Abstract

This study aimed to compare the shoreline change occurs by combining the two coastlines and five shoreline with a different time using DSAS so as to identify and measure erosion (shoreline retreat) and accretion (shoreline advance) that occur shoreline at the beach Tuban. Shoreline change rates were calculated according to Net Shoreline Movement (NSM), End Point Reference (EPR), and Linear Regression Rate (LRR). The result of DSAS analysis using 2 shorelines (from 1972 to 2015) indicated shoreline retreat with average EPR of 15.25 m/year and average NSM of 650.11m. However, the same analysis using 5 shorelines for the same time period indicated shoreline retreat with average EPR of 15.23 m/year and average LRR of 13.86 m/year. Merge using two shoreline in different time shows the results of a more detailed and very clear so it can be known with certainty at the transect lines which indicate the presence of shoreline retreat and shoreline forward but can not see the trend when compared to combining 5 shoreline.
