| Abstract (English): |
The Lamong Watershed (DAS Lamong), located in East Java, is vulnerable to flood hazards caused by rising sea levels and high rainfall intensity. This study centers on evaluating the risk of compound flooding in the lower area of the Lamong River Basin, where the coastal region, known as a low-lying area, is particularly prone to inundation. Flood simulation in this research relies on frequency analysis, where the design flood flow is determined using a synthetic unit hydrograph method, while rainfall-induced flood modeling utilizes rainfall intensity derived from rainfall frequency analysis. Tidal data is used to model the influence of coastal wave activity. This study employs the SFINCS model (SuperFast INundation of CoastS), which is capable of simulating river floods, rainfall-induced floods, and coastal floods simultaneously (compound flooding). Several structural mitigation strategies, including river normalization, construction of embankments, and sea walls, are also analyzed for their effectiveness in reducing flood risk. This study supports flood risk management in the Lamong River Basin and contributes to strengthening climate change adaptation and mitigation strategies for vulnerable riverine and coastal regions in Indonesia.

| Abstract (Indonesian): |
Daerah Aliran Sungai (DAS) Lamong yang berada pada Jawa Timur memiliki potensi terhadap bahaya banjir yang disebabkan oleh kenaikan permukaan air laut serta tingginya volume presipitasi. Penelitian ini dilakukan dengan maksud untuk mengetahui risiko banjir gabungan atau compound flooding pada wiliyah hilir DAS Lamong, yang diketahui bahwa wilayah pesisir merupakan daerah dataran rendah dan memiliki potensi terhadap genangan. Pemodelan banjir pada studi ini didasarkan pada analisis frekuensi dengan menghitung Debit banjir rancangan dianalisis menggunakan pendekatan hidrograf satuan sintesis, sedangkan simulasi banjir akibat curah hujan memanfaatkan intensitas hujan hasil analisis frekuensi. Adapun untuk memodelkan gelombang laut digunakan data pasang surut. Pemodelan studi ini menggunakan model SFINCS (SuperFast INundation of CoastS) serta dapat membantu untuk memodelkan genangan yang disebabkan oleh sungai, hujan, ataupun genangan yang disebabkan gelombang laut sekaligus (compound flooding). Berbagai upaya mitigasi struktural dilakukan, seperti normalisasi sungai, pembangunan tanggul, serta tanggul laut, turut dianalisis guna mengurangi risiko banjir yang ditimbulkan. Studi ini memberikan dukungan bagi pengelolaan risiko banjir pada DAS Lamong serta berperan dalam penguat strategi dan mitigasi dari dampak perubahan iklim di wilayah sungai dan pesisir yang rentan di Indonesia.
