abstract

  • In recent years, heavy rainfall that exceeds flood control targets has been increasing, and the resulting flood disasters have become a serious problem. Flood control measures in urban areas require effective use of information from existing flood control facilities and observation records, and flood prediction models play an important role. To achieve this, it is extremely important to obtain rainfall observation information and in-pipe water level measurement information to effectively operate flood control facilities such as pumping stations. Utilizing flood records from various heavy rains and in-pipe observation data improves the urban flood model to a highly reproducible one. In Japan, where urban areas spread across coastal lowlands, river floods, drainage capacity, coastal storm surges, and tsunamis have complex effects on urban flooding, and models that can appropriately evaluate these are required. In this chapter, we apply a model that seamlessly combines river channels, sewerage network systems, surface floods, and coastal hydraulics to the low-lying urban area in the Tsurumi River watershed, where comprehensive flood control measures are being implemented. This chapter describes an advanced flood control approach that spatially and temporally integrates stormwater management facilities, and high-precision radar rainfall data, as well as a data assimilation approach that leverages in-pipe water levels for rapid and accurate prediction of urban flooding, and a surface water discharge approach to adequately reproduce surface drainage conditions when modeling simplified sewer networks. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2024.
