Suspended Solids and Sediments in the Scheldt Estuary –Environmental Impact of the SigamaplanThis project is under the framework of “Onderzoek Milieu Effecten van het Sigmaplan(OMES)”. OMES entails a multidisciplinary study of the environmental consequences ofhuman interference in the Scheldt Estuary (Belgium). More specifically attention is given toeffects of the Sigmaplan, dredging activities and harbour extension in the Zeeschelde, onhabitats and pollutions. The complete research project consists of eight (8) major aspectsrelating to the monthly monitoring of the physical, chemical and biological parameters ofthe pelagic, intertidal and subtidal areas as well as of the lateral load of the Zeescheldeand its tributaries. The obtained database aims to develop an ecological model and to putthe model into practice. This multidisciplinary research project is carried out by partnersfrom Universiteit Antwerpen, Vrije Universiteit Brussel, Universiteit Gent, Université Librede Bruxelles and Université Paul Sabatier Toulouse. Our research task mainly deals withthe physical and sedimentological study of the Scheldt Estuary including water flowcharacteristics, suspended solid concentrations and loads, the physical properties of thesuspended solid, as well as the sediment accumulation rates on marshes.M. Chen, S. Wartel, and F. De SmedtA Fundamental Study on Exchange Processes in RiverEcosystemsThis FWO (Fonds voor Wetenschappelijk Onderzoek- Vlaanderen) financed project whichstarted in 2004 and officially finished end of 2007. FWO granted the continuation of theproject until 2009. It is a fundamental research project, which is performed on amultidisciplinary basis and includes scientists from HYDR-VUB, Hydraulics Laboratory ofthe University of Ghent and the Department of Biology, Ecosystem Management ResearchGroup (ECOBE) of the University of Antwerp. The latter is promoter of the project. Themain aim of the research project is to investigate how the diverse physical and biologicalprocesses and their interactions determine the exchange of water, dissolved compoundsand particulate matter in margins and inundation areas of water courses. These twotransition systems are of high importance for the ecological functioning of river basins.The VUB-team investigates the interaction of the groundwater with the ecosystem, moreparticularly the exchange of water between the water course or inundation areas with thehyporheic zone. The introduction of innovative, but cost effective field investigationmethods as nested piezometers placed in the riverbed and equipped with data loggers,- 56 -
the ‘Temperature stick’ and seepage meters lead to a better perception of the diversephysical and biological processes and their temporal and spatial distribution on a localscale. Several of these processes like physical transport and chemical reactions of solutesoccur simultaneously, thus the investigations should finally lead to the calculation ofmass balances of the exchange terms between the different parts of the system. During2007 the project focused less on field data sampling and more on the integration ofdifferent models developed by the project partners as well as on different simulations.The field work performed by the VUB focused on gathering continuous data sets ofsurface water and groundwater temperatures and heads. Similar measurements have beenperformed at the Poederlee site of the Aa River in Flanders and then in June and autumnalso around Rogozynek in the upper basin of the Biebrza River in Poland. The Biebrza waschosen to serve a as second study case to validate the models and results. Thecontinuous survey of this data can give overview over the magnitude and the variation ofvertical groundwater flow in the hyporheic zone of the rivers. For the modeling thecoupling of the different ecological, ground- and surface water processes which havedifferent spatial and temporal dimensions, is the main challenge. GIS is used for datamanagement, while FEMME (Soetaert et al., 2002) became a platform for the integration ofthe different models. This platform allows a 1D-transient state simulation of several ofthe mentioned processes in the river simultaneously. Beside the validation of the modelswith datasets from the Biebrza, the coupling of the surface water model with groundwaterflow formulations is a further research point for the coming year.C. Anibas participated in the General Assembly of the European Geosciences Union inVienna, Austria, from 15.04.2007- 20.04.2007 and at the conference of the InternationalUnion of Geodesy and Geophysics in Perugia, Italy from 02.07.2007- 13.07.2007.C. Anibas, O. Batelaan and F. De SmedtBiebrza Wetland ResearchThe Biebrza River is located within the Biebrza National Park and is according to theRAMSAR Convention list one of the most important wetlands even on a worldwide scale.Situated in the north-eastern part of Poland, around 200 km from Warsaw, the parkcovers about 60.000 ha including the 156km long stretch of the Biebrza River. Thecatchment of the Biebrza River is divided into three geomorphologic units (Okruszko et al.1990): the Upper Biebrza, the Middle and the Lower Biebrza basin. The unique ecologicalvalue of the wetlands abundant in the Biebrza national park is, especially for Europeancircumstances, the result of the extensive usage of the area in the last decades comparedto other areas with similar character.
