Numerical Modeling of Flow and Mass Transport in Estuary (With particular application to Mangrove Swamps)

两所大学合作的主要目的和目标是改进和进一步发展数值计算机模型，以预测河口和沿海水域的潮汐速度场和污染物运移速率，并具体应用于马来西亚的红树林沼泽。合作研究的原因是英国大学获得的学术成果通过CAD系统后处理为美丽的图片，因此CAD图片通常用于新项目的政治决策，用于河口和沿海水域的利用、管理和环境创造。大多数日本研究人员不仅对阐明物理机制感兴趣，还对将他们的学术成果应用于管理工作感兴趣，尽管他们的专业是工程。以下主题已成为合作研究的主题。计算机显示软件在管理中的应用三维Baroc…对于大阪大学的潮流、密度流和余流系统的预报，已经发展了更多的线性流算法。数值结果可以用布拉德福德大学的高分辨率动画计算机显示软件来可视化。因此，可视化使人们能够更好地了解物理现象，特别是污染物的输送过程和相关的余流系统。分层流动ASM湍流模型的发展大阪大学发展的一个更高的湍流模型被应用于布拉德福德大学的现场数据和实验室测量。对湍流参数进行了修正。热带红树林沼泽的水动力；马来西亚塞恩斯大学同意提供红树林沼泽和河口水流的实地数据。他们参加了我们在槟城的会议。对现有的DIVAST模型进行了改进。重点讨论了小溪-沼泽系统、曲流河和沼泽中的底部摩擦现象。较少

The main aims and objectives of the collaboration between both universities are the refinement and further development of numerical computer models to predict tidal velocity fields and pollutant transport rates in estuary and coastal waters, with specific application to mangrove swamps in Malaysia.The reason of the collaborative research is that the academic results obtained in UK universities are post-processed to beautiful pictures using the CAD system so that the CAD pictures are generally used in the political decision for new projects for utilization, management and environmental creation in estuary and coastal waters. Most of Japanese researchers take an interest not only in clarifying the physical mechanism, but also in applying of their academic results into the administration works, even though their specialties are engineering.The following subjects have become themes of collaborative research.1. Application of Computer Display Software for Management ;Three-dimensional baroc … More linic flow algorithms have developed for predicting the tidal flow, density flow and residual current system in Osaka University. The numerical results could be visualized by high resolution animation computer display software transferred from Bradford University. As a result, the visualization makes one to gain a better understanding of physical phenomena, especially the pollutant transport process and the related residual current system.2. Development of ASM turbulence model for stratified flows ;A higher turbulence model developed in Osaka University is applied to field data and laboratory measurements in Bradford University. Refinement of the turbulent parameters is examined.3. Hydrodynamic in Tropical Mangrove swamps ;The University Sains Malaysia has agreed to provide field data for flows in the mangrove swamps and estuaries. They joined our meeting in Penang. Refinement of an existing model DIVAST are applied. Particular emphasis is focused on the treatment of the creek-swamps system, the meandering creek and the bottom friction representation in the swamps. Less
