RESEARCH SURVEY ON POLLUTANT AND SEDIMENT PROCESSES IN RIVER-COAST SYSTEMS IN INDONESIA

目标：本研究项目旨在明确印度尼西亚促进沿海社区可持续社会进步的必要发展。对爪哇海的污染物、河流流量、泥沙输移、水循环进行了研究，建立了河岸系统水循环和物质输运的模拟方法。本研究的主要成果如下：1.向海洋的扩散过程：研究了亚洲季风、ENSO、DM(偶极子模式)等大尺度气象事件对爪哇海洋流和风生流的影响，并对卡普阿斯河流域和本亚特湾的汞污染进行了调查。根据调查结果，可持续发展的基本理念…通过收集爪哇、苏门答腊岛、苏拉威西岛和加里曼丹群岛的河流主要排放物资料和NCAR/NCEP再分析资料，建立了利用天气再分析资料进行河流流量预报的方法。3.河口的沉积和扩散：研究了雅加达市垃圾的产生机理、河口垃圾的沉积、4.雅加达市区：收集和整理雅加达市区泥沙和废物资料。5.索洛河流域：索洛河流域泥沙综合管理。6.云南省盘当市地区：NCAR/NCEP资料估算的河流流量、大坝泥沙淤积和河口三角洲形成之间的关系，7.爪哇海近岸海域：利用本研究开发的风驱动环流模式对爪哇海的物质输送进行了模拟，建立了物质扩散预测方法。8.调查结果的综合：最后，对调查结果进行了总结和综合，以找出印度尼西亚未来必要的发展方向。较少

Objectives : This research project aims to make clear the necessary developments in Indonesia to promote sustainable social progresses in the coastal community. Investigations of pollutant, river discharge, sediment transport, water circulation in the Java Sea are conducted together with establishing the simulation method for water circulation and material transport in the river-coast system. Collected information and developed simulation technique will be complied to establish the future Asia Environmental Simulator.Main Results : The results obtained by this research are as follows.1.Diffusion Processes to the Ocean : The effects of the large scale meteorological events, such as Asian monsoon, ENSO, DM (Dipole Mode), on the ocean currents and wind-driven currents in the Java Sea were investigated.Surveys of mercury pollution in Capuas river basin and Bunyat Bay, were conducted to make clear the level of contamination. Following the survey results a basic idea of sustainable developme … More nt was considered together with earth environmental preservation and the North-South problem.2.Generation and Transport Processes in the River : Data collections of the river major discharges in the Java, Sumatra, Sulawesi and Kalimantan Islands, and NCAR/NCEP reanalysis data were conducted to establish the method of river discharge prediction using weather reanalysis data.3.Deposition and Diffusion in the River Mouth : The followings were investigated, generation mechanism of waste in the city of Jakarta, waste deposition in the river mouth, its diffusion processes to the Java Sea.4.Jakarta City Area : Data of sediment and waste information in the Jakarta City Area were collected and filed.5.Watershed of Solo River : Integrated sediment management in the Solo river basin was discussed.6.Unjung Pandang City Area : Relation between river discharge estimated with NCAR/NCEP data, sediment deposition in dam, and river mouth delta formation, were investigated.7.Coastal Area of the Java Sea : Material transport in the Java Sea was simulated using the wind-driven circulation model developed in this study to establish the method of material diffusion prediction.8.Integration of Survey Results : Finally results of investigations were summarized and integrated to find the necessary future development in Indonesia.
