Placement of Smart Grass reinforcement at test sections Groningen Sea dike

The present report deals with the application of a provisional Smart Grass Reinforcement (SGR) system in 2006 for full scale testing of increased overtopping at the Groningen sea dyke test section near Delfzijl, as envisaged in 2007. The SGR has been placed at two strips of 4 m wide: one primary strip at the basic test site and one at a...

Golfoverslag en sterkte binnentalud bij dijken

Dit verslag is een rapportage van ons afstudeerproject voor de opleiding algemene Civiele Techniek aan de Noordelijke Hogeschool Leeuwarden.Dit afstudeerproject is in samenwerking met INFRAM uitgevoerd. Het onderzoek richt zich op de sterkte van grasbekleding op het binnentalud van zeedijken. Voor het beproeven van de grasmat op locatie wordt...

Conceptual model for reinforced grass on inner dike slopes

A desk study has been carried out in order to develop a conceptual model for the erosion of inner dike slopes with reinforced grass cover. Based on the results the following can be concluded: The presence of a geosynthetic in a grass slope can be taken into account in the EPM method by increasing the critical flow velocity. In particular, a...

Vegetation dynamics and erosion resistance of sea dyke grassland

The high erosion resistance of grass swards on c1ay dykes seems to be largely determined by the amount of roots and the root system architecture. Following on previous studies on river dykes which revealed high root densities and erosion resistance in unfertilised pastures and hay-meadows, we experimentally investigated the influence of...

Technical report erosion resistance of grassland as dike covering

Old dikes are usually still constructed entirely from clay and since 1953 many much heavier dikes have been made from a core of sand with a covering. This construction puts heavier requirements on the covering, as it also does for grassland on a clay layer. These and other developments have led to the need for more insight into the strength of...
