This document summarizes a presentation given by T. Peters of Deltares on developments in levee safety and the IJkdijk project. The presentation introduced Deltares and discussed flood protection in the Netherlands. It described the smart levee concept which combines sensor technology and levee engineering. The IJkdijk project was highlighted as a field test of new sensor technologies and knowledge of failure mechanisms. DAM software was presented as a tool for automated levee assessment, real-time failure forecasting, and improving levee lifecycle management. In conclusion, sensor technology, data integration, and early warning systems were discussed as keys to addressing new flood protection challenges from climate change.

Flood protection NL
Elevation of the Netherlands 13
Sea defences Sea Dike Large heights Long outer slope Extreme loading condition during storm at sea (several hours) Wave attack 14
River dikes/levees Long stretches With / without fore land Extreme loading condition during high river level (several days, time dependent flow) Development of pore pressure in and underneath dike Houses on and behind the dike 15
Canal dikes Small dimensions Water level almost constant Difference between daily and extreme conditions (relatively) small (stationary flow) Loading conditions during extreme rainfall or drought (peat) and external actions 16
Failure modes of levees Height is important, but…. 1953 Overflow Overtopping Other failure modes matter also. Slope stability inwards Slope stability outwards Seepage face erosion Piping/Heave (internal erosion) Liquefaction Revetment failure 17
IJkdijk research - smart levees FEWS-DAM floodrisk management
Smart levee concept . Combining dike & sensor technology for floodrisk management and real-time prognoses of dike stability . Use information also to optimize levee maintenance and levee improvement programmes IJkdijk
The IJkdijk project: full scale field research Double goal of the IJkdijk experiments: . Testing of new sensor and remote sensing technologies for Smart Levee concept . Increase knowledge on failure mechanisms History of tests: . . 2007 2008 project start-up, opening by Minister (wave overtopping test) Stability Test (6m high, 100m long levee) . . 2009 2012 Piping Tests (seepage erosion, 2x2 full-scale tests) All-in-one tests (seepage erosion, micro/macro stability, piping prevention measures) . 2012 Innovative piping (seepage) preventing techniques. IJkdijk
All in One - Sensor Validation Test 15 commercial companies and 4 research organisations from all around the world cooperating in this field test Goal: can measurements predict dike failure?
All in One - Sensor Validation Test – before
All in One - Sensor Validatie Test - after
DAM: Toolbox for automated levee assessments
Stochastic model of the subsoil
Result: automated levee assessment • Regular assessment by law in accordance with prescribed schematization by codes and standards • Platform allows fully automated assessment of a levee system
FEWS-DAM: real time forecasting of levee strength When clicking on a dot, a new window will pop up. This window displays the water height and probability of failure for the failure mechanism piping (see ) Color Range to display Color of dots depends on probability of failure calculated probability of failure. 27
Conclusion • Climate change  the Netherlands are facing major new challenges on flood protection • First key: New measurement technology in the dike (fibre optics, micronano sensors) and remote sensing (LIDAR, SAR, ….) providing real-time observations. • Second key: data-model integration. DAM already improves the cost effectiveness of the levee life cycle management for: • Maintenance and planning • Assessment (5-yearly checkup) • Reinforcement and design • Third key: DAM connected to Flood Early Warning Systems (FEWS) provides real-time prediction of failure as a decision support tool for floodrisk management.
And will this be the future of flood protection? Thank you for your attention
