Abstract
Reklamasi merupakan upaya pembentukan suatu kawasan daratan baru baik di wilayah pesisir pantai ataupun di tengah lautan. Di kawasan pamurbaya saat ini masih terus berlanjut sejumlah proyek property baik perumahan maupun apartemen. Dampak lingkungan dari proyek reklamasi pantai adalah meningkatkan potensi banjir Perubahan itu antara lain berupa tingkat kelandaian, komposisi sedimen sungai, pola pasang surut, pola arus laut sepanjang pantai dan merusak kawasan tata air. Tugas akhir ini meneliti tentang perubahan pola arus, morfologi, serta laju sedimentasi akibat Reklamasi yang dimodelkan menggunakan software DELFT3. Pola arus setelah adanya Reklamasi mengalami perubahan. Perubahan permukaan dasar yang terjadi sebelum dan setelah reklamasi di tiap crossection yaitu dengan selisih, crossection 1 = 0.22 m, crossection 2 = -0.19 m, dan crossection 3 = 0.11 m . Tanda (+) menunjukan di sedimentasi, dan (-) erosi. Keadaan setelah adanya reklamasi yang terjadi yaitu pada crossection 1 mengalami sedimentasi, crossection 2 mengalami erosi, dan crossection 3 mengalami sedimentasi, nilai selisih sangatlah kecil sehingga erosi dan sedimentasi yang terjadi setelah adanya reklamasi tidak terlalu signifikan.

Reclamation is an effort to establish a new land area either in coastal areas or in the middle of the ocean. In pamurbaya area is still continuing a number of property projects both housing and apartments. Environmental impacts of the coastal reclamation project is to increase the potential for flooding. The changes include the extent of the cluster, the composition of river sediments, the tidal pattern, the pattern of ocean currents along the coast and damaging the water system. This final project examines changes in current patterns, morphology, and Sedimentation rate due to the reclamation modeled using DELFT3 software. The current pattern after the reclamation has changed. Basic surface changes that occur before and after reclamation in each crossection is by difference, crossection 1 = 0.22 m, crossection 2 = -0.19 m, and crossection 3 = 0.11 m. The sign (+) shows in sedimentation, and (-) erosion. The condition after the reclamation that occurs in crossection 1 has sedimentation, crossection 2 has erosion, and crossection 3 has sedimentation, the value of difference is very small so that the erosion and sedimentation that happened after reclamation is not too significant.
