摘要：迪拜2020年世博会预计将证明迪拜作为一个新兴阿拉伯城市的地位，通过标志性项目、一系列零散的城市飞地和工程景观展示其现代性。新的迪拜运河创造了一条航行路线，将历史中心与新兴的人工岛屿交织在一起。新运河突出了迪拜的城市形象，这是一个在技术先进的基础设施系统上发现的城市空间，提供了新的城市全景，提高了其步行能力，并沿河岸创造了公共空间。本论文研究了这些新的滨水开发项目所体现的城市变化和城市重心的转移。试图统一城市空间的功能，在同一个空间中生活、工作、移动和重建的尝试被分析为对现有的碎片化实践的一种背离。文中还讨论了历史形式和现代功能的再创造，以及迪拜试图通过使用属于不同文化的建筑元素来展示自己作为一个全球城市，以吸引不同种族的人。最后，为了评估运河中是否会出现停滞点，从而危及运河的功能和吸引力，利用二维水动力模型预测运河、弯道和泻湖中的流速和环流模式。

Abstract:Dubai’s 2020 Expo is expected to authenticate Dubai’s status as an emerging Arab city that displays modernity through iconic projects, sequences of fragmented urban enclaves, and engineered landscapes. The new Dubai Canal creates a navigational route that interlaces the historic centre with newly emerging artificial islands. The new Canal accentuates Dubai’s city image as an urban space found on technologically advanced infrastructural systems, and offers new panoramas of the city, enhancing its walkability, and creating public spaces along its banks. This current paper studies the urban changes and the city’s shift of focus manifest with these new waterfront developments. The attempt to unify the functions of the urban space, to live, work, move, and recreate in the same space is analysed as a departure from the fragmented practices existing until now. The recreation of historical forms and functions in a modern setup, and the attempt of Dubai to present itself as a global city through the use of architectural elements belonging to various cultures in order to appeal to different ethnicities are also discussed. Finally, in order to assess whether stagnation points would develop in the Canal which could jeopardize its function and appeal, a two-dimensional hydrodynamic model was utilized to predict the velocity and the circulation flow pattern in the canal, bends and lagoons.
