Sedimentation modeling for development of Kenjeran-Surabaya

Abstract

Surabaya City administratively has a maritime boundary consisting of 11 districts known as Pantai Timur Surabaya (Pamurbaya). One of them is Kenjeran area. The area located in the Development Unit 3 in the Urban Spatial Plan (RTRW) used as a Service and Trade Area and also used as a Tourism Area. Therefore, this study is important to know the shoreline changes and made recommendations in zone management development. Results of this study found that the area of Kenjeran dominated by sedimentation with sedimentation range 0.002-0.015 meters. The largest sedimentation is 2.36x106 m2 with sedimentation of 0.02 meters. Development of the area in Kenjeran is suitable with the RTRW Surabaya, but due to the large sedimentation, there are some things that must be considered such as the uncertainty of land ownership arise in Kenjeran and ecosystem damage. The solution offered is that the government should restrict the use of arising land and there should be clarification of rules from the government on arising land.
