Den Bieman, J. (author), Van den Koppel, M. (author), Van Velzen, G. (author), Verbruggen, W. (author)One of the branches of the Paraná delta is the Paraná de las Palmas River. This branch doesn’t have the biggest discharge but has the most navigation. The situation in the Paraná de las Palmas isn’t without problems though; the river banks show erosion over the whole length of the branch. This erosion has been investigated by the following...student report 2010

Bijlsma, E. (author)In this manual design rules and guidelines for the design of Polyurethane Bonded Aggregate revetments (PBA-revetments) are presented, based on results from laboratory research, full scale model tests, and experience and field measurements. Research is still ongoing, but from the first results some insight into the structural behaviour of PBA can...report 2010

On behalf of, and in cooperation with the TU Delft and the MARD-CWRCT two dike designs are made for a pilot project on Cat Hai Island. Two different types of revetments are used, namely the Dutch block type revetment Basalton and the classic rip-rap revetment. The designs are based on the available boundary conditions, the...student report 2010

Caljouw, M. (author)Traditioneel worden dijken bekleedt met steenzettingen, asfalt, gras of breuksteen. Echter, er worden steeds meer initiatieven voorgesteld waarbij innovatieve materialen worden toegepast als dijkbekleding. Deze initiatieven zul len in de toekomst leiden tot een efficienter of maatschappelijk beter geaccepteerde dijkbekleding. Tot nag toe is voor...report 2010

(author)Elastomeric bonded permeable revetments, also called PBA (Polyurethane bonded aggregate) revetments, are highly porous structures made of mineral aggregates (e.g. crushed stones) which are durably and elastically bonded by polyurethane (PU). Despite their numerous advantages as compared to conventional revetments and the large experience...conference paper 2010

't Hart, R. (author)Uit de praktijk is een enkel geval bekend waarin de toestand van de teenconstructie zodanig is verwaarloosd dat van enige opsluiting eigenlijk geen sprake meer is. Het is dus reëel om te veronderstellen dat in praktijkgevallen de klemming kan worden gelimiteerd door bezwijken van de teenconstructie. Bij afschuiving kan onderscheidt worden...report 2010

Sluijsmans, R.W. (author)The elastocoast system can be used as an armour layer on revetments. The bonding system exists of a mix of crushed stones and 2-component polyurethane. This bonding system creates bonding forces between the stones and an open (porous) structure can be obtained. Elastocoast is developed by Elastogran GmbH, a BASF subsidiary. The response of an...master thesis 2009
