Abstract

An inland waterway will be constructed in an existing channel in West Java, Indonesia. The change of salinity in a river due to capital dredging is investigated using a finite element modeling system. The location of the research is the Cikarang Bekasi Laut (CBL) channel, Bekasi Regency, West Java, Indonesia. The aim of this study is to simulate salinity propagation in the CBL before and after capital dredging. Salinity modeling is carried out using the Surface-water Modeling System (SMS). Field surveys of the topography, bathymetry, currents and water level are conducted for the model. The model results are validated with the current and water level field measurements. The field and model results agree well. The current and salinity results show that the trends are correlated with river discharges. After the capital dredging, the salinity in the CBL increases. Mitigation is carried out by constructing a check dam, which can reduce the average salinity in the upstream region by up to 0.05 ppt during the wet season and up to 0.12 ppt during the dry season.

印度尼西亚西爪哇省贝卡西县Cikarang Bekasi Laut海峡盐度传播模型

将在印度尼西亚西爪哇的一条现有航道上修建一条内河航道。利用有限元建模系统研究了疏浚引起的河流盐度变化。研究地点位于印度尼西亚西爪哇省贝卡西县的Cikarang Bekasi Laut（CBL）通道。本研究的目的是模拟基建疏浚前后CBL中的盐度传播。盐度建模是使用地表水建模系统（SMS）进行的。对该模型进行了地形、水深、洋流和水位的实地调查。模型结果通过电流场和水位场测量进行了验证。现场和模型结果一致。水流和盐度结果表明，趋势与河流流量相关。资本疏浚后，CBL中的盐度增加。缓解措施是通过建造一座拦水坝来实现的，这可以在雨季将上游地区的平均盐度降低0.05 ppt，在旱季将其降低0.12 ppt。
