Open WL Archief (OWA)

Over het archief

Het OWA, het open archief van het Waterbouwkundig Laboratorium heeft tot doel alle vrij toegankelijke onderzoeksresultaten van dit instituut in digitale vorm aan te bieden. Op die manier wil het de zichtbaarheid, verspreiding en gebruik van deze onderzoeksresultaten, alsook de wetenschappelijke communicatie maximaal bevorderen.

Dit archief wordt uitgebouwd en beheerd volgens de principes van de Open Access Movement, en het daaruit ontstane Open Archives Initiative.

Abstract

In 1995, the OMES-project (Onderzoek Milieu Effecten Sigmaplan) was started to study the impact of the SIGMA-plan on the ecosystem of the Scheldt-estuary. This project should result in an ecosystemmodel. It is known that reed (Phragmites australis (Cav.) Steud), which is a dominant species on the marshes of the Scheldt-estuary, influences the microbial processes in the soil and plays an important role in the nitrogen retention. It is able to withstand extreme environmental conditions such as extreme water regimes. An increase in the reedarea could play an important role in the ‘purification capacity’ of the Scheldt-estuary and thus lead to a decrease in the nitrogenload of the Northsea. Therefore it is necessary to know how reed reacts at different tidal situations. One of the objectives of the SIGMA-plan is the construction of ‘controlled inundation areas’ in which the hydrological characteristics will differ from those in the marshes. Yet, it is expected that in many of these ‘controlled inundation areas’, reed will be a dominant plant species. At the University of Antwerp, a mesocosm experiment will be carried out, in which different tidal regimes are simulated. Reed is planted at different levels and will be subjected to different flooding regimes. The growth and biomass of reed during the growing season will be measured. The aim of the poster is to explain the construction and creation of the tidal regimes.
