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，以预测河口和沿海沃茨的潮汐速度场和污染物输送率，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取得的学术成果是后，利用CAD系统将其加工成精美的图形，使CAD图形在河口、海岸沃茨的利用、管理和环境创造等新项目的决策中得到普遍应用。尽管日本的研究人员是工科专业，但他们大多数不仅对阐明物理机制感兴趣，而且对将其学术成果应用于管理工作感兴趣。以下课题已成为合作研究的主题。1.计算机显示软件在管理中的应用三维气压 关于我们 大坂大学发展了一种用于预测潮流、异重流和余流系统的线性流算法。数值结果可以通过高分辨率的计算机动画显示软件从布拉德福德大学转移。因此，可视化使人们能够更好地了解物理现象，特别是污染物输运过程和相关的余流系统.分层流ASM湍流模型的发展将大坂大学发展的高级湍流模型应用于布拉德福德大学的现场数据和实验室测量。对湍流参数的精细化进行了研究.热带红树林沼泽的水动力学;马来西亚Sains大学已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。对现有模型DIVAST进行了改进。特别强调的是集中在处理的小溪沼泽系统，曲流小溪和底部摩擦表示在沼泽。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
