Management of coastal flood impact in rural area (Case study in Sayung District)

Abstract

Sayung Subdistrict, Demak Regency is a low-lying coastal area prone to coastal flooding. This coastal area's flood susceptibility is not influenced by a single factor, but by the combined effect of excessive rainfall, the morphological characteristics of coastal areas, and tidal waves. As a reason, the objectives of this study were to (1) map coastal flood-prone areas using a combination of heavy rainfall and tidal waves; (2) determined the extent of inundation; and (3) provide feedback on potential flood-affected area management. The findings indicate inundation has increased by 2.4% per year. Therefore, the evaluation of the mitigation management has to be considered either on local communities' perspective, regional and national government planning and non-government implementation. Local communities, with or without the assistance of NGO and regional governments, adapt their mitigation strategies to the changing environment, whether through physical, economical, or social approaches. Meanwhile, the regional and national governments' management will be incorporated into the detailed spatial planning.
