ABSTRACT:  The UrbanFlood project is creating an Early Warning System framework that can be used to link sensors via the Internet to predictive models and emergency warning systems. The project includes four pilot sites to apply and validate at full scale the technology being developed in the project: Amsterdam (Netherlands), Boston (UK) and Rhine River (Germany). This paper focuses on a description of the sensor instrumentation installed at the pilot sites and the emerging conclusions from the analysis of the results obtained to date. The sensors installed at the various sites include various MEMS modules to measure displacement and pore pressure and fibre optic cables able to detect strains. The gathered data are used for dike stability evaluation with different models and also, combined with an Artificial Intelligence (AI) component, for detection of anomalies in dike behaviour. Detected anomalies trigger assessment of the likelihood of levee breach and the consequences in terms of flood propagation and damage in the defended urban area.

ABSTRACT:  Levees provide safety against floods worldwide. This paper presents a system to examine

levee strength continuous in space and time. Goal of the research is implementing a system for reliably predicting embankment strength during high intensity periods, enabling more effective safety measures. The research is part of the Flood Control 2015 program. The module REAL® developed by Fugro uses a 3D subsoil model and LIDAR height data to make safety assessments for different failure mechanisms. The module FEWS-DAM is developed by Deltares, it is a tool for automated assessment and design of levee. REAL® results for a 48 km dike ring situated in the east of The Netherlands were implemented in FEWS. In FEWS the Water Board can asses levee strength continuously in space and time for the whole study area, enabling better decision- and policy making. The pilot shows that implementation of both module is possible and valuable. For the full paper in PDF download here

ABSTRACT:  We present a data-driven modelling approach for detection of anomalies in flood defences (levees, dykes, dams, embankments) equipped with sensors. An auto-regressive linear model and feed-forward neural network were applied for modelling a transfer function between the sensors. This approach has been validated on a dike in Boston, UK -one of the pilot sites of the UrbanFlood project- that showed both normal and abnormal sensor behaviour. Comparison of the linear and non-linear models is presented. The suggested model-based anomaly detection approach will extend functionality of the developed Artificial Intelligence component of the UrbanFlood Early Warning System.

ABSTRACT:  Several  pilot  programs  have  been  carried  out  in  the  region  of Western Sacramento, California USA and The Netherlands to evaluate the state of the levees. Utilizing a methodology of automatic assessment based on defined criteria, a proprietary process called Rapid Engineering Assessment of Levees® was employed. It was selected because it offers significant advantages in flexibility and efficiency over conventional methods. The REAL® method incorporates levee geotechnical, geospatial and geological characteristics in its assessment and allows for systematic, consistent and repeatable evaluation at very closely spaced cross-section intervals and various water levels, 100 times faster than conventional work flows. This paper will discuss the results of pilot programs included lessons learned and future developments, including some new developments implemented and tested in The Netherlands.
