Over 60 colleagues and friends attended, mainly from the Netherlands but also from Europe (including Belgium, England, France, Germany, Italy, Serbia) and abroad. This one day symposium included two main sessions and eleven talks. The morning session, chaired by Kees Kasse, was composed of five invited talks focusing on the main topics which dominated Jef's research during his fruitful career. The talk of Hugh French (University of Ottawa, Canada) focused on the cryostratigraphy in periglacial systems, while those of Huayu Lu (University of Nanjing, China) and Slobodan Markovic (University of Novi-Sad, Serbia) were devoted to synthesis about loess, both in China and in Europe (mainly Serbia), with an attempt to unravel the links between loess sedimentation and climate change. In between, Phil Gibbard (University of Cambridge) provided an overview of the fluvial response of temperate rivers to Pleistocene climate cycles. This presentation, mainly based on case studies from England, underlined the high influence of cold periods on fluvial activity and the importance of thresholds in the explanation of climate forcing. Finally, Gert Verstraeten (Leuven University, Belgium) established a link between Jef's research and the geomorphological modelling performed at Leuven. The final, well illustrated lecture was provided by Jef himself. He demontrated the importance of using a multi-analysis approach in event correlation instead of a multiproxy approach, in other terms to take into account all the components of a sediment study (sedimentology, stratigraphy, chronology) to underline the possible occurrence of thresholds or delayed responses, and also to avoid miscorrelations. The afternoon session was chaired by Hans Renssen (Vrije Universiteit Amsterdam). It provided the opportunity to some of Jef's former PhD students to present their past and present research. The presentations were arranged in chronological order, with Kees Kasse, Jef‟s first PhD Student (1985), as first speaker. Kees presented several case studies of his research focusing on the connections between fluvial activity, Holocene climate change and vegetation (palynology). Rene Isarin, who achieved his PhD in 1997, then reported about his job as a geoarchaeologist (specializing in environmental archaeology) in the Netherlands, presenting Jef as a necessary complement of Indiana Jones to underline the importance of performing palaeoenvironmental studies of archaeological contexts. Sasha Keestra (PhD in 2006) brought us back to the fluvial system, but focusing on present-day activity and the importance of both field work (including anecdotes derived from recent field work with Jef) and modelling. In contrast, fluvial archives were the main emphasis in the talk of Freek Busschers (PhD in 2007), dealing with the Rhine sedimentary complex in the Netherlands. This talk was illustrated by various 3D animations, providing the opportunity to discover the country "from all sides", and highlighting the necessary connections between fundamental research on fluvial archives and applied geosciences. The last talk was again given by Jef, and offered a well-illustrated overview of his research worldwide, leading us from America (Surinam, Canada) to Western and Central Europe (Netherlands, Italy, Portugal, Poland etc) and Asia (Indonesia, Siberia, China). The session was closed by a short speech by Bauke Oudega, the Dean of the Faculty of Earth Sciences, who honoured Jef's involvement in the administration of the Faculty and underlined Jef's support of field trips with students. A friendly reception closed the symposium, which (as during the coffee breaks and lunch) provided the opportunity for informal discussion amongst participants and, above all, 3 to pass informal congratulations to Jef. On behalf of the FLAG community, the executive board associated itself with all colleagues who attended the meeting, to wish to our past Chairman a pleasant, fruitful, and definitely 'fluvial' retirement.

  • The Age and Origin of the Gelderse Ijssel
    Netherlands Journal of Geosciences — Geologie en Mijnbouw | 87 - 4 | 323 - 337 | 2008 The age and origin of the Gelderse IJssel B. Makaske1*, G.J. Maas1 & D.G. van Smeerdijk2 1 Alterra, Wageningen University and Research Centre, P.O. Box 47, 6700 AA Wageningen, the Netherlands. 2 BIAX Consult, Hogendijk 134, 1506 AL Zaandam, the Netherlands. * Corresponding author. Email: [email protected] Manuscript received: February 2008; accepted: September 2008 Abstract The Gelderse IJssel is the third major distributary of the Rhine in the Netherlands and diverts on average ~15% of the Rhine discharge northward. Historic trading cities are located on the Gelderse IJssel and flourished in the late Middle Ages. Little is known about this river in the early Middle Ages and before, and there is considerable debate on the age and origin of the Gelderse IJssel as a Rhine distributary. A small river draining the surrounding Pleistocene uplands must have been present in the IJssel valley during most of the Holocene, but very diverse opinions exist as to when this local river became connected to the Rhine system (and thereby to a vast hinterland), and whether this was human induced or a natural process. We collected new AMS radiocarbon evidence on the timing of beginning overbank sedimentation along the lower reach of the Gelderse IJssel. Our data indicate onset of overbank sedimentation at about 950 AD in this reach. We attribute this environmental change to the establishment of a connection between the precursor of the IJssel and the Rhine system by avulsion. Analysis of previous conventional radiocarbon dates from the upper IJssel floodplain yields that this avulsion may have started ~600 AD.

Email: [email protected] area. We applied advanced hydraulic model simulations (1D–2D coupled set-up in HEC-RAS with 950 channel sections and 108 × 103 floodplain grid cells) to quantify the extent and magnitude of past floods in the Lower Rhine river valley and upper delta. As input, we used a high-resolution terrain reconstruction (palaeo-DEM) of the area in early mediaeval times, complemented with hydraulic roughness values. After conducting a series of model runs with increasing discharge magnitudes at the upstream boundary, we compared the simulated flood water levels with an inventory of exceeded and non-exceeded elevations extracted from various geological, archae- ological and historical sources.

    Netherlands Journal of Geosciences — Geologie en Mijnbouw | 91 – 1/2 | 1 - 3 | 2012 Palaeoenvironmental reconstructions: a tribute to the career of Jef Vandenberghe (editorial) C. Kasse* & H. Renssen Cluster Earth & Climate, Faculty of Earth and Life Sciences, Vrije Universiteit Amsterdam, De Boelelaan 1081, 1081 HV Amsterdam, the Netherlands. * Corresponding author. Email: [email protected]. Professor Jef Vandenberghe retired on the 1st of March 2011 after a long-lasting career at the Vrije Universiteit Amsterdam. He played a very important organisational and scientific role at our Faculty of Earth and Life Sciences and as a tribute to his career we organised a symposium for him entitled: ‘Palaeoenvironmental reconstructions – fluvial, eolian, periglacial – Evolution of ideas and approaches in the past 35 years’. The symposium on 1st April 2011 was well-attended, and colleagues, friends and former PhD- students filled this day with scientific presentations. To further highlight the scientific achievements of professor Vandenberghe, it was also decided to publish a special issue in the Netherlands Journal of Geosciences. As guest editors, we invited the participants of the symposium and other colleagues to contribute to this special issue. Because of the many contributions we received in the past year, a double issue has been produced. The content of this issue reflects the research interests of professor Vandenberghe over the last decades, focussing on the reconstruction of Quaternary sedimentary environments (fluvial: brooks and rivers; aeolian: coversands and loess), climate change (permafrost and periglacial structures) and modelling. The papers in this special issue have been arranged according to these themes. Vandenberghe started his career at Leuven University where he graduated in 1973 on the Geomorphology of the Zuiderkempen region in Flanders, Belgium (Vandenberghe, 1977).
