巽他大陆架位于东南亚，形成亚洲大陆大陆架的一个巨大的水下延伸。巽他大陆架包括婆罗洲、爪哇和苏门答腊的大巽他群岛，大陆架的大部分形成了南中国海的浅海底，柬埔寨、马来西亚半岛、新加坡、婆罗洲的沿海地区，以及印度尼西亚、泰国和越南的部分海岸。这一大陆架的特点是海岸线和海底地形复杂，这可能导致复杂的潮汐特征。在这项工作中，我们的目标是获得深刻的了解机制的潮波在这一地区的传播。为了实现这一目标，我们对泰国湾和附近地区进行了高保真模拟。高保真度包括高分辨率测深（30秒），更精细的比例尺捕捉和保护现实，复杂的海岸线和岛屿的能力。为此，我们采用有限体积法在我们的模拟，其几何灵活性，计算效率以及体积和质量守恒的保证。在目前的研究中，我们主要集中在巽他陆架区的潮汐动力过程中，我们数值仔细研究精确的无潮系统，以及相应的能量通量的主要潮汐（M2，K1，S2和O1）在中国南海的巽他陆架。与其他数值和实验观测结果进行了比较
The Sunda Shelf is settled in Southeast Asia where it forms a large submerged extension of the continental shelf of mainland Asia. The Sunda shelf includes the Greater Sunda Islands of Borneo, Java and Sumatra and the bulk of the shelf forms the shallow seabed of the South China Sea, the coastal areas of Cambodia, Malaysia Peninsula, Singapore, Borneo, and parts of the coast of Indonesia, Thailand, and Vietnam. This shelf is characterized by complex shoreline and seafloor topography which can result in complicated tidal characteristics. In this work, we aim to gain insightful understanding of mechanism of the tidal wave propagation in this region. To achieve this, we perform simulation with high fidelity for the Gulf of Thailand and nearby areas. The high fidelity includes high resolution bathymetry (30 seconds), finer scale capturing and ability to preserve the realistic, complex coastline and islands. To this end, we employ the finite volume method in our simulation for its geometric flexibility, computational efficiency as well as volume and mass conservation assurance. In the current study, we focus mainly on the tidal dynamic processes in the Sunda shelf region, and we numerically scrutinize exact amphidromic systems as well as the corresponding energy flux of the principal tides (M2, K1, S2 and O1) in the Sunda shelf of the South China Sea. Comparisons to other numerical and experimental observations have been done
