“…The area is frequently affected by cyclonic storms and intense convectional precipitation occurring especially during the flood season (June to September). According to Quan (2014), pluvial flooding is accounted for more than half of the total flood events from 251 to 2000 in Shanghai, mostly in urban area.…”

Urban pluvial flood are attracting growing public concern due to rising intense precipitation and increasing consequences. Accurate risk assessment is critical to an efficient urban pluvial flood management, particularly in transportation sector. This paper describes an integrated methodology, which initially makes use of high resolution 2D inundation modeling and flood depth-dependent measure to evaluate the potential impact and risk of pluvial flash flood on road network in the city center of Shanghai, China. Intensity-Duration-Frequency relationships of Shanghai rainstorm and Chicago Design Storm are combined to generate ensemble rainfall scenarios. A hydrodynamic model (FloodMap-HydroInundation2D) is used to simulate overland flow and flood inundation for each scenario. Furthermore, road impact and risk assessment are respectively conducted by a new proposed algorithm and proxy. Results suggest that the flood response is a function of spatio-temporal distribution of precipitation and local characteristics (i.e. drainage and topography), and pluvial flash flood is found to lead to proportionate but nonlinear impact on intra-urban road inundation risk. The approach tested here would provide more detailed flood information for smart management of urban street network and may be applied to other big cities where road flood risk is evolving in the context of climate change and urbanization.

“…It reveals floods' monthly distribution pattern. Previous studies empirically proposed the five months May-September as the flood-prone season [38,44,54] Several factors can influence flood frequency, e.g., variation in precipitation and typhoon, sea level rise, land subsidence, urbanization, upstream floods, and flood management [38][39][40]55]. The different trends of monthly floods are likely due to inter-annual and inter-month variations of precipitation and typhoons.…”

“…Regional flood frequency analysis may provide important tools for such studies [57]. Although the influencing factors vary from one flood subtype to another [39,40,54,58], an important reason for these different changes probably lies in flood management.…”

Abstract:A valuable aid to assessing and managing flood risk lies in a reliable database of historical floods. In this study, a newspaper-based flood database for Shanghai (NFDS) for the period 1949-2009 was developed through a systematic scanning of newspapers. After calibration and validation of the database, Mann-Kendall tests and correlation analysis were applied to detect possible changes in flood frequencies. The analysis was carried out for three different flood types: overbank flood, agricultural waterlogging, and urban waterlogging. The compiled NFDS registered 146 floods and 92% of them occurred in the flood-prone season from June to September. The statistical analyses showed that both the annual flood and the floods in June-August increased significantly. Urban waterlogging showed a very strong increasing trend, probably because of insufficient capacity of urban drainage system and impacts of rapid urbanization. By contrast, the decrease in overbank flooding and the slight increase in agricultural waterlogging were likely because of the construction of river levees and seawalls and the upgrade of agricultural drainage systems, respectively. This OPEN ACCESSWater 2015, 7 1809 study demonstrated the usefulness of local newspapers in building a historical flood database and in assessing flood characterization.

“…dunes, groynes or seawalls) (Bates et al, 2005). However, pumping stations play a crucial role in defending against fluvial floods (Quan, 2014). This type of flooding is caused by inundation from river flows and can occur either due to intense, high velocity flash floods or excessive rainfall that causes river channels to overflow their banks (Fernandez et al, 2015).…”
