Abstract:
We present a three-step magnetic inversion procedure in which invariant quantities with respect to source parameters are inverted sequentially to give (1) shape cross section, (2) magnetization intensity, and (3) magnetization direction for a 2D (elongated) magnetic source. The quantity first inverted (called here the shape function) is obtained from the ratio of the gradient intensity of the total-field anomaly to the intensity of the anomalous vector field. For homogenous sources, the shape function is invariant with source magnetization and allows reconstruction of the source geometry by attributing an arbitrary magnetization to trial solutions. Once determined, the source shape is fixed and magnetization intensity is estimated by fitting the total gradient of the total-field anomaly (equivalent to the amplitude of the analytic signal of magnetic anomaly). Finally, the source shape and magnetization intensity are fixed and the magnetization direction is determined by fitting the magnetic anomaly. As suggested by numerical modeling and real data application, stepped inversion allows checking whether causative sources are homogeneous. This is possible because the shape function from inhomogeneous sources can be fitted by homogeneous models, but a model obtained in this way fits neither the total gradient of the magnetic anomaly nor the magnetic anomaly itself. Such a criterion seems effective in recognizing strongly inhomogeneous sources. Stepped inversion is tested with numerical experiments, and is used to model a magnetic anomaly from intrusive basic rocks from the Paraná Basin, Brazil.

Abstract:
Many approaches to magnetic data inversion are based on assumptions that source magnetization is homogeneous in direction and intensity. Such assumptions rarely can be verified with independent geologic information and are usually incorporated without further inquiry in the next steps of data interpretation. The use of magnetization direction invariants, such as the gradient intensity of the total field anomaly (equivalent to the amplitude of the analytical signal [ASA]) and the intensity of the anomalous vector field (IAVF), is effective for modeling sources with strong remanent magnetization, usually with unknown direction. Even in such cases, however, the assumption of uniform magnetization is understood but unchecked when seeking smooth or compact solutions from data inversion. We have developed a procedure to test the assumption of uniform magnetization for 2D sources. For true 2D homogeneous sources, the ratio of ASA to IAVF can be modeled with a binary solution (0 and 1) regardless of the real value of the magnetization. A procedure to provide convergence was applied, and its output solution was submitted to a binary test to verify the uniformity hypothesis. This technique was illustrated with numerical simulations and then used to reinterpret a ground magnetic profile across an intrusive diabase body in sediments of the Paraná Basin, Brazil, revealing the existence of two adjacent bodies that are homogeneous with different magnetization intensities.

Abstract:
Normal operation sedimentation basin flushing systems require large volumes of water, typically up ten times of the deposited sediment volume for efficient flushing. A complete sediment removal, can only be realized by combination of mechanical removal with drawdown flushing. This operation reaches much longer operation time resulting in water loss and reducing power and energy production of Mini Hydro Power Plant (MHPP). The objective of this study is to improve the flushing system of sedimentation basin based on a numerical approach. Fluid motion is described with non-linear, transient, second-order differential equations. A numerical solution of these equations involves approximating the various terms with algebraic expressions. The resulting equations are then solved to yield an approximate solution to the original problem. The simulation result shows that the 3D numerical modeling of flow in sedimentation basin gives the reasonable result to predict the suspended load movement in the flow.

Abstract:
Abstract Catch basins are designed to convey surface runoff into sewer systems. They are also found to be effective in retaining sediments. A number of factors can influence catch basin sediment capture efficiency, such as sediment size distribution, flow hydraulics and catch basin design. To better understand the influence of these factors, numerical simulations using the Eulerian-Lagrangian method were conducted to provide insights into flow fields and to predict sediment capture rates. The numerical model was validated using previous experimental measurements of flow field and sediment capture rates for sediment sizes larger than 0.25 mm. The influence of catch basin designs, including the bottom sump and inflow arrangements, was also studied, and an equation was developed for predicting the capture rate.

Na avaliação da maturidade de horizontes geradores e da história térmica de uma bacia com registro de atividade magmática é preciso considerar o efeito térmico imposto pela intrusão de corpos ígneos, como diques e soleiras. Dessa maneira, foi realizada a análise numérica transiente, pelo método de diferenças finitas, do fluxo térmico por condução provocado pela intrusão das soleiras básicas cretáceas nos horizontes geradores do Membro Assistência, Formação Irati, Bacia do Paraná. Esta análise, por sua vez, viabilizou a modelagem do parâmetro de reflectância da vitrinita nos estratos de folhelhos adjacentes às soleiras. Para tanto, foram utilizados os dados de seção de três poços, os quais registram espessuras de soleiras de até 4 m, e um poço com uma soleira de 27 m de espessura. Os poços localizam-se na porção sudeste da bacia. Na simulação numérica, foi considerado o processo de solidificação do magma ou de cristalização das suas fases minerais. A modelagem de reflectância da vitrinita baseou-se em um modelo pré-concebido da história térmica da Formação Irati, sendo os resultados desta simulação de maturidade do querogênio obtidos através do uso do programa EASY%Ro. Considerando-se os erros embutidos no modelo numérico e na discretização da história térmica dos estratos estudados, foram obtidos valores modelados de reflectância da vitrinita similares aos valores medidos nos poços pelo método tradicional. Somente no caso da seção com a soleira de 27 m de espessura houve uma grande diferença entre estes valores. Contudo, o alto coeficiente de correlação (0,95) entre estes possibilita a correção do efeito da espessura da soleira em análises futuras. Assim, a análise numérica simulou o halo térmico da soleira, caracterizado, segundo os dados de modelagem de refletância da vitrinita, por uma faixa acima e abaixo da soleira com espessura equivalente à espessura da soleira encaixada nos estratos geradores da Formação Irati. Essa metodologia de avaliação propicia um estudo preditivo das condições de maturidade de horizontes geradores em bacias ou áreas com magmatismo intrusivo, nas quais as análises do parâmetro de reflectância da vitrinita sejam ausentes ou escassas.
To evaluate the thermal maturity and thermal history of source rocks in basins with magmatic activity it is important to consider the thermal effects imposed by igneous intrusions, such as sills and dykes. This work uses the finite difference method for such evaluation, with the transient numerical analysis of heat conduction from Cretaceous diabase sills intruded into the source rocks of the Assistência Member, Irati Formation, Paraná Basin. This analysis has permitted modeling vitrinite reflectance of the shale strata adjacent to the sills. The data of four wells are used from the southeastern portion of the basin, with diabase thicknesses, respectively, of 1m, 2 m, 4 m and 27 m. The numerical simulation includes the process of magma solidification or mineral phase crystallization. The vitrinite reflectance modeling followed a pre-established thermal history of the Irati Formation, using the EASY%Ro program to simulate kerogen maturity levels. Considering the errors built into the numerical model and the thermal history discretisation of studied strata, the acquired values of modeled vitrinite reflectance closely resembled well data analyzed by the traditional method. Major discrepancies were observed in the case of the well containing a sill 27 m thick, but even in this case the high correlation coefficient (0,95) between the measured and calculated values is expected to permit correction of the sill thickness effect in future studies. The numerical analysis correctly simulated the thermal halo induced by sill emplacement, enabling vitrinite reflectance modeling to characterize it as a zone extending both above and below the sill with thicknesses similar to that of the sills. This evaluation methodology contributes to a predictive study of the maturity conditions of source rocks within basins or areas with intrusive magmatism where analysis of the vitrinite reflectance parameter are sporadic or absent.

Abstract:
Increasing dependence on groundwater in the Wakal River basin, India, jeopardizes water supply sustainability. A numerical groundwater model was developed to better understand the aquifer system and to evaluate its potential in terms of quantity and replenishment. Potential artificial recharge areas were delineated using landscape and hydrogeologic parameters, Geographic Information System (GIS), and remote sensing. Groundwater models are powerful tools for recharge estimation when transmissivity is known. Proper recharge must be applied to reproduce field-measured heads. The model showed that groundwater levels could decline significantly if there are two drought years in every four years that result in reduced recharge, and groundwater withdrawal is increased by 15%. The effect of such drought is currently uncertain however, because runoff from the basin is unknown. Remote sensing and GIS revealed areas with slopes less than 5%, forest cover, and Normalized Difference Vegetative Index greater than 0.5 that are suitable recharge sites.

Seawater-fresh groundwater natural equilibrium conditions in the aquifers of the Selç

Two dimensional density dependent cross sectional saturated flow and solute transport simulations were carried out to determine whether seawater intrusion has occurred in the Selç
uk sub-basin due to the imposed discharge or the determined salt-water in the western section of the aquifers represents natural interface equilibrium conditions. The numerical simulation model was calibrated using field measurements. The results of the simulations suggest that the seawater intrusion has occurred in the study area since the pumping activity increased in the region. Five scenarios were simulated for future predictions: (1) Present recharge and discharge conditions are maintained, (2) Discharge increases at a rate of the municipality need as a result of increasing population, (3) Discharge decreases by 12% from the present value, (4) Discharge decreases by 25% from the present value, and (5) No discharge occurs or recharge amount equals to the present discharge amount condition supplied to the aquifer. These scenario results suggest that seawater intrusion in the Selç
uk sub-basin would progress in the following years unless proper management measures are taken into consideration. KEYWORDS: seawater intrusion, density dependent groundwater flow, solute transport, contamination, Selç

Abstract:
Une prédiction de la réponse sismique des structures de génie civil (telles que les centrales nucléaires ou les barrages), doit faire face à plusieurs difficultés majeures compte tenu de la complexité du problème traité. Pour cela, la simulation de la source, la propagation des ondes sismique et les effets de site, ont été étudiés par différentes approches dernièrement. Récemment, des méthodes combinées avec des ordinateurs massivement parallèles se sont avérées très efficaces pour modéliser la propagation des ondes sismiques depuis la source jusqu’au site, dans des environnements géologiques tridimensionnels complexes. Cependant, la précision reste limitée en raison du caractère multi-échelle du problème et des grandes incertitudes sur les données à introduire dans le modèle (i.e. la caractérisation géométrique et cinématique de la source sismique, le modèle géologique et numérique du chemin de propagation). Pour cela, l’utilisation d'un modèle numérique régional capable de simuler le phénomène sismique de la source au site permettrait de mieux comprendre et de classer l'origine de ces incertitudes.Ce travail vise à étudier numériquement l'effet de la géologie locale et régionale sur la réponse sismique d’un bassin et plus particulièrement le site d’Argostoli situé sur l'île de Céphalonie (Grèce). Dans un premier temps, le code numérique utilisé dans ce travail (SEM3D) est vérifié à l'aide de trois cas canoniques. Les résultats obtenus montrent un bon accord avec les solutions de référence. Dans les cas d’un modèle numérique avec diverses échelles ou avec des géologies complexes, l’un des points clefs est la conformité du maillage numérique avec les interfaces géologiques, ce qui se traduit par l’augmentation du coût numérique. Grâce aux caractéristiques de la méthode numérique utilisée, pour contourner cette difficulté, une approche possible est l’utilisation des maillages “non-conformes” ou “not-honouring”. Une étude paramétrique sur la faisabilité de cette approche est ainsi réalisée afin de mettre en évidence l'influence de certains paramètres numériques sur les résultats obtenus.Par la suite, des études paramétriques de plusieurs scénarii sismiques sur le site d'Argostoli ont été réalisées. Concernant le chargement sismique, deux types de sources ont été étudiés : des sources ponctuelles et des failles étendues. L’étude avec les sources ponctuelles révèle un phénomène d'amplification et de piégeage des ondes dans le bassin, conduisant à un signal complexe et allongé, avec une énergie importante par rapport à une étude avec une géologie simplifiée. Pour le second type de source, la faille modélisée est proche de la surface. Cela permet d'étudier l’effets du bassin et du champ-proche sur la réponse sismique du site. En effet, le mouvement du sol à proximité d'une faille peut être différent du mouvement du sol observé loin de la source sismique. D’après les résultats obtenus, l'effet du bassin est plus marqué mais avec une amplification plus forte et des fréquences de résonance différentes. De plus, l'effet du champ-proche a été mis en évidence, marqué par de fortes impulsions de vitesse à certains endroits du bassin. L’ordre de grandeur des spectres de réponses obtenues est comparable à ceux obtenus lors des séismes de magnitude semblable qui ont eu lieu en 2014 au même endroit.Dans la dernière partie, une étude paramétrique sur des aspects numériques liées à la précision du calcul a été réalisée. Cette étude a permis d’augmenter la résolution fréquentielle de 7 Hz à 10 Hz avec des caractéristiques mécaniques de sols mous avec la même taille de domaine. Ces simulations ouvrent plus de questions sur l’interdépendance de la finesse de la résolution des données physiques et des maillages pour les calculs numériques. En conclusion, cette thèse correspond à une première étape dans la caractérisation numérique de la réponse sismique du bassin d’Argostoli et les effets dus au bassin, au type de source et à leurs interactions
A prediction of the seismic response of civil engineering structures that requires a high level of safety (i.e. nuclear power plants or dams) faces several major difficulties given the complexity of the problem being treated. To this end, the source simulation, seismic wave propagation and site effects have been studied by different approaches over the last two decades. Recently, numerical methods, such as the spectral element, combined with massively parallel computers have proved a good efficiency in modelling the seismic wave propagation from source to site in complex three-dimensional geological environments. However, the accuracy of these predictions remains limited due to the multi-scale nature of the problem and the large uncertainties in the data to be introduced into the model (i.e. the geometric and kinematic characterization of the seismic source, the detailed geological and numerical model of the source-to-site propagation path). Therefore, the use of a regional numerical model able to simulate the seismic phenomenon from source to site would allow a better analysis and classification of the origin of the associated uncertainties.This work aims to study numerically the effect of local and regional geology on the seismic response of a basin and precisely the Argostoli site located on the island of Kefalonia (Greece). Firstly, the numerical code used in this work (SEM3D) is verified using three canonical cases. The simulated results showed a good agreement with the reference solutions. In the cases of a numerical model with different scales or with complex geologies, one of the important difficulties is the conformity of the numerical meshes with the geological interfaces, that will result an increase in the numerical cost. Because of the characteristics of the used numerical method, one possible approach was to use the “non-conforming” or “not-honoring” meshes to overcome this difficulty. A parametric study on the applicability of this approach was then carried out in order to highlight the influence of some numerical parameters on the obtained results.Thereafter, parametric studies on several seismic scenarios in the Argostoli site were conducted. Concerning seismic loading, two types of source have been studied: point sources and extended faults. The study with point sources clearly revealed a phenomenon of amplification and trapping of waves in the basin, leading to a complex and elongated signal, with significant energy compared to a study with a simplified geology. For the second type of source, the modeled fault is close to the surface. It allows to study, in addition to the influence of the basin, the effect of the near-field on the seismic response of the site. Indeed, near-fault ground motion can be significantly different from ground motion observed far from the seismic source. Based on the results obtained, the basin effect is even more pronounced but with higher amplification and different resonance frequencies. In addition, the near-field effect has been highlighted, marked by strong velocity pulses at some locations in the basin. The order of magnitude of the obtained response spectra is comparable to the ones obtained during the earthquake sequence of similar magnitude that took place in 2014.In the last part, a parametric study (allowed by the development of computing power) on the numerical aspects related to the computational accuracy was carried out. With this study, it is possible to increase the frequency resolution from 7 Hz to 10 Hz with soft soil mechanical characteristics while keeping the same domain size. These simulations open even more questions on the interdependence of the fineness of resolution of physical data and meshes for numerical simulations. In conclusion, this thesis corresponds to a first step in the numerical characterization of the seismic response of the Argostoli basin and the effects due to the basin, the type of source and their interactions

COORDENAÇÃO DE APERFEIÇOAMENTO DO PESSOAL DE ENSINO SUPERIOR
A avaliação da recarga subterrânea e de sua variação temporal e espacial, em bacias hidrográficas, é essencial para estudos de sustentabilidade de recursos hídricos e requer, na maior parte das vezes, o uso de um modelo numérico de fluxo 3D. Geralmente, dados como mapas geológicos e pedológicos estão disponíveis, a localização e geometria das principais feições estruturais podem ser identificadas a partir de imagens de satélite, em ambiente SIG, e dados de hidrologia superficial e de elevação de terreno são fáceis de conseguir. No entanto, para se utilizar um modelo numérico que forneça uma primeira avaliação da sustentabilidade de uma explotação, é necessário alimentá-lo com dados de propriedades hidráulicas consistentes com a faixa de valores representativos dos tipos de rocha que compõe a bacia. Uma revisão de dados hidrogeológicos de uma série de localidades mostra que, enquanto as propriedades hidráulicas das rochas fraturadas apresentam uma grande variação em seus valores, quando analisadas de forma indiscriminada, ao serem agrupadas por tipo litológico, apresentam uma faixa de variação mais restrita (i.e. granito fraturado vs. gabro fraturado). Há um grande volume de dados relativos a projetos de disposição de lixo radioativo, mineração e engenharia civil, em diversos sítios ao redor do mundo, em que foram feitas investigações detalhadas do meio fraturado. Dados de um determinado maciço fraturado podem ser usados em outro, não investigado, como uma primeira aproximação, desde que possuam o mesmo tipo litológico e pertençam a ambientes tectônicos semelhantes. Este tratamento foi utilizado para modelar a vazão sustentável de uma pequena bacia de drenagem no Noroeste Fluminense. Dados relativos às estruturas dominantes e aos sistemas de fraturas foram extraídos de imagens de satélite, fotos aéreas e de afloramentos, e tratados em ambiente SIG. O modelo de fluxo subterrâneo foi construído com dados de elevação do terreno, mapas geológicos, registros hidrológicos históricos bem como mapas pedológicos e de uso da terra. O programa FEFLOW (Diersch, 1998) foi usado para simular a distribuição espacial e temporal da recarga subterrânea na bacia e diferentes cenários de explotação de água subterrânea. O modelo mostrouse capaz de fornecer uma primeira aproximação das reservas subterrâneas da bacia e de avaliar a relação entre o fluxo subterrâneo e dos cursos d’água superficiais, em condições naturais e nos cenários de explotação, sendo assim uma ferramenta útil para análises de sustentabilidade de exploração destes recursos.
The estimation of groundwater recharge and its spatial and temporal variability in a drainage basin is essential for sustainability assessments and requires, in most cases, the use of an appropriate 3D numerical flow and transport model. For most drainage basins, the bedrock and overburden geology maps exist, the location and geometry of major structural features can be identified using available GIS databases, and surface water and terrain elevation data at an appropriate scale are readily available. In order to use 3D models to provide an initial assessment of the sustainability of the groundwater resource extraction of a specific drainage basin, the 3D model has to be populated with hydraulic properties that are consistent with the range of values that are representative of the rock types that underlie the drainage basin. A review of hydrogeological data from a number of sites shows that while there is a wide range in the hydraulic properties of fractured rocks in general, the range for individual rock types is more constrained, (i.e. fractured granite versus fractured gabbro). There is a great amount of hydrogeological data from fractured rock masses that have been investigated in detail as part of nuclear waste, mining and civil engineering projects around the world. Data from a specific site can be used as a first approach in another one, not investigated, once they have the same geologic characteristics and tectonic environment. This approach was used to model the sustainable groundwater yield of a small drainage basin in Southeast Brazil. Data on major structures and fracture systems were extracted from satellite images, aerial photos and outcrop expositions using GIS environment. The groundwater flow model was constructed using terrain elevation data, geology maps, hydrological records, as well as soil type and land use maps. FEFLOW (Diersch, 1988) was used to simulate the spatial and temporal distribution of groundwater recharge in the basin, using different pumping scenarios. The model was capable to yield a good estimation of groundwater resources in the watershed, as a first approach, and to assess groundwater and surface water relations in natural conditions and in stress scenarios being a useful tool for sustainability analysis of groundwater exploitation.

k Menderes River Basin located in western Turkey has been facing continuous groundwater level decreases for the past 30 years. In dry periods, irrigation demand is completely met by pumping from groundwater system, which reduces water levels significantly. This provides enough storage to be recharged in wet seasons when streams are running. However, increased runoff in wet season are not utilized neither for irrigation nor for recharge and lost to the Aegean Sea without being infiltrated. Hence, surface artificial recharge methods can be useful to collect excess water in recharge basins, thus allowing infiltration to increase groundwater storage in wet seasons to be later utilized in dry seasons. A 2-D groundwater model is set up by using SEEP/W software. The material functions and parameters used in the model for saturated/ unsaturated conditions are taken from previous studies. Calibration was done to check the accuracy of input data and to control the validity of model. The amount of excess water that will be collected in recharge basins was estimated from flood frequency analysis. Concerning different probabilities, different scenarios were simulated to observe the increase in groundwater levels. Simulation results suggest that significant increase in groundwater storage could be achieved by applying artificial recharge methods. In addition to recharge basins, to reinforce the effect of artificial recharge, simulations were repeated with the addition of an underground dam at downstream side of the basin. Simulation results indicate that the increase in groundwater storage is not sufficient to warrant construction of the underground dam.

Full text
Abstract:
Snowmelt runoff in the mountainous eastern part of Turkey is of great importance as it constitutes 60-70% in volume of the total yearly runoff during spring and early summer months. Therefore, forecasting the amount and timing of snowmelt runoff especially in the Euphrates Basin, where large dams are located, is an important task in order to use the water resources of the country in an optimum manner. The HBV model, being one of the well-known conceptual hydrological models used more than 45 countries over the world, is applied for the first time in Turkey to a small basin of 242 km2 on the headwaters of Euphrates River for 2002-2004 water years. The input data are provided from the automatic snow-meteorological stations installed at various locations and altitudes in Upper Euphrates Basin operating in real-time. Since ground based observations can only represent a small part of the region of interest, spatially and temporally distributed snow cover data are acquired through the use of MODIS optical satellite. Automatic model parameter estimation methods, GML and SCE_UA, are utilized to calibrate the HBV model parameters with a multi-objective criteria using runoff as well as snow covered area to ensure the internal validity of the model and to generate a Pareto front. Model simulations show that the choice of study years and timing of satellite images affect the results and further suggest that more study catchments and years should be included to achieve more comprehensible conclusions. In the second part of the study, the calibrated HBV model is applied to forecast runoff with a 1-day lead time using gridded input data from numerical weather prediction models of ECMWF and MM5 for the 2004 snowmelt period. Promising results indicate the possible operational use of runoff forecasting using numerical weather prediction models in order to prevent or at least take precautions before flooding ahead of time.

Abstract:
Land subsidence which is defined as gradual settling or sudden collapse of Earth's surface, is a geohazard phenomenon that occurs worldwide. Land subsidence occurs in time mainly due to excessive groundwater abstraction. This problem occurs usually in semi-arid regions where the groundwater is the sole source of water. Eliminating the adverse effects of land subsidence requires careful observations on the temporal change of elevation coupled with groundwater flow modeling. In this study, numerical groundwater flow modeling technique is applied to a confined aquifer system in the Konya Subbasin of Konya Closed Basin (KCB), central Anatolia, Turkey. Groundwater head in the KCB has been declining with a rate of about 1m/year since early 1980s. Recent GPS observations reveal subsidence rates of 22 mm/year over the southern part of KCB. MODFLOW numerical groundwater flow model coupled with subsidence (SUB) package is used to simulate the effect of long term groundwater abstraction on the spatial variation of subsidence rates.

Abstract:
This chapter is an overview of recent studies of the movement of water, sediment, and nutrients across a principle piedmont slope, or bajada, of the Jornada Basin. Bajadas are extensive, gently sloping surfaces formed by the coalescence of alluvial fans and are a major landscape component of the basin and range province. Over the past four decades a considerable body of research has elucidated the form and function of alluvial fans (Bull 1977; Blair and McPherson 1994; Harvey 1997), but less attention has been paid to bajadas. In particular, the bajadas most neglected are those where channels converge and diverge at irregular intervals downslope. This type of bajada is found at the base of Summerford Mountain, the northernmost peak of the Doña Ana Mountains on the western edge of the Jornada Basin. For convenience, this bajada is hereafter referred to as the Summerford bajada. The research has involved rainfall simulation experiments on small plots, monitoring of two small watersheds on this bajada, and computer modeling of the processes operating in these watersheds and over the bajada as a whole. A detailed understanding of the hydrology and hydraulics of overland flow on this bajada requires a numerical model of the rainfall-runoff process. The objective of this chapter is to detail the model and draw conclusions from model simulations about hydrologic transports of sediment and nutrients across this bajada. Because these piedmonts are important surfaces in this desert (chapter 2) an understanding of their hydrologic and biogeochemical dynamics is crucial to understanding landscape dynamics in the basin and throughout arid regions. Summerford Mountain is a steep-sided, rocky inselberg (i.e., isolated mountain) that rises 380 m above the surrounding bajada to an elevation of 1,780 m. The mountain is composed of monzonite porphyry of Oligocene age (Seager et al. 1976) and has a fringing bajada on its northern and eastern sides. This study focuses on the bajada to the east, which extends 2.5 km to the basin floor at an average gradient of 4%.
