Het grondgedachte voor het predictiespoor is geschreven volgens het KOLB-principe (www.thesis.nl/kolb). Dit houdt in dat eerst de mogelijke faalmechanismen worden beschreven op basis van bestaande kennis (wat neem je waar? - feeling). Dus een beschrijving van de huidige stand van zaken. Voor zover mogelijk worden dan de faalmechanismen zo goed...

A desk study has been carried out regarding interface stability of granular filter structures. Actually, the project focuses on two particular aspects: (1) interface stability as function of the thickness of the filter layer consisting of standard armourstone gradings, and (2) interface stability of gravel mixtures with a wide gradation The...

This document presents a set of Best Practice Guidelines for road development and rehabilitation in the Mekong floodplains of Cambodia and Viet Nam. The guidelines are developed under the ‘Roads and Floods’ project1. The guidelines are based on the review of local practice, international experience, and case study results. They are intended for...

Het onderzoeksprogramma Sterkte en Belastingen Waterkeringen (SBW) heeft als doel het invullen van de belangrijkste kennisleemtes voor een scherper beeld van de veiligheid van primaire waterkeringen tegen overstromingen. Een van de projecten is SBW-Reststerkte. De reststerkte is het waterkerend vermogen dat overblijft na initiële schade aan een...

Wave overtopping discharges at coastal structures are well described in the EurOtop Manual (2007), including the distribution of overtopping wave volumes. Each volume that overtops a dike or levee will have a certain flow velocity and depth record in time, often given by the maximum velocity and flow depth. This paper describes some further...

This paper discusses scour without bed protection, such as propeller scour, two-dimensional horizontal, three-dimensional horizontal scour generated by free jets downstream of gates and outlets, two-dimensional vertical and three-dimensional vertical scour. The flow velocities in two- and three-dimensional propeller and free jets are briefly...

Traditional guidelines on rock protection at circular piers predominantly focus on preventing shear failure (by choosing a sufficiently large rock size), winnowing failure (by designing an appropriate filter) and edge failure (by selecting a sufficient extent). In particular areas (e.g. in an eroding river channel or in an area with large-scale...

Granular filters are used for protection of structures against scour and erosion. For a proper functioning it is necessary that the interfaces between the filter structure, the subsoil and the water flowing above the filter structure are stable. Stability means that there is no transport of subsoil material through the filter to the water above...

Destructive wave overtopping tests have been performed at more than 20 dike sections in the Netherlands using the Wave Overtopping Simulator to simulate the overtopping waves. The tests show the combined behaviour of turf and substrate up to mean wave overtopping discharges of 75 ?/s per m, meaning wave volumes up to 5,500 ?/m with flow...

Dit rapport is voortgekomen uit de resultaten van een vier jaar durend destructief onderzoek naar de erosiebestendigheid van binnentaluds onder golfoverslagbelasting. Dit onderzoek is onder andere uitgevoerd met de golfoverslagsimulator. In het onderzoek is kennis ontwikkeld over de wijze waarop golfoverslag de grasbekleding van een binnentalud...

When a ship sails with a certain speed, there is always a return current along and under the ship. The return current induces a water level depression around the ship. When the ship travels along a bank, the flow field around the ship is asymmetrical. Additional bank effects will be induced. A reliable estimation of all these effects and the...

Granular filters are used for protection against scour and erosion of base material. For a proper functioning it is necessary that at the interfaces between the filter structure, the subsoil and the water flowing above the filter structure no material will be transported. Different types of granular filters can be distinguished, this paper...
