Woods versus waves

The safe choice is the natural choice

Trees clean the air we breathe, hold the soil under our feet, shelter us from the sun and protect us against winds and floods. But what exactly is their protective power against floods under extreme conditions such as typhoons and tsunamis? We (a hydraulic engineer, a coastal ecologist and a coastal management expert) want to go where no researcher has gone before and test real trees with extreme waves in the massive Delta Flume. We invite you to take part in this ground-breaking research, in which we will address the most urgent knowledge gaps on the role of trees in flood risk reduction. Do floodplain forests in our rivers limit overtopping of levees and embankments? Did the presence of mangroves protect coastal communities during the Asian tsunami? These aspects can yet only be modelled, estimated and predicted to a limited degree, since measurements under extreme conditions and in a controlled environment, are not available. This research will unravel whether the protective power of trees is fact or fiction.

Our lobbying activities in the last two years resulted in research budget of 700.000 euro’s, but we are still 50.000 euro’s short. For that we seek your help.  Help us prove that woods are natural wave breakers.

An exclusive lecture on Nature Based Flood Defences


Nature-based flood defences are a relatively new approach to flood risk reduction and climate change adaptation. In this lecture you will learn why this research is essential to make large-scale and successful implementation possible.

Delta Flume experience


Witnessing a ‘woods versus waves’ test in the Delta Flume.

The Delta flume is 300 metres long, 9.5 metres deep and 5 metres wide. The depth makes it possible to generate waves up to 4.5 metres high. Waves this big cannot be generated anywhere else in the world. 


(Note: test dates are not flexible and you will be informed 2 days ahead).

Woods versus Tsunami experience


After an inspiring lecture by the scientists involved, you will be witnessing the ultimate wave in the Delta Flume. Will the trees be able to stop these massive high waves?
