dunes sand has endured more erosion due to their well sorted and fine sized size this can be due to the amount of time they have been transported and deposited due the waves. While the swash zone has and is currently enduring the waves as well what makes it so different is that the grains in the zone have not has as much time with wear as the dunes have making the grains coarse but another factor is the constant wash up of Biogenous minerals like shells making the swash zone poorly
