Abstract

Tidal flood is a phenomenon of sea level rise with a water level elevation that is higher than the coastline. Sea level rise and land subsidence are several factors that can cause the phenomenon of tidal flood. This study aims to predict the effect of the trend of sea level rise based on tidal data of 18.6 years and land subsidence on the level of tidal flood threat along the Bandar Lampung coastal area. Tidal data obtained from numerical model predictions are used to determine water level elevation and spatial approach using Geographic Information Systems (GIS) with Landsat-8 satellite image data processed to get the area of tidal flood inundation caused by sea level rise. The result indicates that the trend of sea level rise along the Bandar Lampung coastal area was 0.024 mm/year. The outcome shows that tidal inundation of short-term in 2027 is about 25.337 ha along the Bandar Lampung coastal area and for the long-term prediction in 2072 is 122.8 ha. From this result, the threat levels from 2022, short-term, and long-term predictions are predominantly in the low-threat level, but the inundation area increases every year.
