Abstract

An Improve Performance of Geospatial Model to Access the Tidal Flood Impact on Land Use by Evaluating Sea Level Rise and Land Subsidence Parameters

Highlights

  • Climate change is the most important threat to humans in the twenty-first century (Toan, 2014)

  • In order to reduce tidal flooding, sea dikes and safety buildings were built on the North Coast of Java Island, including the coast of Pekalongan Regency (Bappenas, 2019), so the question to be answered from this research was “How wide the distribution of the tidal flood inundation area on coastal land use in Indonesia?”

  • This study aimed to examine the area oftidal inundation on land use based on inundation height, rate of sea level rise, land level elevation and land subsidence

Summary

Introduction

Climate change is the most important threat to humans in the twenty-first century (Toan, 2014). This extreme event causes an increase in temperature which leads to an acceleration of sea level rise (Seenath et al, 2016). Tidal flooding is a disaster that often occurs in cities or coastal areas, such as in Pekalongan Regency (Ramadhan et al, 2019). Pekalongan Regency is an area affected by tidal flooding due to the direct impact of climate change (Sauda et al, 2019). By using the geospatial method, paying attention to land subsidence and sea level rise will produce a prediction map of the inundation that will occur and its impact on land use in Pekalongan Regency. The problem to be solved in this study was to find the area and distribution of tidal inundation areas on coastal land use using a spatial modeling approach
