Due to environmental protection efforts, there is a growing number of beavers in the Netherlands. As these animals make their burrows in the levee system they cause damage within it, increasing the risk of flooding. This paper assesses the factors which increase the risk of beaver activity within the …

Report on testing of water overflow on Dutch levees. On the Dutch part of the levee in Hedwige-Prosperpolder, 11 overflow tests have been conducted. Overflow tests on levees are designed to test the strength of levees and levee covers under the load of a continuously overflowing discharge of water. …

This report bundles the annexes for the data report of the overflow tests executed on the Belgian part of the Hedwige-Propserpolder levees. Overflow tests on levees are designed to test the strength of levees and levee covers under the load of a continuously overflowing discharge of water. For this …

Report on testing of water overflow on Belgian levees. On the Belgian part of the levee at the Prosperpolder, 14 overflow tests have been conducted on 12 sections. Continuous overflow tests on levees are designed and executed to test the strength of levees and levee covers under the load of a continuously …

Engineers design levees without taking into account animal activity. But in reality: *Levees attract burrowing animals *Many of them are protected (e.g. beavers) *It is not always easy to detect burrows and remove them Topics of interest are: 1. Eco engineering approaches for deterrence of animals …

Poster. Polder2C’s is an Interreg-funded project that aims at flood resilience building through fieldwork in the Living Lab Hedwige-Prosperpolder (LLHPP). LLHPP consisted of a 3 Km-long levee where various large-scale surveys, superstorm simulations and emergency response exercises took place in the …

Animal burrows create discontinuities on the body of earthen levees that under certain circumstances can threaten their structural integrity through hydraulic alteration and surface erosion. Although it is a virtually established fact that discontinuities can undermine the structural integrity of levees, …

Infosheet. When high water is expected, levee managers need to make sure that there are no weak spots on the levee that can compromise its structural integrity. Animal burrows on a section can constitute weak spots that have to be urgently repaired in anticipation of high water. Within the context of …

Infosheet. Within the context of animal burrows surveys that took place in the test season 2021-2022 in the living lab Hedwige-Prosperpolder, an experimental setup with smoke bombs was developed to verify whether detected burrows by small rodents are interconnected in the subsurface. By injecting colored …

Er is wereldwijd een groeiende groep milieuvluchtelingen. Voor deze mensen, die vluchten als gevolg van bijvoorbeeld een tsunami, dijkdoorbraak, hoge concentraties vrijkomende giftige stoffen bij een industrieel ongeval, verwoestijning, uitputting van de bodem of langdurige regenval, bestaat nog geen …
