Door de vergrijzing zal de emissie van geneesmiddelen en röntgencontrastmiddelen naar het oppervlaktewater toenemen. De effecten van toenemende emissies op de waterkwaliteit worden versterkt bij lage rivierafvoeren, die naar verwachting steeds vaker en langduriger zullen optreden in een veranderend klimaat. In deze studie zijn prognoses gemaakt van de toekomstige concentraties van een aantal relevante organische microverontreinigingen in de Rijn en Maas in het jaar 2050. De voorspelde concentraties van diverse geneesmiddelen en röntgencontrastmiddelen in de Rijn en de Maas overschrijden de ERM-streefwaarden voor oppervlaktewater als bron van drinkwater. Sporen van enkele organische microverontreinigingen kunnen doordringen in het drinkwater.

De Atlantische steur (Acipenser sturio) behoort tot een ruim 200 miljoen jaar oude diergroep. Deze kraakbeenvissen overleefden de dinosauriërs. Echter, tussen 1920 en 1990 verdween de steur door toedoen van de mens uit vrijwel alle grote rivieren van West-Europa. Het is een geweldige uitdaging om deze oervis met beenplaten en vier snorharen voor uitsterven te behoeden

In 2014 zijn in het kader van het monitoringsprogramma "Monitoring contaminanten ten behoeve van de Nederlandse sportvisserij" 17 zoetwaterlocaties in Nederland bemonsterd. Van de gevangen rode alen zijn mengmonsters samengesteld voor de lengteklassen 30-40 cm en >45 cm en geanalyseerd op de aanwezigheid van dioxines, dioxineachtige- en nietdioxineachtige PCB's. De gevonden gehaltes sluiten goed aan bij de resultaten van 2013. Mengmonsters van kleine alen zijn onderzocht op 12 locaties en in 3 gevallen werden één of meerdere normen overschreden. De mengmonsters van grotere alen (>45 cm) voldeden op 9 van de onderzochte locaties niet aan één of meerdere normen. Naast aal uit de gesloten gebieden betrof dat ook aal uit het open gebied Amsterdam-Rijnkanaal bij Diemen. Per 1-1- 2015 behoort het Amsterdam-Rijnkanaal ook tot de gesloten gebieden. Anderzijds waren er ook locaties binnen de gesloten gebieden waar de mengmonsters aal wel voldeden aan de normen. Dit betrof beide locaties van het Volkerak.

One of the most endangered fish species worldwide is the European sturgeon Acipenser sturio. The River Rhine was home to an important sturgeon population that went locally extinct in the first half of the 20th century. In recent decades, many improvements of the ecological quality of the Rhine have taken place. Because the last remaining wild population of European sturgeon in the Gironde basin is very small and at considerable distance, it appears unlikely that rapid recolonization will take place if the Rhine is suitable again. That is why Stichting ARK, World Wildlife Fund (WWF) and the Dutch Anglers Association (Sportvisserij Nederland) have started a trajectory with the eventual reintroduction of the European sturgeon in the Rhine basin as the ultimate goal.

Future changes in extreme multi-day precipitation will influence the probability of floods in the river Rhine basin. In this paper the spread of the changes projected by climate models at the end of this century (2081–2100) is studied for a 17-member ensemble of a single Global Climate Model (GCM) and results from the Coupled Model Intercomparison Project Phase 3 (CMIP3) ensemble. All climate models were driven by the IPCC SRES A1B emission scenario. An analysis of variance model is formulated to disentangle the contributions from systematic differences between GCMs and internal climate variability. Both the changes in the mean and characteristics of extremes are considered. To estimate variances due to internal climate variability a bootstrap method was used. The changes from the GCM simulations were linked to the local scale using an advanced non-linear delta change approach. This approach uses climate responses of the GCM to transform the daily precipitation of 134 sub-basins of the river Rhine. The transformed precipitation series was used as input for the hydrological Hydrologiska Byråns Vattenbalansavdelning model to simulate future river discharges. Internal climate variability accounts for about 30 % of the total variance in the projected climate trends of average winter precipitation in the CMIP3 ensemble and explains a larger fraction of the total variance in the projected climate trends of extreme precipitation in the winter half-year. There is a good correspondence between the direction and spread of the changes in the return levels of extreme river discharges and extreme 10-day precipitation over the Rhine basin. This suggests that also for extreme discharges a large fraction of the total variance can be attributed to internal climate variability.

The main aim of this thesis is to analyse the climate change uncertainties that are important to take into account for long term water management and to explore the communication of these uncertainties. The study design combines natural and social scientific theories and methods and consists of three different elements: 1) an assessment of the dominant uncertainty for changes in mean and extreme precipitation over the Rhine basin; 2) an assessment of the impact of the main uncertainties on changes in flood risk and associated damage in the Rhine basin and 3) an exploration of the use of simulation gaming to communicate about climate change uncertainties to water managers.
Evaluation of modeled changes in extreme precipitation in Europe and the Rhine basin

In this study, we investigate the change in multi-day precipitation extremes in late winter in Europe using observations and climate models. The objectives of the analysis are to determine whether climate models can accurately reproduce observed trends and, if not, to find the causes of the difference in trends. Similarly to an earlier finding for mean precipitation trends, and despite a lower signal to noise ratio, climate models fail to reproduce the increase in extremes in much of northern Europe: the model simulations do not cover the observed trend in large parts of this area. A dipole in the sea-level pressure trend over continental Europe causes positive trends in extremes in northern Europe and negative trends in the Iberian Peninsula. Climate models have a much weaker pressure trend dipole and as a result a much weaker ( extreme) precipitation response. The inability of climate models to correctly simulate observed changes in atmospheric circulation is also primarily responsible for the underestimation of trends in the Rhine basin. When it has been adjusted for the circulation trend mismatch, the observed trend is well within the spread of the climate model simulations. Therefore, it is important that we improve our understanding of circulation changes, in particular related to the cause of the apparent mismatch between observed and modeled circulation trends over the past century.

The low-lying Netherlands is at risk from multiple threats of sea level rise, storm surges and extreme river discharges. Should these occur simultaneously, a catastrophe will be at hand. Knowledge about the likelihood of simultaneous occurrence or the so-called "compound effect" of such threats is essential to provide guidance on legislation for dike heights, flood barrier design and water management in general. In this study, we explore the simultaneous threats of North Sea storm surges and extreme Rhine river discharge for the current and future climate in a large 17-member global climate model ensemble. We use a simple approach, taking proxies of north-northwesterly winds over the North Sea and multiple~day precipitation averaged over the Rhine basin for storm surge and discharge respectively, so that a sensitivity analysis is straightforward to apply. By investigating soft extremes, we circumvent the need to extrapolate the data and thereby permit the model's synoptic development of the extreme events to be inspected. Our principle finding based on the climate model data is that, for the current climate, the probability of extreme surge conditions following extreme 20-day precipitation sums is around 3 times higher than that estimated from treating extreme surge and discharge probabilities as independent, as previously assumed. For the future climate (2070–2100), the assumption of independence cannot be rejected, at least not for precipitation sums exceeding 7 days.

Het algemene doel van het ACER project is om de gevolgen van klimaatverandering en adaptatie strategieën te onderzoeken voor het Rijnstroomgebied, zowel grensoverschrijdend in Duitsland en Frankrijk als voor het regionale waterbeheer in Nederland. ACER gebruikt een scenario analyse om effecten en oplossing te analyseren en vergelijken, onder de veronderstelling van verschillende klimaatverandering en sociaal-economische scenario’s voor 2050. Aan de basis van deze scenario aanpak staat een internationale groep van belanghebbenden en waterbeheerders uit verschillende bestuurslagen in het Rijnstroomgebied. Het is de vraag of de maatregelen die momenteel stroomopwaarts in Duitsland worden uitgevoerd positieve of negatieve effecten op de piekavoeren benedenstrooms hebben

Probability estimates of the future change of extreme precipitation events are usually based on a limited number of available global climate model (GCM) or regional climate model (RCM) simulations. Since floods are related to heavy precipitation events, this restricts the assessment of flood risks. In this study a relatively simple method has been developed to get a better description of the range of changes in extreme precipitation events. Five bias-corrected RCM simulations of the 1961–2100 climate for a single greenhouse gas emission scenario (A1B SRES) were available for the Rhine basin. To increase the size of this five-member RCM ensemble, 13 additional GCM simulations were analysed. The climate responses of the GCMs are used to modify an observed (1961–1995) precipitation time series with an advanced delta change approach. Changes in the temporal means and variability are taken into account. It is found that the range of future change of extreme precipitation across the five-member RCM ensemble is similar to results from the 13-member GCM ensemble. For the RCM ensemble, the time series modification procedure also results in a similar climate response compared to the signal deduced from the direct model simulations. The changes from the individual RCM simulations, however, systematically differ from those of the driving GCMs, especially for long return periods.

Alterra onderzocht samen met Wageningen Universiteit de gevolgen van klimaat- en landgebruikverandering op lage afvoeren in de Rijn. Hiervoor maakten ze gebruik van het grond- en oppervlaktewatermodel SIMGRO. Uit het onderzoek komt naar voren dat extreme klimaatscenario’s in 2050 zullen leiden tot aanzienlijk lagere afvoeren in de Rijn en bovendien een toename in de duur. Verder blijkt dat veranderingen in het landgebruik een veel kleiner effect hebben op lage afvoeren dan veranderingen in het klimaat. Hierdoor kunnen lagere afvoeren door klimaatverandering moeilijk opgevangen worden met alleen aanpassingen in het landgebruik

Estimates of future changes in extremes of multiday precipitation sums are critical for estimates of future discharge extremes of large river basins. Here we use a large ensemble of global climate model SRES A1b scenario simulations to estimate changes in extremes of 1–20 day precipitation sums over the Rhine basin, projected for the period 2071–2100 with reference to 1961–1990. We find that in winter, an increase of order 10%, for the 99th percentile precipitation sum, is approximately fixed across the selected range of multiday sums, whereas in summer, the changes become increasingly negative as the summation time lengthens. Explanations for these results are presented that have implications for simple scaling methods for creating time series of a future climate. We show that the dependence of quantile changes on summation time is sensitive to the ensemble size and indicate that currently available discharge estimates from previous studies are based on insufficiently long time series.

Given the need for continued quality control of surface waters used for the production of drinking water by state-of-the-art bioassays and biological early warning systems, the objective of the present thesis was to validate and improve some of the bioassays and biological early warning systems used for quality control of surface water. Although there is a decline in the (geno)toxicity of surface waters over the years as observed for example for the water from the River Rhine over last decades, there is still a need for continued quality control. Due to the lower (geno)toxicity, bioassays with increased sensitivity are needed

Climate change is likely to have an impact on the discharge of the European river Rhine. To base adaptation strategies, to deal with these changing river discharges, on the best scientific and technical knowledge, it is important to understand potential climate impacts, as well as the capacity of social and natural systems to adapt. Both are characterized by large uncertainties, at different scales, that range from individual to local to regional to international. This review paper addresses three challenges. Dealing with climate change uncertainties for the development of adaptation strategies is the first challenge. We find that communication of uncertainties in support of river basin adaptation planning generally only covers a small part of the spectrum of prevailing uncertainties, e.g. by using only one model or scenario and one approach to deal with the uncertainties. The second challenge identified in this paper is to overcome the current mismatch of supply of scientific knowledge by scientists and the demand by policy makers. Early experiences with ‘assess-risk-of-policy’ approaches analysis of options, starting from the resilience of development plans, suggests that this approach better responds to policy makers’ needs. The third challenge is to adequately capture the transnational character of the Rhine river basin in research and policy. Development and implementation of adaptation options derived from integrated analysis at the full river basin level, rather than within the boundaries of the riparian countries, can offer new opportunities, but will also meet many practical challenges.

The onset of downstream migration of European eels is accompanied by a cessation of feeding and the start of sexual maturation which stresses the link between metabolism and sexual maturation, also suggesting an important role for exercise. Exercise has been tested with eels in swim tunnels and was found to stimulate the onset of sexual maturation. In this study, we have investigated the interplay between migration and maturation in the field during the downstream migration of female silver eels. Temporal changes in migratory status and sexual maturation among silver eels of the upstream Rhine River system over 3 months of the migration season (August, September and October) were determined in biometrical parameters, plasma 17ß-estradiol and calcium levels, oocyte histology and gonadal fat levels. Furthermore, the ecological relevant parameters age as determined by otolithometry and health aspects indicated by haematocrit, haemoglobin and swim-bladder parasite load were measured. Silver eels were estimated to be 14 years old. A strong temporal progression in migratory stage was shown over the months of downstream migration. Catches probably represented a mix of reproductive migrants and feeding migrants of which the ratio increased over time. Furthermore, this study confirmed our hypothesis linking the migratory stage to early maturation as indicated by enlargement of the eyes, oocyte growth and fat deposition in the oocytes, exactly the same changes as found induced by exercise but not ruling out environmental influences. Migrants show extensive fat uptake by the oocytes, probably stimulated by the swimming exercise. In addition, at least 83% of the silver eels in this spawning run may have suffered from negative effects of swim-bladder parasites on their swimming performance.

Probability estimates of the future change of an extreme flood event are often based on a small number of available GCM or RCM projections. This limits the possibilities to assess extreme flood risks. A relatively simple method has been developed to create a wider statistical distribution for probabilistic risk management.
