Item Open Access An Analysis of the Correlation between Shoreline Curvature and Shoreline Change along the Gulf of Mexico and the Mid-Atlantic Coast of the United States(2016-04-26) Cheng, Yeeyan (Scarlet)Increasing human development along the coast, together with climate change and sea level rise, has drastically changed the shape of the coastline. Because of the widespread impacts of shoreline change, studies have been conducted by USGS and various researches, in attempt to understand shoreline change rates and its connection to local, regional, and global factors. However, one of such factor, shoreline curvature, is not well-addressed in current literature. As a continuation of work that was conducted by another student last year, the main objective of this project is to expand the scope of the study by examining the shorelines of Texas, and the rest of the East Coast (up till Long Island at New York) of the United States. More importantly, this study aims to investigate how different temporal and spatial scales contribute to different strength, or even direction of the correlation between shoreline curvature and shoreline change.Item Open Access Shoreline Change on the East Coast: Exploring the Role of Shoreline Curvature(2015-04-24) Liu, JiahongThe low sloping sandy shoreline of the East Coast is one of the most dynamic and complicated systems influenced by a series of factors. Shoreline curvature has been mentioned in several pieces of literature as one of these factors, as it influences the shaping processes of the shoreline through affecting the alongshore sediment transport. However, only a few quantitative research or evidence has been provided to show the curvature influence on shoreline change rate. Using the coastline contour data of the east coast, the curvature has been calculated and smoothed on different scales (1-km, 3-km and 5-km) in this project. The results of correlation analysis of selected shoreline segments in Florida and North Carolina indicate the existence of a significant correlation between curvature and shoreline change rate. The greatest coefficient was observed on the 3-km scale of selected shoreline segments, which is similar to previous foundings. The results also show that the strength of correlation varies from one location to another.
