Test types

Several erosion tests have been done during the Polder2C's project, such as water overflow, wave overtopping and wave impact tests. Both Dutch and Belgian levees have been included in the research with varying types of levee cover, anomalies on the levee or water velocity.

Programming Tool

What: This is a Python programming tool for modelling overtopping (OTE2C). The aim is to reuse one of the existing available codes to introduce new parameters and erosion process description due to overtopping erosion. Our new code considers overtopping due to sea waves, since it is related to most likely overtopping conditions (high waves, tides effect in sea level rise process). The final objective is that the tool can also be used for overtopping due to wind waves of a dam reservoir or on river dikes, and to be runed with many different loading conditions to provide statistical analysis on risk of failure assessment.

Validated model on Erosion Progression

What: A report on the model validation on hydrodynamics and erosion resistance. It discusses modelling erosion progression for steady overflow and wave overtopping conditions.  

Overflow modelling

What: a report on overflow modelling, titled Hydrodynamics modelling under continuous levee overflow conditions

Steady Overflow and Wave Overtopping

What: a report with an integration of insights from our overflow and overtopping tests with regard to the hydraulics, how the water flows off, and its measurement, and in more detail the damage development.

Levee strength during erosion tests

What: an infosheet Vegetated levee strength during overflow and overtopping tests. The infosheet is based on these erosion tests and other field activities in the Living Lab Hedwige-Prosperpolder, and concerns the impact of surface anomalies on levee erodibility and stability. 

Insights from Overflow Experiments

What: an infosheet Overflow from river along the landward slide levee slope. This infosheet is based on overflow tests in the Living Lab Hedwige-Prosperpolder and sets out the main insights from these in situ experiments. 

Tidal marsh

What: an infosheet Tidal marsh stability under high flow velocities. This infosheet is based on both in situ experiments, overflow tests in the Living Lab Hedwige-Prosperpolder and laboratory experiments. The infosheet explains the main take aways from these experiments.
