项目摘要
To achieve the various objectives such as flood damage prediction, flood mitigation, river basin development, a highly accurate numerical simulation model, consisting of inundation flow model and sewerage system model, for river water inundation as well as landside water inundation for urban area has been developed. In the inundation flow model, a new solution technique is employed that both river flood flow and river water inundation are solved simultaneously by the highly accurate numerical model for 2D unsteady free surface flows (SA-FUF-2DF model), and such new features as a dry/wet boundary condition for inland topography, a digital surface model (DSM), use of aerial photographic, and geographic information system (GIS) are incorporated as well in order to estimate flood discharge and to reproduce the complex behavior of the inundation flows with high accuracy as well as to achieve the stable calculation and easy data management. In the sewerage system model, the dynamic network model, based on FDS scheme combined with the Preissmann slot, is newly developed to simulate free耀urface and/or pressurized flow flows in a closed conduit, and is testified against experimental data.The model is calibrated against the landside water inundation in Iiduka city (2003) in the Onga river basin, which occurred due to inundation of branches and power deficiency of drainage pump stations. It is also demonstrated from numerical simulations under hypothetical storm intensity pattern in the Onga river basin that the model is a useful tool for achieving the above stated various objectives.
为了实现各种目标,例如洪水破坏预测,减轻洪水,河流开发,是一种高度准确的数值模拟模型,包括基础设施流量模型和污水处理系统模型,用于河水注入以及城市地区的地下水注入。在基础架构流量模型中,采用了一种新的解决方案技术,即仅通过高度准确的数值模型来解决河流洪水流量和河流注入,用于2D不稳定的自由表面流动(SA-FUF-2DF模型),以及作为内陆地面模型(DSM)和地理系统的内陆地面模型(DSM)的新功能(诸如干/潮湿的边界条件),并将其用于空气图,并将其用于Enapery System(DSM)。以高度准确性以及实现稳定的计算和易于数据管理的重现基础设施流动的复杂行为。在下水道系统模型中,基于FDS方案与Preissmann Slot相结合的动态网络模型是新开发的,是为了模拟封闭导管中的自由骨骼和/或加压流动流量,并根据实验数据进行了测试。该模型在Iiduka City(2003年)在河流基础上进行的蓄水式延伸(2003年)的供应量及时,该模型对河流的高度延迟进行了校准,该分支机构发生在河流中,该分支机构发生在河流中,该分支机构发生了,该分支机构发生在河流中,该河流及其在河流中的延迟,该河流及其在河水中的延迟,该河流及其在河流中的延伸范围,该河流及其在河流中的延伸及其供应,该河流及其供应量的延伸范围。从假设的风暴强度模式下,该模型是实现上述各种目标的有用工具,也可以从假设风暴强度模式下的数值模拟证明。
