Solute transport modelling at the groundwater body scale: Nitrate trends assessment in the Geer basin (Belgium)Orban, Philippe 19 January 2009 (has links)
Water resources management is now recognized as a multidisciplinary task that has to be performed in an integrated way, within the natural boundaries of the hydrological basin or of the aquifers. Policy makers and water managers express a need to have tools able at this regional scale to help in the management of the water resources. Until now, few methodologies and tools were available to assess and model the fate of diffuse contaminants in groundwater at the regional scale.
In this context, the objective of this research was to develop a pragmatic tool to assess and to model groundwater flow and solute transport at the regional scale. A general methodology including the acquisition and the management of data and a new flexible numerical approach was developed. This numerical approach called Hybrid Finite Element Mixing Cell (HFEMC) was implemented in the SUFT3D simulator developed by the Hydrogeology Group of the University of Liège.
A first application of this methodology was performed on the Geer basin. The chalk aquifer of the Geer basin is an important resource of groundwater for the city of Liège and its suburbs. The quality of this groundwater resource is threatened by diffuse nitrate contamination mostly resulting from agricultural practices.
New field investigations were performed in the basin to better understand the spatial distribution of the nitrate contamination. Samples were taken for environmental tracers (tritium, CFCs and SF6) analysis. The spatial distribution of environmental tracers concentrations is in concordance with the spatial distribution of nitrates. This allows proposing a coherent interpretative schema of the groundwater flow and solute transport at the regional scale.
These new data and the results of a statistical nitrate trend analysis were used to calibrate the groundwater model developed with the HFEMC approach. This groundwater flow and solute transport model was used to forecast the evolution of nitrate concentrations in groundwater under a realistic scenario of nitrate input for the period 2008-2058. According to the modelling results, upward nitrate trends observed in the basin will not be reversed for 2015 as prescribed by the EU Water Framework Directive.
The regional scale groundwater solute transport model was subsequently used to compute nitrate concentrations in groundwater under different scenarios of nitrate input to feed a socio-economic analysis performed by BRGM. These computed concentrations were used to assess the benefit, for the users, linked to the reduction of contamination resulting from the changes in nitrate input. These benefits were compared to the costs associated to the implementation of the considered agri-environmental schemes that allow reducing the nitrate input to groundwater.

Estetiken & politiken : En semiotisk studie av Carl Johan De Geers affischer från 1960-taletLindahl, Mathias January 2015 (has links)
Den svenska alternativrörelsen frodades under 1960- och 1970-talet och introducerade för det svenska folket en rad alternativa tankar om hur ett samhälle kan se ut. Rörelsen ifrågasatte tidigare givna auktoriteter och lyckades på det viset väcka den politiska debatten om bland annat miljö, jämställdhet och utrikespolitik. Carl Johan De Geer, än idag aktiv som konstnär, var en av de framträdande figurerna i den här rörelsen. En av hans gärningar var en framgångsrik affischproduktion under 1960-talet som uttryckte en politik i symbios med alternativrörelsens politik. De affischer från denna produktion som jag analyserar är: Yttrandefrihet på torget, Skända flaggan, USA mördare, Vägra vapen och “Turkiet är inte bara...”. Jag har analyserat dessa affischer med en semiotisk bildanalys genom att ha delat upp affischerna i fyra olika meddelanden: det lingvistiska som behandlar texten, två meddelanden som fokuserar på bilden samt det multimodala som undersöker texten och bildens samverkan. Målet var att med denna uppdelning lyckas i en jämförelse hitta likheter och olikheter mellan dessa affischer, för att sedan i slutsatsen kunna skönja den dominerande estetiska utformningen och de dominerande politiska budskapen och hur de förhåller sig till varandra. Det jag fann i Carl Johan De Geers affischer var en aggresiv tonalitet och estetik som jag tolkade som ett sätt att tränga igenom bruset. Jag såg även ett rikt användande av liknelser som en teknik att förhöja språkets effektivitet. Alla affischer var influerade av alternativpolitik, som säkert är ett resultat av hur Carl Johan De Geer placerar sig själv på det politiska fältet men kanske även ett resultat av tillhörighet till gemenskapen. Slutligen kunde jag konstatera att alla affischer var väl förankrade för att undvika missförstånd och även för att inte kräva för mycket av den flyktige betraktarens öga. Detta gör dem dock inte ointressanta: jag fann nämligen att även om text och bild är förståeliga var för sig så adderade de ändå en dimension till varandra när de kombinerades.

En studie om De Geer-morän längs med Sveriges västkust / A Study of De Geer Moraine Along the Swedish West CoastKynde Hämberg, Josefine January 2021 (has links)
Majoriteten av geomorfologin i Sveriges landskap är produkten av den senaste nedisningen som avslutades för ca 8000 år sedan. De Geer-morän är en typ av moränavlagring som härstammar från denna nedisning. De Geer-moränavlagringarna har ett omdebatterat bildningssätt samt är landformer med en omtvistad innebörd i landskapen världen över. Vad är det som moränavlagringarna återspeglar? Är det avlagringar från svämmande glaciärer, avlagringar formade vid grundstötningslinjen för en ryckvis avsmältande glaciär eller kanske avlagringar bildade av sammanpressat material i basala sprickor hos en glaciär? Diskussionen om De Geer-moränen har varit långvarig och teorierna är många. Här är forskningen inte överens. Det förefaller också att studerad De Geer-morän på olika platser världen över inte nödvändigtvis behöver ha haft samma bildningsätt. I Sverige förekommer De Geer-morän främst i två områden, längs med kusten i Norrbotten och Västerbotten, samt vid den mellansvenska israndzonen. I dessa områden förekommer moränavlagringarna som små ryggar i svärmar med några meters höjd. De studier som gjorts i Sverige om De Geer-morän har förklarligt nog tenderat att fokusera på dessa två större områden. Men, utöver dessa två större områden finns det också ett mycket mindre område beläget längs med Sveriges västkust, ett område med samma typ av moränavlagringar. De Geer-moränen här, benämnda Hallands kustmorän, är både äldre och färre, dessutom är senaste nedisningens avsmältning i detta område mer ovisst. I denna uppsats gjordes ett försök till att övergripligt redogöra för några av de presenterade teorierna som föreligger De Geer-moränens bildningssätt. Uppsatsen syftar till att studera och kartera De Geer-moränen belägen längs med Sveriges västkust med hjälp av höjddata och sedan jämföra dessa avlagringar med den teori som presenteras i bakgrunden för denna uppsats. De Geer-moränen kommer även att jämföras med en isavsmältningsrekonstruktion gjord i programmet ICESHEET 1.0, med lokala karterade isräfflor i området samt även analyseras utifrån beskrivningarna till SGUs utgivna jordartskartor. Förhoppningen var att denna uppsatsen skulle kunna bringa mer klarhet om omfattningen och utbredningen av De Geer-moränen längs med Sveriges västkust. Resultatet som erhölls presenterades bland annat visuellt med framtagna kartbilder. Några av de slutsatser som kunde dras utifrån denna studie var att De Geer-moränen längs med Sveriges västkust är starkt påverkade av svallning och överlagring av yngre sediment vilket gjorde dem svåra att upptäcka i landskapet. Högst troligt är det att förekomsten av De Geer-morän längs med Sveriges västkust är större än vad som syns vid dagens marknivå på grund av överlagring, dessutom tyder mycket på att avlagringarna fortsätter ut i Kungsbackafjorden och Kattegatt. Det gick för det studerade området att se att det fanns ett samband mellan jorddjup och förekomsten av De Geer-morän. Ryggarna var främst avlagrade ovanpå drumliner och förekom främst i områden med ett jorddjup på ≥ 5m. Det gick inte att dra några slutsatser om De Geer-moränens bildningssätt i området. / Most of the geomorphology in the Swedish landscape is a product of the last deglaciation that ended about 8000 years ago. De Geer moraine is moraine deposits that has debated origins as well as debated implications worldwide. What message does the deposits send? What kind of conditions do they reflect? Are they perhaps the deposits of surging glaciers, or deposits formed at the grounding lines of melting glaciers or perhaps are they squeezed ridges formed in basal crevasses of glaciers? The discussion in research worldwide about the origin of these features have been going on for a long time and there is a lot of different theories about how the deposits are formed. The De Geer moraines in Sweden are mainly located in two larger areas, one of them being along the east coast in Norrbotten and Västerbotten, and the other one being a large belt of deposits that are located parallel to the big Swedish lake Vänern. The majority of the published articles about De Geer moraine in Sweden are therefore understandably about these two larger areas, however there are also a much smaller area of De Geer moraine along Sweden’s west coast. These deposits are called Halland’s coastal moraines and are not studied to the same extent as the other two areas. This bachelor thesis aims to, in a general way, describe some of the different theories there are about the formation of these ridges. The purpose of this thesis is to study and map the De Geer moraine along the Swedish west coast and compare them to the theory featured in the background of this paper. The ridges will then also be studied on the basis of a glacier melting reconstruction in the computer software ICESHEET 1.0, of ice striations in the area and lastly on the basis of the descriptions to the quaternary maps published by Geological Survey of Sweden. Hopefully, this paper will bring some clarity about the De Geer moraine ridges along the Swedish west coast. The results from this thesis were presented visually in different types of map sheets. Some of the conclusions that could be drawn from this bachelor thesis was that ridges along the Swedish west coast were both wave-washed and superimposed by younger sediments which therefore made them hard to both map and distinguish. There is a high probability that the occurrence of De Geer moraine is much larger in the area than what could be seen at today’s ground level. Also, the distribution of the ridges suggested that they continued out in Kattegatt and the Kungsbackafjord. In general, the ridges were superimposed on drumlins and there was shown to be a connection between soil depth and the occurrence of De Geer moraine, the ridges mainly occurred where the soil depth were ≥5 metres. Despite of this, no conclusion could be drawn about the formation of the features.

"Let us build an ark!" : Jonas De Geer and the negotiation of religion within radical nationalismLundström, Tomas January 2016 (has links)
This thesis illuminates meaning(s) of religion in a Swedish radical nationalist context. The empirical study is based on a critical text analysis of author Jonas De Geer, key ideology producer of Swedish radical nationalism. The research questions concern how the publications of Jonas De Geer, during the period 1996-2016, address issues related to religion and Christian imagery. The primary aim of the thesis – to study how the concept of religion is understood, negotiated and used in a Swedish radical nationalist context – is enunciated through an examination of how identity and antagonists are construed through the notions of religion in the material, and how these concepts change over time. An applied text analysis, informed by critical discourse analysis and corpus linguistics, constitutes the methodological framework of the study. The empirical analysis suggests that Christianity and national identity are construed as intertwined and natural, while Judaism is portrayed as the primary antagonist. Additionally, Islam and modernist ideals are depicted as weapons used by Jewish influence to dominate the West. Drawing on these empirical implications, the study concludes that religion functions as a racist configuration in De Geer's symbolic universe.

Impact of Climate Change on Groundwater ReservesGoderniaux, Pascal 24 February 2010 (has links)
Estimating the impacts of climate change on groundwater represents one of the most difficult challenges faced by water resources specialists. One difficulty is that simplifying the representation of the hydrological system, or using too simple climate change scenarios often leads to discrepancies in projections. Additionally, these projections are affected by uncertainties from various sources, and these uncertainties are not evaluated in previous studies. In this context, the objective of this study is to provide an improved methodology for the estimation of climate change impact on groundwater reserves, including the evaluation of uncertainties. This methodology is applied to the case of the Geer basin catchment (480 km²) in Belgium.
A physically-based surface-subsurface flow model has been developed for the Geer basin with the finite element model HydroGeoSphere. The simultaneous solution of surface and subsurface flow equations in HydroGeoSphere, as well as the internal calculation of the actual evapotranspiration as a function of the soil moisture at each node of the defined evaporative zone, improve the representation and calibration of interdependent processes like recharge, which is crucial in the context of climate change. Fully-integrated surface-subsurface flow models have recently gained attention, but have not been used in the context of climate change impact studies.
This surface-subsurface flow model is combined with advanced climate change scenarios for the Geer basin. Climate change simulations were obtained from six regional climate model (RCM) scenarios assuming the SRES A2 greenhouse gases emission (medium-high) scenario. These RCM scenarios were statistically downscaled using two different methods: the 'Quantile Mapping Biased Correction' technique and a 'Weather Generator' technique. Both of them are part of the most advanced downscaling techniques. They are able to apply corrections not only to the mean of climatic variables, but also across the statistical distributions of these variables. This is important as these distributions are expected to change in the future, with more violent rainfall events, separated by longer dry periods. The 'quantile mapping bias-correction' technique generate climate change time series representative of a stationary climate for the periods 2011-2040, 2041-2070 and 2071-2100. The 'CRU' weather generator is used to generate a large number of equiprobable scenarios simulating full transient climate change between 2010 and 2085. All these scenarios are applied as input of the Geer basin model.
The uncertainty is evaluated from different possible sources. Using a multi-model ensemble of RCMs and GCMs enables to evaluate the uncertainty linked to climatic models. The application of a large number of equiprobable climate change scenarios, generated with the 'weather generator', as input of the hydrological model allows assessing the uncertainty linked to the natural variability of the weather. Finally, the uncertainty linked to the calibration of the hydrological model is evaluated using the computer code 'UCODE_2005'.
The climate change scenarios for the Geer basin model predict hotter and drier summers and warmer and wetter winters. Considering the results of this study, it is very likely that groundwater levels and surface flow rates in the Geer basin will decrease. This is of concern because it also means that groundwater quantities available for abstraction will also decrease. However, this study also shows that the uncertainty surrounding these projections is relatively large and that it remains difficult to state on the intensity of the decrease.
