Dynamic Control of Salt Intrusion in the Mark-Vliet River System, the Netherlands
Water Resour Manage (2011) 25:1005–1020 DOI 10.1007/s11269-010-9738-1 Dynamic Control of Salt Intrusion in the Mark-Vliet River System, The Netherlands Denie C. M. Augustijn · Marcel van den Berg · Erik de Bruine · Hans Korving Received: 11 January 2010 / Accepted: 8 November 2010 / Published online: 11 January 2011 © The Author(s) 2011. This article is published with open access at Springerlink.com Abstract The Volkerak-Zoom Lake is an enclosed part of the estuarine delta in the southwest of the Netherlands and exists as such since 1987. The current freshwater lake experienced a deterioration in water and ecological quality. Espe- cially cyanobacteria are a serious problem. To solve this problem it is proposed to reintroduce salt water and tidal dynamics in the Volkerak-Zoom Lake. However, this will affect the water quality of the Mark-Vliet River system that drains into the lake. Each of the two branches of the Mark-Vliet River system is separated from the Volkerak-Zoom Lake by a lock and drainage sluice. Salt intrusion via the locks may hamper the intake of freshwater by the surrounding polders. Salt intrusion can be reduced by increasing the discharge in the river system. In this study we used the hydrodynamic SOBEK model to run different strategies with the aim to minimize the additional discharge needed to reduce chloride concentrations. Dynamic control of the sluices downstream and a water inlet upstream based on real-time chloride concentrations is able to generate the desired discharges required to maintain the chloride concentrations at the polder intake locations below the threshold level and D. -
National Activities 2013
NATIONAL ACTIVITIES 2013 Traditionally the PIANC-AIPCN. Belgium Young Professionals started their year 2013 on January 17 with a culinary road trip. This time organized in Brussels, on which 15 gourmands participated. On March 26 2013, the annual general assembly of PIANC-AIPCN. Belgium took place. About 92 members participated in the assembly. This year, it was the Brussels region that organised the annual meeting in the neighbourhood of the Port of Brussels, on a place where you can still find the ancient warehouses and sheds. The assembly itself took place in one of the marvellous old wine cellars of the port. Ancient warehouses and sheds General assembly in the old wine cellers During the statutory part of the assembly, three new board members were appointed: ir. Freddy Aerts (Flemish authority), prof. dr. ir. Peter Troch (UGhent) and ir. Jean Polet (Besix) in replacement of ir. Luc Van Damme, prof. dr. ir. Julien De Rouck and ir. Jules Janssen. Ir. L. Van Damme, now retired, was appointed as treasurer of PIANC-AIPCN.be. During the academic part of the assembly, interesting presentations about the foundation and the construction of the Up-site-project, bordering the ABC canal were presented. Up-site building the new landmark of Brussels-North. Up-site building Port of Brussels from the top of the tower Tour & Taxis Top-information to the PIANC group The lunch was served in the Royal Depot of Tour & Taxis. Afterwards a numerous part of the PIANC members took the opportunity to climb up the highest residence tower in Brussels (140 m high), still in construction. -
The Ecology O F the Estuaries of Rhine, Meuse and Scheldt in The
TOPICS IN MARINE BIOLOGY. ROS. J. D. (ED.). SCIENT. MAR . 53(2-3): 457-463 1989 The ecology of the estuaries of Rhine, Meuse and Scheldt in the Netherlands* CARLO HEIP Delta Institute for Hydrobiological Research. Yerseke. The Netherlands SUMMARY: Three rivers, the Rhine, the Meuse and the Scheldt enter the North Sea close to each other in the Netherlands, where they form the so-called delta region. This area has been under constant human influence since the Middle Ages, but especially after a catastrophic flood in 1953, when very important coastal engineering projects changed the estuarine character of the area drastically. Freshwater, brackish water and marine lakes were formed and in one of the sea arms, the Eastern Scheldt, a storm surge barrier was constructed. Only the Western Scheldt remained a true estuary. The consecutive changes in this area have been extensively monitored and an important research effort was devoted to evaluate their ecological consequences. A summary and synthesis of some of these results are presented. In particular, the stagnant marine lake Grevelingen and the consequences of the storm surge barrier in the Eastern Scheldt have received much attention. In lake Grevelingen the principal aim of the study was to develop a nitrogen model. After the lake was formed the residence time of the water increased from a few days to several years. Primary production increased and the sediments were redistributed but the primary consumers suchs as the blue mussel and cockles survived. A remarkable increase ofZostera marina beds and the snail Nassarius reticulatus was observed. The storm surge barrier in the Eastern Scheldt was just finished in 1987. -
Making Lifelines from Frontlines; 1
The Rhine and European Security in the Long Nineteenth Century Throughout history rivers have always been a source of life and of conflict. This book investigates the Central Commission for the Navigation of the Rhine’s (CCNR) efforts to secure the principle of freedom of navigation on Europe’s prime river. The book explores how the most fundamental change in the history of international river governance arose from European security concerns. It examines how the CCNR functioned as an ongoing experiment in reconciling national and common interests that contributed to the emergence of Eur- opean prosperity in the course of the long nineteenth century. In so doing, it shows that modern conceptions and practices of security cannot be under- stood without accounting for prosperity considerations and prosperity poli- cies. Incorporating research from archives in Great Britain, Germany, and the Netherlands, as well as the recently opened CCNR archives in France, this study operationalises a truly transnational perspective that effectively opens the black box of the oldest and still existing international organisation in the world in its first centenary. In showing how security-prosperity considerations were a driving force in the unfolding of Europe’s prime river in the nineteenth century, it is of interest to scholars of politics and history, including the history of international rela- tions, European history, transnational history and the history of security, as well as those with an interest in current themes and debates about transboundary water governance. Joep Schenk is lecturer at the History of International Relations section at Utrecht University, Netherlands. He worked as a post-doctoral fellow within an ERC-funded project on the making of a security culture in Europe in the nineteenth century and is currently researching international environmental cooperation and competition in historical perspective. -

Dit rapport geeft beschrijving en resultaten van casus "Toekomstbestendige Mark-Dintel-Vliet boezem". In deze casus is gekeken of de ROBAMCI aanpak geschikt is voor een verkenning van de wisselwerking tussen vaarwegbeheer en het beheer van regionale keringen in de Mark-Dintel• Vliet boezem. Vier verschillende strategieën zijn beschouwd: 1 Niets doen 2 Alleen baggeren 3 Alleen dijken ophogen 4 Dijken ophogen en baggeren Uit de analyses blijkt dat over het gehele systeem bekeken strategie 3 het voordeligst is, gevolgd door strategie 4. Als echter per dijkvak beschouwd wordt welke strategie het voordeligst is, dan is een kenmerkende ruimtelijke verdeling zichtbaar. In het westen, waar de minimale dijkhoogtes het hoogst zijn vanwege de aanwezigheid van oude zeedijken, is de strategie. 'niets doen' het voordeligst. In het oosten is de voorkeursstrategie echter 'dijken ophogen en baggeren'. Deze strategie 4 is hier voordeliger dan stra_tegie3, aangezien het baggeren zorgt voor een kleinere toename in faalkans, waardoor pas op een later moment de duurdere investering van het dijkophogen nodig is.
