摘要

填海是在沿海地区或海洋中央建立新的陆地区域的努力。在Pamurbaya地区,许多住房和公寓的房地产项目仍在继续。海岸填海工程对环境的影响是潜在的水浸增加。这些变化包括集群的范围、河流沉积物的组成、潮汐模式、沿海洋流模式以及对水系的破坏。本研究考察了利用Delft3D软件模拟的填海所造成的当前模式、形态和沉积速率的变化。填海后的水流格局发生了变化。各断面填海前后的基本地表变化差异为:断面1 = +0.22 m,断面2 = -0.19 m,断面3 = +0.11 m。符号(+)表示沉积的发生,符号(-)表示侵蚀。断面1填海后为淤积,断面2为侵蚀,断面3为淤积。强度差异很小,因此填海后发生的侵蚀和沉积不太显著。

Impact of Reclamation Development on Sedimentation and Current Pattern in East Coast Surabaya (Pamurbaya)
Reclamation is an effort to establish a new land area either in coastal areas or in the middle of the ocean. In Pamurbaya area a number of property projects both housing and apartments is still continuing. Environmental impacts of the coastal reclamation project is in the potential increase of 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 study examines changes in current patterns, morphology, and sedimentation rate due to the reclamation modeled using Delft3D software. The pattern of current flow 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 the occurrence of sedimentation, while (-) is erosion. The condition after the reclamation in crossection 1 is sedimentation, crossection 2 is erosion, and crossection 3 is sedimentation. The difference in intensity is very small, therefore the erosion and sedimentation which took place after reclamation is not too significant.
