RESEARCH ON CONSTRUCTION OF SEA LEVEL RISE DATABASE TO SUPPORT LAND USE MANAGEMENT IN COASTAL AREAS OF THANH HOA PROVINCE

Abstract

Climate change and sea level rise pose serious challenges to coastal areas, especially in provinces with high population density and intensive economic activities such as Thanh Hoa province. In this context, the development of a sea level rise database is an essential foundation to support proactive and sustainable land management and planning. This study focuses on building a database of inundation risk caused by sea level rise for the coastal zone of Thanh Hoa province, based on DEM data, remote sensing and RCP climate scenarios. Land use data from the ESRI 10 m Land Cover dataset were integrated to analyze the degree of impact on each land use type at the time milestones of 2050, 2080, 2100. The results indicate that flood risk increases significantly over time and across emission scenarios, particularly affecting agricultural land, built-up areas and coastal forest zones. The generated inundation risk maps and quantitative statistics provide a scientific basis to support decision-making in land resource management and spatial planning in response to climate change.
