Abstract (sommario):
The OpenMI standard defines an interface that allows time-dependent models to exchange data at runtime. The migration of a flow simulation programme to OpenMI compliance usually requires changes in the source code or even a reorganisation of the programme sequence. Users of commercial flow simulation programmes depend on the software producer if they want to couple their models according to the OpenMI standard. We describe how we made the groundwater flow simulation programme Feflow OpenMI compliant without changing the source code: an OpenMI-compliant control application communicates with Feflow via remote procedure calls. A basic prerequisite for applying this method is an entry point into the flow simulation programme that allows to modify the model data during runtime and to implement the remote procedure calls. Feflow meets this requirement as it provides the interface manager (IFM). The mode of operation is explained with a simple test case including an inundation model and a Feflow groundwater model.

Abstract (sommario):
FEFLOW is a relatively new simulation code that was applied and tested systematically for the first time in Greece at Tirnavos alluvial basin, which is part of the eastern Thessaly plain. The aim of this exercise is to apply and test the applicability and versatility of FEFLOW in the simulation of groundwater flow of the Tirnavos basin aquifer system, which is located in eastern Thessaly-central Greece. From the compilation and calibration of the mathematical model, it can be concluded that FEFLOW is a very powerful tool with many practical applications and capabilities. Application of FEFLOW at Tirnavos basin was successful. As deduced by field data analysis, groundwater resources of the study area are overexploited, a fact which bears negative effects not only for the study area, but also for the surrounding area, which is much greater in extent. This fact was well reproduced in the simulation. It is therefore of utmost importance to rationally manage regional groundwater resources aiming at aquifer restoration (quantity and chemical quality) and the environmental protection of both the aquifer system and the depended and interrelated ecosystems, in accordance to the water related EC Directives.

Abstract (sommario):
Predicting and characterising groundwater flow and solute transport in engineering and hydrogeological applications, such as dimensioning tracer experiments, rely primarily on numerical modelling techniques. During software selection for numerical modelling, the accuracy of the results, financial costs of the simulation software, and computational resources should be considered. This study evaluates numerical modelling approaches and outlines the advantages and disadvantages of several simulators in terms of predictability, temporal control, and computational efficiency conducted in a single user and single computational resource set-up. A set of well-established flow and transport modelling simulators, such as MODFLOW/MT3DMS, FEFLOW, COMSOL Multiphysics, and DuMuX were tested and compared. These numerical simulators are based on three numerical discretisation schemes, i.e., finite difference (FD), finite element (FE), and finite volume (FV). The influence of dispersivity, potentially an artefact of numerical modelling (numerical dispersion), was investigated in parametric studies, and results are compared with analytical solutions. At the same time, relative errors were assessed for a complex field scale example. This comparative study reveals that the FE-based simulators COMSOL and FEFLOW show higher accuracy for a specific range of dispersivities under forced gradient conditions than DuMuX and MODFLOW/MT3DMS. FEFLOW performs better than COMSOL in regard to computational time both in single-core and multi-core computing. Overall computational time is lowest for the FD-based simulator MODFLOW/MT3DMS while the number of mesh elements is low (here < 12,800 elements). However, for finer discretisation, FE software FEFLOW performs faster.

Abstract (sommario):
hydrological modeling is commonly crossed by the solution of inverse problems and the estimation for non-linear parameters techniques. Despite this common scenario, the use of these guidelines is limited to the proper sampling of in-field data. This sampling involves a variety of data that generally have little availability, especially in regions where geographical and climatic variability does not allow a constant measurement. In this article, we present the analysis of a regional underground flow model using two techniques: pilot points (PP) and constant zones (CZ). This methodologies allow identifying properly if there are any biased parameters and heterogeneity of hydraulic properties. For this purpose, we developed a numerical variable density model that is limited with reinterpreted data from real measurements. For the CZ technique, the initial parameters are assigned according to its layer, and every layer is considered constant for parameter values; in contrast for PP technique, the initial parameters are assigned according to interpolations using in-situ point measurements. The developed model was applied in an area under the influence of the ITCZ, located in the middle valley of Magdalena (MMV). This area is important on the development of the country due to its contribution to GDP and has been subject to significant changes in land use, as a result of intense economic activities, for example, agriculture, hydroelectric power, and production of oil and gas. The established model shows a scarce link with the observed state variable (hydraulic head -K), this proves the importance of spatial heterogeneity in K. The model is calibrated in order to establish K (as an anisotropic variable that varies spatially), the porosity (η) and the specific storage capacity (Ss) in the PP and CZ, reducing a “mean square” error of state variable dependable on the observation points. The results show that the PP system approach provides a better heterogeneity representation and shows that each parameter is sensitive, and does not depend on other parameters, giving to the parameter evaluation results factual independence and authenticity. This research compiles a methodology to assertively restrict a highly parameterized inverse model with field data to estimate aquifer parameters that vary spatially at a regional scale

Abstract (sommario):
Groundwater and surface water are strongly connected. Therefore, understanding their interactions is important when studying the water balance of a complex aquatic system. This paper aims to present an integrated approach to study such processes, including a better understanding of the hydrological system behavior in the Ljubljansko polje (Slovenia). The study is based on multivariate statistical analyses of data collected over a long period, including the isotopic composition of groundwater, river water, and precipitation. The hydrology in the study domain was also simulated using a comprehensive modelling framework. Since boundary conditions are essential for simulating groundwater flow in a sensitive aquifer, a modelling system of rivers and channels (MIKE 11) and water flow and balance simulation model (WaSiM) were used to model river dynamics and the percolation of local precipitation, respectively. The results were then used as boundary conditions imposed on a transient state groundwater flow model performed in finite element subsurface flow simulation system (FEFLOW 6.2). Both the locations of recharge areas in the study domain and the calculated fluxes between the Sava River and the aquifer are graphically presented. The study revealed that a combination of the MIKE 11-FEFLOW-WaSiM tools offers a good solution for performing parallel simulations of groundwater and surface water dynamics.

Abstract (sommario):
The need of understanding transport processes of contaminants in groundwater has grownalong with the discovering of contamination of soil and groundwater due to industrialization.Mobility of an organic contaminant in the soil is affected by its partitioning to dissolvedorganic carbon, DOC. Partitioning of hydrophobic organic contaminants, HOCs, to DOC isdescribed by the contaminant’s KDOC value. The effects of DOC on transport processes oforganic contaminants with groundwater are still relatively unexplored even though somereviews have been carried out in this particular field of research. The aim of this thesis workwas to investigate transport processes for the PAH phenanthrene and the phthalate Di(2-ethylhexyl) phthalate, DEHP, with DOC by constructing a transport model with the computerprogram FEFLOW 6.1. The thesis work was performed as part of an ongoing Research &Development project investigating alternative remediation techniques at Domsjö industrialsite, located 2 km south of Örnsköldsvik. Generally, the groundwater at the site was characterized by low phenanthrene and DEHPcontent together with high DOC content. In the sampling points with highest reportedcontaminant concentration also DOC was present in highest concentrations. During theperformed literature study it was found that tabulated KDOC values for phenanthrene wasavailable but not for DEHP, which had to be calculated based on available KOC and KOWvalues. Five different modeling scenarios were developed: 1. Transport of phenanthrene with KDOC minimum value. 2. Transport of phenanthrene with KDOC maximum value. 3. Transport of phenanthrene with KDOC median value. 4. Transport of DEHP with KDOC calculated with KOC. 5. Transport of DEHP with KDOC calculated with KOW. Calculations of contaminant concentration in groundwater were made with an equation thatrequires both site and contaminant specific constants. These constants had to be estimatedduring this thesis work, which resulted in insecurities possibly affecting the model results.However, the minimum and the median value of KDOC showed best modeled phenanthreneconcentration after six years compared to measured values. Best result of modeledconcentrations of DEHP was obtained with KDOC calculated with KOC. Correlation analysis ofDOC and contaminants showed a significant correlation between DOC and phenanthrene at99% confidence level, and between DOC and DEHP at 90% confidence level.
I takt med ökad kännedom om industriellt förorenade områden har det också blivitbetydelsefullt att känna till de processer som påverkar transport av föroreningar medgrundvattnet. Rörligheten av en hydrofobisk organisk förorening, HOC, påverkas av dessfördelning till löst organiskt kol, DOC, och beskrivs med fördelningskoefficienten KDOC.Effekterna av DOC på föroreningstransporten är relativt okända trots att forskning harbedrivits inom området. Syftet med examensarbetet var att undersöka spridning av fenantren(ämnesklass PAH) och Di(2-etylhexyl)ftalat med DOC genom att konstruera enföroreningsspridningsmodell i datorprogrammet FEFLOW 6.1. Examensarbetet utfördes somdel i ett pågående Forsknings & Utvecklingsprojekt med syfte att utreda en alternativsaneringsteknik för Domsjö industriområde, 2 km söder om Örnsköldsvik. Generellt sett karaktäriserades grundvattnet på platsen av låg fenantren- och DEHP-halttillsammans med hög DOC-halt. På samma ställen där föroreningarna förekom i högstakoncentration var också DOC-koncentrationen som högst. Vid genomförd litteraturstudieåterfanns tabellerade KDOC-värden endast för fenantren. KDOC för DEHP saknades och fickberäknas med ekvationer baserat på förhållandet mellan KDOC och KOC respektive KOW. Femolika modelleringsscenarier utvecklades: 1. Spridning av fenantren med minsta tillgängliga KDOC-värde. 2. Spridning av fenantren med högsta tillgängliga KDOC-värde. 3. Spridning av fenantren med median KDOC-värde. 4. Spridning av DEHP med KDOC beräknat med KOC. 5. Spridning av DEHP med KDOC beräknat med KOW. Beräkning av föroreningarnas koncentration i grundvattnet gjordes med en ekvation somegentligen kräver både plats- och föroreningsspecifika konstanter. Då detta inte fanns att tillgågjordes uppskattning av värdena vilket resulterar i osäkerheter som kan ha påverkan påmodellerade resultat. De bästa modellerade koncentrationerna av fenantren efter sex årssimulering jämfört med uppmätta koncentrationer uppnåddes med minsta och median-värdeav KDOC. Bästa modellerade koncentrationerna av DEHP gavs av KDOC beräknat med KOC.Korrelationstest med DOC och respektive förorening visade en signifikant korrelation mellanDOC och fenantren vid 99% konfidensnivå, och mellan DOC och DEHP vid 90% konfidensnivå.

Ante la tarea de proponer nuevas metodologías para la caracterización y modelación de reservorios fracturados se propone la implementación en el software FEFLOW 7.1 de un modelo de fractura simple que represente la inyección de soluto implementada en el sitio de experimentación de rocas fracturadas de Ploemeur, Francia y considerando un escenario de inyección de un pulso de calor para observar la respuesta del modelo en función de unas consideraciones experimentales propuestas para el sitio. La calibración del modelo se realizó ajustando las curvas numéricas entregadas por el software a la respuesta másica experimental en conjunto con una curva calórica propuesta (y posible de encontrar en la zona), por medio de iteraciones desde un resultado inicial, obtenido desde los parámetros default del software y de acuerdo con la ley cúbica. El modelo conceptual por representar corresponde a una discontinuidad horizontal que separa 2 grupos de capas (layers) sobre el cual se simularon dos pozos (inyección y recuperación) separados horizontalmente por 10.8m. Los tiempos de llegada de trazador bordean los 30 minutos mientras que la respuesta calórica propuesta ronda las 50 horas. Dentro de los grandes controladores de la llegada de masa y calor al pozo de recuperación se encontraron la conductividad hidráulica y no así el espesor de fractura, además de tener efectos más intensos en el transporte calórico que en el másico. Factores como reacciones de sorción o efectos difusivos a esta escala local no tienen efectos notorios, sin embargo, a la hora de estudiar circulación a escala regional deben ser cuantificados y revisitados. El ajuste propuesto es bueno, tanto estadística como visualmente. Los análisis de sensibilidad efectuados sobre el ajuste muestran la existencia de propiedades críticas como la porosidad de los elementos circundantes y la dirección de gradiente hidráulico utilizado. La determinación en terreno de este parámetro resulta fundamental para obtener una primera aproximación fidedigna de los parámetros del acuífero y su determinación no debiera revestir mayor dificultad, ya que puede aprovecharse la implementación de los pozos para obtener dichos valores. Como suele suceder en toda simulación, resulta de primera necesidad la corroboración de los datos experimentales en terreno. En caso de que la configuración experimental no entregue los resultados propuestos para la calibración del transporte de calor, deben revisitarse los supuestos del modelo y acotar mejor el problema, ya que se estaría llegando a configuraciones hidrogeológicas que no representen de la mejor forma la situación real del acuífero. Finalmente, al considerar la extrapolación de los resultados a zonas de interés tanto chilenas como extranjeras debe tenerse en consideración el cambio de escalas y lo que esto conlleva: distintos tamaños de bloque y mayores tiempos de cómputo con requerimientos computacionales superiores. Así, implementar esta metodología es una buena primera aproximación al desafío del flujo y transporte en rocas fracturadas. Dentro de sus ventajas está la de necesitar pocos parámetros de entrada y pruebas de campo, por lo que puede considerarse como una opción viable antes de realizar modelos más complejos y robustos pero que requieren de mayor cantidad de información base.

Abstract (sommario):
Por años, la humanidad ha intentado aproximarse a las complejidades de la naturaleza, formulando principios y herramientas numérica para la modelación del escurrimiento subterráneo, el aprovechamiento de data medida en campo (piezómetros, registros de sondeos diamantinos y aforos) y análisis estadístico, permite proyectar y/o proponer modelos de flujo (circulación) dentro de unidades geológicas, como es el caudal de filtraciones una variable dependiente, y su importancia de ser estimado y drenado adecuadamente conllevaría a establecer indicadores de monitoreo y control del caudal dentro de masas geológicas. La información que fue recopilada e interpretada, está en función a la data obtenida de campo, los cuales permitieron proponer un modelo conceptual de flujo que considerase las características del o los macizos rocosos presentes en el Derrumbe 5, estableciéndose una primera estimación del caudal de filtraciones dentro de estas masas geológicas. El modelo conceptual de flujo y geológico inferido, fue implementado usando el código FEFLOW 7.1, permitiendo establecer una solución de aproximación numérica bajo la técnica de elementos finitos, asignándose condiciones iniciales y valores de permeabilidad para cada masa geológica de constitución compleja, la comparación de los datos observados en campo versus los resultados del modelo numérico, permitió establecer la curva de calibración, obteniéndose resultados RMS por debajo del 5%, Anderson (1986), valor aceptable en técnicas de modelación, los valores que fueron estimados para el caudal de filtración en las galerías se estimaron en el orden 2.1 l/s a 5.0 l/s basada en la interpretación de los datos medidos en campo (aforos) versus los estimados numéricamente.
For years, the human being has tried to approximate the complexities of nature, the principles and the numerical tools for the mode of superficial and subterranean clarification, the use of the data measured in the field (piezometers, records of diamond drilling and gauging) and its statistical treatment, allows to infer and / or predict flow models (circulation) within the geological masses, this flow of filtrations being a dependent variable, and its importance to be estimated and drained adequately, as well as to the monitoring indicators and control of the flow within geological masses. The information that was collected and interpreted, is based on the data obtained from the field, which allowed us to propose a conceptual flow model that considered the characteristics of the rock mass (s) present in Collapse 5, and establishing a first estimate of the flow of leaks within these geological masses. The conceptual model of inferred flow and geology was implemented using the FEFLOW 7.1 code, allowing to establish a numerical approximation solution under the finite element technique, assigning initial conditions and permeability values for each geological mass of complex constitution, comparing the data observed in the field versus the results of the numerical model, allowed to establish the calibration curve, obtaining RMS results below 5%, acceptable value in modeling techniques, the values that were estimated for the flow of filtration in the galleries were estimated in the order 2.1 l / s at 5.0 l / s based on the interpretation of the data measured in the field (aforos) versus the numerically estimated ones.

El trabajo de título se centró en la aplicación de la herramienta FEFLOW para la modelación y evaluación numérica de flujos de aguas subterráneas, en base a elementos finitos, en la zona saturada y no saturada del suelo. Se presenta un caso de estudio que fue analizado por la consultora de ingeniería ambiental Knight Piésold mediante la utilización, en conjunto, de otras herramientas de modelación como Visual Modflow y SEEP/W. Estos programas se complementan para analizar los flujos involucrados en la zona saturada y no saturada respectivamente, consignándose como una metodología a comparar frente a FEFLOW. Es así que se presenta como objetivo principal analizar la aplicabilidad, manejo y resultados numéricos de FEFLOW frente a lo realizado con Visual Modflow y SEEP/W. El desarrollo del trabajo consideró un análisis a las metodologías implementadas en la modelación de cada programa. De acuerdo a esto se presentan los resultados y pasos a seguir en la definición de la zona de modelación y sus condiciones de borde, interpolación topográfica y ajustes en la calibración de la zona saturada como de la no saturada de acuerdo a cada herramienta utilizada. Para complementar el estudio se realizó un análisis de sensibilidad del programa FEFLOW en función del número de elementos utilizados en la generación de la grilla de modelación y así conocer la influencia de esta variable en el modelo. Los resultados de ambas metodologías enfrentadas resultaron ser consistentes entre ellas y en línea a las consideraciones en la modelación. A su vez se analizaron las diferentes complejidades a enfrentar en la generación de un modelo con estas herramientas, por lo que la comparación no solo radica en elementos numéricos, si no también en las dificultades que el usuario debe hacer frente. Se concluye con un análisis a los objetivos y consideraciones más importantes observadas durante el estudio, tales como la utilización de programas basados en diferencias finitas y elementos finitos, la metodología en la caracterización de la zona no saturada, la modelación de una geometría compleja y la aplicabilidad del programa FEFLOW.

Abstract (sommario):
L’importanza dell’acqua sia per la vita, sia come componente dell’ecosistema globale sta diventando sempre più evidente. Essa è una risorsa che non solo soddisfa i bisogni fondamentali della popolazione umana, ma è anche vitale per tutti gli ecosistemi globali. Una domanda ricorrente è quella di trovare soluzioni per sopperire alla carenza di acqua che si avverte nei periodi estivi; questo “stato di calamità” va a dimostrare la scarsa conoscenza idrogeologica della risorsa idrica disponibile. Il tutto si traduce in una mancanza di strumenti idonei per affrontare con competenza e con tranquillità anche le situazioni più critiche che si possono presentare. L’obiettivo fondamentale di questo progetto è quello di mostrare come il monitoraggio delle falde sotterranee e l’applicazione della modellazione numerica allo studio degli acquiferi possa fornire un valido supporto scientifico alla progettazione e alle politiche di gestione per il corretto utilizzo e la salvaguardia delle risorse idriche del territorio. Nello specifico, è stato preso come riferimento il territorio del Bacino trasfrontaliero del Fiume Roia concentrando le analisi soprattutto nella parte sud dello stesso, in un’area di circa 1,8 km2, collocata poco a nord dell’abitato di Ventimiglia, dove il Fiume Roia si incontra con il suo maggiore affluente, il Torrente Bevera. L’acquifero presente in quest’area, per quantità e qualità, è uno dei più importanti serbatoi naturali della Liguria. Per quanto riguarda l’utilizzo della risorsa, infatti, le sue acque soddisfano i fabbisogni idrici sia del territorio francese (Mentone, Nizza, Montecarlo, ecc.) sia del territorio italiano (Ventimiglia, Bordighera, Imperia, Sanremo, ecc.), “dissetando” circa 350.000 utenze in Italia e circa 120.000 utenze in Francia. In particolare, questo studio idrogeologico, dopo una preventiva analisi ed un monitoraggio di dati di natura idrologica e idrogeologica (dati pluviometrici, idrometrici, piezometrici, di portata fluviale e di qualità delle acque sotterranee), ha affrontato la ricostruzione geometrico-strutturale del sottosuolo sulla base delle indagini geognostiche a disposizione grazie alle quali è stata evidenziata la presenza di un unico corpo acquifero, a falda libera, di spessore medio di circa 29,8 m, composto in prevalenza da ghiaie sabbiose, talvolta limose, con ciottoli e caratterizzato da un elevato grado di permeabilità (0,8-1 × 10-2m/s), limitato alla base da un substrato a bassa permeabilità costituito dai Flysch di Ventimiglia. E’ stata definita la caratterizzazione idrodinamica dell’acquifero mediante l’utilizzo dei dati raccolti durante una campagna di rilevamento piezometrica su 28 punti di misura nel periodo Luglio 2012 – Luglio 2013. Sulla base di queste conoscenze è stato realizzato il modello concettuale dell’acquifero, base fondamentale della modellazione numerica. Il sistema acquifero è stato quindi rappresentato, per mezzo di un modello numerico tridimensionale ad elementi finiti (FEM), con l’utilizzo del codice numerico FEFLOW (Finite Element subsurface FLOW system), operando in regime permanente e transitorio. I dati di input sono stati inseriti el sistema attraverso l’assegnazione di condizioni ai limiti (Boundary Condition) di carico idraulico, di trasferimento di flussi, di emungimenti e delle proprietà dei materiali (Material Properties) come la permeabilità, la porosità e l’infiltrazione. I risultati finali hanno permesso di stimare i quantitativi d’acqua presenti all’interno della porzione di acquifero in studio mettendo in risalto l’importanza e il ruolo che ricopre il fiume Roia e la quantità d’acqua che esso scambiata con la falda idrica che riesce a bilanciare e a mantenere in equilibrio tutto il sistema anche a fronte dei circa 44 × 106 m3 annui (circa 1,4 m3/s) prelevati dai pozzi presenti. Al fine di mostrare le potenzialità di questa tipologia di studio e ipotizzare possibili scenari di sfruttamento futuro 3 scenari di flusso dove si è ipotizzato un incremento dello sfruttamento della falda a scopo idropotabile. I risultati hanno messo in evidenza le enormi potenzialità di questo acquifero, il quale risulta in grado di sostenere fino ad un incremento del 70% delle attuali portate emunte, purché esse siano ben distribuite e non concentrate in un unico punto. Infine è stata effettuata la modellazione di trasporto dove sono stati analizzati due probabili scenari di inquinamento che hanno messo in evidenza quanto l’acquifero risulti essere suscettibile all’inquinamento idroveicolato da cui deriva, conseguentemente, la necessità di progettare adeguate misure per la sua salvaguardia, anche per l’importanza che esso ricopre come fonte strategica di approvvigionamento idropotabile.

A gestão adequada dos recursos hídricos é peça-chave para o desenvolvimento de uma região, seja urbana ou agrícola. O conhecimento acerca do impacto das mudanças climáticas e as diferentes atividades humanas sobre os recursos hídricos, em especial as águas subterrâneas, tornou-se essencial para tomadas de decisão corretas e sustentáveis. O Aquífero Rio Claro, localizado no município homônimo, é um aquífero raso e livre, composto por um pacote pouco espesso e predominantemente arenoso da Formação Rio Claro. Possui água naturalmente de boa qualidade e grande parte deste reservatório estende-se sob a área urbana do município. Este estudo estima os impactos da seca de 2013/2014 e o potencial de explotação do aquífero através do uso de modelagem numérica. Para as simulações utilizou-se o método dos elementos finitos por meio do algoritmo Feflow. A porção norte da área, mais agrícola, compreende a principal área de recarga do aquífero, enquanto que a porção sul é mais urbanizada e apresenta um grau de impermeabilização maior, que impacta negativamente as taxas de recarga. O balanço de fluxo calculou uma perda de 5,3% da água do armazenamento do aquífero durante o período de seca, que representou, na região, uma precipitação quase 30% menor que a média histórica. A grande maioria dos poços cadastrados no município extrai água de aquíferos mais profundos, perfazendo cerca de 450 m³/h. Em um cenário no qual o Aquífero Rio Claro fosse responsável por toda essa demanda de água subterrânea durante todo o período de seca, o aquífero perderia cerca de 6,6% da água de seu armazenamento. O bombeamento dos poços atingiria aproximadamente 19% da recarga do aquífero, portanto, o aquífero tem potencial para comportar tal volume de explotação. No entanto, a concentração dos poços no distrito industrial e na área urbana do município representa um alto risco para o aquífero e para o abastecimento nestas áreas, com alteração da dinâmica de fluxo entre as porções norte e sul e interferência nas vazões dos poços.
Proper management of water resources is a key player in regional development, whether urban or agricultural. The knowledge about the impacts of climate changes and human activities on water resources, especially groundwater, it has become essential for making correct and sustainable decisions. The Rio Claro Aquifer, located in the homonymous city, is a shallow and unconfined aquifer, composed of a thin layer of Rio Claro Formation sandstones. It has good quality water in natural conditions and a significant part of this reservoir is located below the urban area. This study estimated the impacts of the drought of 2013-2014 and the potential exploitation of the aquifer using numerical modeling. Finite elements method by Feflow algorithm was used for the simulation. The northern portion, more agricultural, encompasses the main recharge area, while the southern portion is more urbanized and has a higher waterproofing coverage impacting negatively on the recharge rates. The water budget showed a loss of 5.3% of the aquifer storage during the dry season. The precipitation was almost 30% lower than the average in this region. The majority of registered wells in the city extracts water from deeper aquifers reaching about 450 m³/h. In a scenario in which the Rio Claro Aquifer is responsible for all groundwater demand throughout the dry season, the aquifer would lose about 6.6% of its water storage. The pumping wells reaches approximately 19% of the aquifer recharge, therefore the aquifer can support this exploitation volume. However, the spatial concentration of the wells in the industrial district and the urban area pose a high risk to the aquifer and the groundwater supply in these areas, by changing the water flow dynamics between the northern and southern portions and interference in the well rates.

Abstract (sommario):
Utilisée depuis des milliers d’années sous ses manifestations naturelles par l’Homme, cette ressource fait l’objet d’une exploitation commerciale depuis seulement le XXe siècle, à destination du chauffage de bâtiments, de certains usages industriels ainsi que de la production d’électricité. La France compte parmi les pionniers concernant l’usage direct de la chaleur alors qu’aucune filière industrielle n’est véritablement effective pour la production d’électricité d’origine géothermique. Le projet sélectionné, intitulé FONGEOSEC, a pour objectif la conception et la réalisation d’un démonstrateur innovant préindustriel d’une centrale géothermique haute enthalpie exploité par cogénération d’électricité et de chaleur. Un travail de recherche et développement, conduit par un consortium composé de partenaires industriels et scientifiques, vise au lancement de la filière industrielle géothermique haute température en France. L’objectif général des travaux de thèse porte sur une meilleure compréhension globale des comportements hydrauliques, massiques et thermiques des formations profondes en réponse à une sollicitation anthropique de longue durée. Il s’agit d’identifier les paramètres clés régissant la réponse du complexe réservoir à la suite d’une exploitation géothermique. Un point particulier sera consacré à caractériser la part de chacun des modes de transport de chaleur en milieu poreux – conduction thermique, convection libre et forcée – dans l’établissement des performances thermiques de l’ouvrage considéré. Plusieurs dispositifs techniques d’exploitation seront proposés afin de réduire les incertitudes associées au système géothermique souterrain et garantir le succès du projet FONGEOSEC. L’impact des mécanismes thermo-convectifs au voisinage des forages d’exploitation géothermique de grande profondeur reste peu documenté, a fortiori dans le cas de dispositifs déviés adoptant une complétion particulière. L’outil retenu pour l’évaluation des performances du dispositif au contact de l’encaissant est la modélisation numérique distribuée. La variabilité des propriétés physiques de l’hydrosystème, de la conception et des modalités d’exploitation du dispositif sur le comportement hydraulique et thermique de l’exploitation est envisagée selon différentes approches développées à partir de modèles numériques 3D
Used for thousands of years under its natural manifestations, this resource has been commercially exploited since the twentieth century, for the heating of buildings, certain industrial uses and the production of electricity. France is one of the pioneers in the direct use of heat, whereas no industrial cluster is truly effective for the production of geothermal electricity. The selected project, FONGEOSEC, aims to design and produce an innovative pre-industrial demonstrator of a high enthalpy geothermal power plant operated by cogeneration of electricity and heat. A research and development project, led by a consortium of industrial and scientific partners, aims to launch the high-temperature geothermal industrial sector in France. The general objective of this thesis is to improve the understanding of the hydraulic, mass and thermal behavior of deep porous formations in response to long-term anthropogenic stress. The aim is to identify the key parameters governing the response of the reservoir complex related to geothermal operation. A particular point will be devoted to characterize the part of each mode of transport of heat in porous medium – thermal conduction, free and forced convection – in the establishment of the thermal performances of the geothermal power plant. Several technical operating devices will be proposed to reduce the uncertainties associated with the underground geothermal system and guarantee the success of the FONGEOSEC project. The impact of thermo-convective mechanisms in the vicinity of deep geothermal borehole remains poorly documented, especially in the case of deviated wells with a complex inner geometry. The evaluation of the hydraulic and thermal performances of the device, based on 3D numerical modeling, is conducted according to different approaches

Abstract (sommario):
Le bassin hydrologique du Barada et de l’Awaj est le plus important et le plus intensément exploité de Syrie. Le sous bassin amont de la rivière Awaj occupe la partie sud-ouest de ce bassin. Dans cette région aride, l’eau souterraine représente la principale réserve et ressource de production d’eau. Dans l’optique de caractériser le fonctionnement du système hydrogéologique multicouche local et de calculer un bilan hydrologique pour l’aquifère superficiel, une méthodologie multi techniques couplant hydrochimie, isotopie et hydrodynamisme a été déployée. L’analyse détaillée des données hydrochimiques recueillies a mis en évidence la grande variabilité du fond géochimique local, directement fonction de la stratigraphie. Cette complexité stratigraphique induit une vision hydrogéologique complexe de nombreux corps aquifères. L’évolution de la chimie des eaux révèle la prépondérance du phénomène de dissolution/précipitation des roches carbonatées comme principal mécanisme de contrôle de l’hydrochimie, devant l’hydrolyse des silicates, la dissolution du gypse et l’échange ionique. En conséquence il n’a pas été possible de déduire de l’hydrochimie des eaux les preuves d’une recharge par drainance ascendante depuis l’aquifère du jurassique vers les aquifères superficiels, bien que la similarité des faciès hydrochimiques tend à consolider l’hypothèse d’une origine unique des eaux, sans toutefois permettre une identification des chemins d’écoulement. Les données isotopiques indiquent quant à elles, une infiltration importante et rapide des eaux météoritiques, avant qu’une importante phase d’évaporation n’ait lieu. Ainsi, l’important flux d’infiltration qui se produit essentiellement dans la partie montagneuse de la zone, représente la principale source de recharge du système aquifère multicouche régional. De ce fait la zone d’étude peut se subdiviser en deux sous régions : la première (A) se caractérise par une dissolution active et des flux de circulation d’eau souterraine fortement orientés verticalement vers la profondeur, alors que la seconde (B) est caractérisée par des écoulements peu profonds associés à des interactions hydrochimiques avec les roches encaissantes. Les résultats de la modélisation hydrodynamique du système mettent en évidence la connexion hydraulique entre l’aquifère profond du Jurassique et les aquifères surincombants par le biais d’une drainance ascendante. Le bilan hydrologique de l’aquifère se surface a ainsi pu être appréhendé : les principaux flux de recharge proviennent de l’infiltration des eaux météoritiques mais également de l’écoulement latéral du Jurassique dans la partie montagneuse. La drainance ascendante depuis le Jurassique dans la partie aval est également non négligeable. Du point de vue des sorties, le flux d’écoulement le plus important se situe en direction de l’est vers le centre du bassin. Ce constat permet de concevoir que La sous bassin amont de le rivière Awaj est la principale zone de recharge occidentale du bassin de Barada et Awaj
Barada and Awaj basin is the most important and extensively used water basin in Syria. The upper part of Awaj River occupies the southwestern part of this basin. In this arid region, groundwater is considered to be as a main source of water supply. In order to assess the main features which characterize the hydrogeological system in this area and calculate the water budget of the first aquifer horizon, a multi approach methodology using hydrochemistry, environmental stable isotopes and groundwater modeling were used as integrated tools. The detailed description of hydrogeochemical conditions has underlined the very complex variability of the stratigraphic sequences and hence the numerous hydrogeological units within the study area. Hydrogeochemical evolution reveals the domination of dissolution/precipitation of carbonate rocks as a main mechanism controlling groundwater chemical composition and to less extend, the silicate hydrolysis, dissolution of gypsum and reverse ion exchange. Consequently, hydrochemical patterns did not give enough evidences for the expecting of huge feeding flow from the Jurassic aquifers towards the Neogene/Quaternary aquifer. The similarity in water type tends to express the existence of a unique hydrochemical system where the individualised groundwater flow paths are difficult to delineate. The isotope compositions imply an important rapid infiltration of atmospheric precipitation before significant evaporation takes place. Hence the infiltrated precipitation provides the main source of groundwater recharge all over the study area and mainly throughout the mountainous parts. The study area can be dividing into two main sub-regions. The sub-region (A) which characterizes by active dissolution phenomena and deep vertical groundwater flow. And sub-region (B) which characterizes by a shallow horizontal flow component associated with active interaction between groundwater and hosting rocks. The result of groundwater model indicates a hydraulic connection between the deep aquifers and the overlying first aquifer through the upward leakage of groundwater. The components of the water budget of the first aquifer had determined. The lateral discharge from the Jurassic aquifer as well as the meteoric recharge is the most important recharging component of this budget. The upward leakage of groundwater from deeper aquifers also plays an important role. However, the lateral discharge from the eastern boundary is the largest discharge component which indicates that the study area can be considered as a main recharge region of the western side of the Barada and Awaj Basin

Abstract (sommario):
L’objectif est la construction numérique d’un modèle 3D régional de la plaine de Sidi Bouzid permettant la quantification du transfert hydrique et du rôle des crues sur le processus de recharge. Des simulations numériques de l’écoulement ont été réalisées à l’aide de Feflow et validées par des données mesurées in situ. Une conceptualisation des paramètres d’entrée a été réalisée afin de contourner l’absence de données mesurées. L'hétérogénéité de la zone non saturée a un impact significatif sur la variation du flux vertical et la propagation du front d’humidité. Les résultats obtenus en 1D ont été spatialisés à l’échelle de la plaine avec l’objectif de quantifier l’ensemble des flux d’écoulements. L’originalité réside, d’une part, dans la détermination des conditions aux limites appliquées à la surface du sol à partir des hydrogrammes des crues enregistrés et, d’autre part, au modèle conceptuel limitant l’évaporation. Le modèle hydrodynamique a mis en évidence que le bilan hydrique est fortement excédentaire. Les simulations de l’écoulement ont montré que l’approche des épandages de crues au niveau des périmètres surestime la recharge artificielle de la nappe
The aim of this study is to set up a 3D regional model to quantify water flux in unsaturated-saturated zones and the role of floods on the recharge process. Therefore, numerical flow simulations were conducted using the finite element Feflow that will be validated by measured data. A conceptualization of input parameters was carried out to overcome the absence of measured data. The heterogeneity of the vadose zone have a significant impact on the variation of the vertical flow, the residence time and the propagation of wetting front in the unsaturated zone. The results obtained in 1D were then used to quantify groundwater recharge of the entire area of the study site. The original approach is to derive the time-dependent hydraulic boundary condition of water level at the soil surface of the spreading perimeters by measured flood hydrographs and to develop a limited conceptual model of water uptake by evaporation. The hydrodynamic model showed that the water balance is very important. Flow simulations have shown that the perimeter flooding approach overestimates the artificial recharge of the aquifer
