Interreg I / Ii : Cross-Border Cooperation
INTERREG I / II : CROSS-BORDER COOPERATION Euregio Meuse-Rhine: implementation and management in practice Speech by Mr K.H. Lambertz - Chair of the Monitoring Committee for the Euregio Meuse-Rhine Interreg Programme - Director of Euregio Meuse-Rhine - Minister-President of the German-speaking community of Belgium 1. General background and geographical situation In 1974, the governors of the Dutch and Belgian provinces of Limburg, together with the Chief Executive of the Cologne county administration, acted on the proposal made to them by the future Queen of the Netherlands, Princess Beatrix, during an official visit to Maastricht, to draw up draft arrangements for an association under which even closer cross-border collaboration could develop, along the lines of the Dutch-German Euregio project that had been running since 1957. This initiative was part of the new Community direction in regional policy, which in 1975 was to be provided with an instrument to assist economic development called the European Regional Development Fund (ERDF). In 1976, the principle of cross-border institutions was passed in law. Initially formed as an ad hoc association, the Euregio Meuse-Rhine was designed to promote integration between inhabitants on each side of the national borders. The area covers: • in Holland: the southern part of the Dutch province of Limburg; • in Germany: the city of Aachen, and the districts of Aachen, Heinsberg, Düren and Euskirchen, which make up the Aachen Regio, and • in Belgium: the entire province of Limburg. The province of Liège joined the Euregio Meuse-Rhine in 1978. In 1992, the German-speaking community of Belgium became the fifth partner in the Euregio Meuse- Rhine. -

We zullen moeten leren omgaan met grotere hoeveelheden water (zeespiegelstijging, grotere rivierafvoeren, extremere hoeveelheden neerslag), maar ook met grotere perioden van droogte. De zomer van 2018 staat wat dat betref nog vers in het geheugen. Beschikbaar zoet water is schaars op wereldschaal. Het meeste water op aarde is zout, en veel van het zoete water zit in gletsjers, of in de ondergrond. Slechts een klein deel is beschikbaar in meren en rivieren. Het IJsselmeer – inclusief Markermeer en Randmeren – is een grote regenton met kost- baar zoet water van prima kwaliteit voor een groot deel van Nederland. Het watersysteem functioneert nog goed, maar loopt wel op tegen de grenzen vanwege klimaatverandering. Door innovatie wegen naar de toekomst verkennen Het is verstandig om ons op die verandering voor te bereiden. Rijkswaterstaat verkent daarom samen met partners nu al mogelijke oplossingsrichtingen die ons in de toekomst kunnen helpen. Dat doen we door te innoveren en te zoeken naar vernieuwende manieren om met het water om te gaan. -
1 the DUTCH DELTA MODEL for POLICY ANALYSIS on FLOOD RISK MANAGEMENT in the NETHERLANDS R.M. Slomp1, J.P. De Waal2, E.F.W. Ruijg
THE DUTCH DELTA MODEL FOR POLICY ANALYSIS ON FLOOD RISK MANAGEMENT IN THE NETHERLANDS R.M. Slomp1, J.P. de Waal2, E.F.W. Ruijgh2, T. Kroon1, E. Snippen2, J.S.L.J. van Alphen3 1. Ministry of Infrastructure and Environment / Rijkswaterstaat 2. Deltares 3. Staff Delta Programme Commissioner ABSTRACT The Netherlands is located in a delta where the rivers Rhine, Meuse, Scheldt and Eems drain into the North Sea. Over the centuries floods have been caused by high river discharges, storms, and ice dams. In view of the changing climate the probability of flooding is expected to increase. Moreover, as the socio- economic developments in the Netherlands lead to further growth of private and public property, the possible damage as a result of flooding is likely to increase even more. The increasing flood risk has led the government to act, even though the Netherlands has not had a major flood since 1953. An integrated policy analysis study has been launched by the government called the Dutch Delta Programme. The Delta model is the integrated and consistent set of models to support long-term analyses of the various decisions in the Delta Programme. The programme covers the Netherlands, and includes flood risk analysis and water supply studies. This means the Delta model includes models for flood risk management as well as fresh water supply. In this paper we will discuss the models for flood risk management. The issues tackled were: consistent climate change scenarios for all water systems, consistent measures over the water systems, choice of the same proxies to evaluate flood probabilities and the reduction of computation and analysis time. -
41. the Meuse–Rhine Euroregion: a Laboratory for Police and Judicial Cooperation in the European Union*
41. THE MEUSE–RHINE EUROREGION: A LABORATORY FOR POLICE AND JUDICIAL COOPERATION IN THE EUROPEAN UNION* 1. Introduction Over the past few decades, economic and social integration within the European Union (EU) has rapidly gained momentum. This integration has been largely facili- tated by the Schengen Implementation Convention of 1990, which abolished border controls between the member states.1 However, this easing of border controls has also improved and expanded the opportunities for criminals to engage in cross-border illegal activities. Therefore, police and judicial cooperation has now become a high priority on the European Union’s agenda. The authorities in urbanized border areas are usually the first to be confronted by new developments in cross-border crime. As a result, opportunities for law- enforcement cooperation are quickly grasped, and practical innovations are devised as far as the conventions permit. Hence, border areas often serve as ‘laboratories’ for police and judicial cooperation. A clear example of this is the Meuse-Rhine Euroregion, located in the border areas of the Netherlands, Belgium and Germany. From a scholarly point of view, jurists have largely dominated the discussion about police and judicial cooperation (Corstens and Pradel 2002; Peers 2000; Sabatier 2001). This is easily explained by the fact that up until now criminologists have con- ducted relatively little empirical research on this topic. However, the Meuse-Rhine Euroregion is an exception to the rule, as several studies about police and judicial cooperation with regard to the area have been published over the years (Hofstede and Faure 1993; Spapens 2002, 2008a; Spapens and Fijnaut 2005). -

Silt in the Markermeer/Ijmeer
Silt in the Markermeer/IJmeer A study on the effectivity and efficiency of proposed approaches concerning the deterioration of the lake and its surroundings Student: Iris van Gogh (3220052) Environmental biology Ecology and Natural Resources Management Supervisor: Dr. J.N.M. Dekker Energy and Resources Copernicus Institute of Sustainable Development Faculty of Geosciences, Utrecht University December, 2012 Preface Since I was born in Lelystad, the capital of the county Flevoland in the Middle of the Netherlands, I lived near the Markermeer for about 18 years of my life. I still remember the time being on an airplane and my dad showing me the Markermeer and IJsselmeer below us. The difference in color (blue for the IJsselmeer, while green/brown for the Markermeer) was enormous, and I know now, this is mainly caused by the high amount of silt in the Markermeer. A couple of years later I was, again due to my father, at an information day about water, distributing ‘dropjes’, a typical Dutch candy, wearing a suit looking like a water drop, named ‘Droppie Water’. I think it were those two moments that raised my interest for water and even though I was not aware of it at that time, I never got rid of it. Thanks to the Master track ‘Ecology and Natural Resources Management’ which I started in 2011, my interest for water was raised once, or actually thrice, again. After my first internship, which was about seed dispersal via lowland streams and arranging my second internship about heavily modified water bodies in Sweden (which I planned for the period between half of December 2012 and the end of July 2013) I wanted to specialize this master track in the direction of water. -
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. -

During the operation, the Germans allegedly recovered a copy of the Market- Garden plan from the body of a British officer, who should not have carried it into combat. With this gun he engaged an enemy self propelled gun which was appoaching to attack. Luckily for the British tankers, most of the 88mm guns were sited for antiaircraft work and could not bear on the tanks as they used rubble around some factory buildings and a power station for cover. The unit set off to the bridge late and having traveled only a short distance the vanguard was halted by a strong German defensive position; the squadron could make no further progress.

While agreeing that Montgomery's drive towards the Ruhr should have priority, he still thought it was important to "get Patton moving again". Approximately 3, survivors of the 1st Airborne Division established themselves in the buildings and woods around Oosterbeek with the intention of holding a bridgehead on the north side of the Rhine until XXX Corps could arrive. Only his tank and one other made it this far; the other two were knocked out on the bridge, though one later rejoined the troop. -
Operation Market Garden WWII
Operation Market Garden WWII Operation Market Garden (17–25 September 1944) was an Allied military operation, fought in the Netherlands and Germany in the Second World War. It was the largest airborne operation up to that time. The operation plan's strategic context required the seizure of bridges across the Maas (Meuse River) and two arms of the Rhine (the Waal and the Lower Rhine) as well as several smaller canals and tributaries. Crossing the Lower Rhine would allow the Allies to outflank the Siegfried Line and encircle the Ruhr, Germany's industrial heartland. It made large-scale use of airborne forces, whose tactical objectives were to secure a series of bridges over the main rivers of the German- occupied Netherlands and allow a rapid advance by armored units into Northern Germany. Initially, the operation was marginally successful and several bridges between Eindhoven and Nijmegen were captured. However, Gen. Horrocks XXX Corps ground force's advance was delayed by the demolition of a bridge over the Wilhelmina Canal, as well as an extremely overstretched supply line, at Son, delaying the capture of the main road bridge over the Meuse until 20 September. At Arnhem, the British 1st Airborne Division encountered far stronger resistance than anticipated. In the ensuing battle, only a small force managed to hold one end of the Arnhem road bridge and after the ground forces failed to relieve them, they were overrun on 21 September. The rest of the division, trapped in a small pocket west of the bridge, had to be evacuated on 25 September. The Allies had failed to cross the Rhine in sufficient force and the river remained a barrier to their advance until the offensives at Remagen, Oppenheim, Rees and Wesel in March 1945. -
Half a Century of Morphological Change in the Haringvliet and Grevelingen Ebb-Tidal Deltas (SW Netherlands) - Impacts of Large-Scale Engineering 1964-2015
Half a century of morphological change in the Haringvliet and Grevelingen ebb-tidal deltas (SW Netherlands) - Impacts of large-scale engineering 1964-2015 Ad J.F. van der Spek1,2; Edwin P.L. Elias3 1Deltares, P.O. Box 177, 2600 MH Delft, The Netherlands; [email protected] 2Faculty of Geosciences, Utrecht University, P.O. Box 80115, 3508 TC Utrecht 3Deltares USA, 8070 Georgia Ave, Silver Spring, MD 20910, U.S.A.; [email protected] Abstract The estuaries in the SW Netherlands, a series of distributaries of the rivers Rhine, Meuse and Scheldt known as the Dutch Delta, have been engineered to a large extent. The complete or partial damming of these estuaries in the nineteensixties had an enormous impact on their ebb-tidal deltas. The strong reduction of the cross-shore tidal flow triggered a series of morphological changes that includes erosion of the ebb delta front, the building of a coast-parallel, linear intertidal sand bar at the seaward edge of the delta platform and infilling of the tidal channels. The continuous extension of the port of Rotterdam in the northern part of the Haringvliet ebb-tidal delta increasingly sheltered the latter from the impact of waves from the northwest and north. This led to breaching and erosion of the shore-parallel bar. Moreover, large-scale sedimentation diminished the average depth in this area. The Grevelingen ebb-tidal delta has a more exposed position and has not reached this stage of bar breaching yet. The observed development of the ebb-tidal deltas caused by restriction or even blocking of the tidal flow in the associated estuary or tidal inlet is summarized in a conceptual model.
