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

目的：本研究项目旨在明确印尼的必要发展，以促进沿海社区的可持续社会进步。对爪哇海进行了污染物、河流排放、输沙、水循环的调查，建立了河滨水系水循环和物质输运的模拟方法。收集到的资料和开发的模拟技术将用于建立未来的亚洲环境模拟器。主要结果：本研究得到的结果如下：1。向海洋扩散的过程：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动流的影响。对卡普阿斯河流域和班亚特湾的汞污染进行了调查，以明确污染程度。根据调查结果，可持续发展的基本思想是……更多的是考虑到地球环境保护和南北问题。2 .河流的产生和输送过程：利用爪哇、苏门答腊、苏拉威西和加里曼丹群岛的河流主要流量数据和NCAR/NCEP再分析数据，建立了利用天气再分析数据进行河流流量预测的方法。3 .研究了雅加达市废弃物的产生机理、废弃物在河口的沉积及其向爪哇海的扩散过程。雅加达市区：收集并归档了雅加达市区沉积物和废物信息的数据。索罗河流域：讨论了索罗河流域泥沙综合治理。7.云中潘塘城区：研究了NCAR/NCEP数据估算的河流流量、大坝泥沙淤积和河口三角洲形成之间的关系。7 .爪哇海沿岸地区：利用本研究建立的风驱动环流模式模拟爪哇海的物质输送，建立物质扩散预测方法。调查结果的整合：最后对调查结果进行总结和整合，以找到印尼未来发展的必要条件。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.
