Experience of using FEM for real-time flood early warning systems: Monitoring and modeling Boston levee instability

摘要

Boston levee has a documented history of slope slippages under tidal fluctuations reaching 6-m range on spring tides. A finite element model of the Boston levee has been developed in the off-line mode; after that, it was integrated into the common information space of the UrbanFlood early warning system and connected to live sensor data stream registering tidal fluctuations of river level and corresponding response of pore pressures and media temperatures. Stability analysis was carried in a real-time mode.
