Abstract

Shoreline changes indicate dynamic events in coastal areas. Communities around the coast will feel the impact of changes in the coastline. The purposes of this study are (1) to analyze the level of shoreline change from 2015 to 2021 and (2) to analyze the effect of tidal flooding on shoreline changes in Sayung District, Demak Regency. This study used descriptive qualitative analysis and the Normalized Different Water Index (NDWI) method and conducted accuracy and validity tests. Analysis of tidal flooding is a factor that influences shoreline changes by using an analysis of the distribution of affected areas so that areas that often experience tidal flooding can be identified. (1) The results of this study are significant abrasion and accretion from 2015 to 2021 in a coastal village with a beach length of 20.9 km which has experienced 122.14 Ha of coastal abrasion and 17.53 Ha of accretion with an abrasion percentage (86%) and accretion (14%). Overall rate of abrasion (17.44 Ha/year) and accretion (2.50 Ha/year). (2) Tidal flood areas that occur in coastal areas result in areas that are eroded or sea level rise causes changes. The immigration process for coastal residents will be carried out to maintain their economy and life because living in coastal areas that are prone to changes in the coastline will harm them, especially for their daily needs. Local governments need to routinely and provide material assistance to underprivileged citizens for immigration in appropriate places.
