Abstract:
Abstract. This paper presents a salt intrusion model for the Pungue estuary with the aim to determine the minimum discharge required to prevent the salt intrusion from reaching the water intake situated 82 km from the estuary mouth. The Pungue river is shared between Zimbabwe and Mozambique and has a large variation in precipitation and runoff. The mean monthly discharge can be as low as 8 m3/s and as high as 893 m3/s. The second largest city of Mozambique, Beira, relies on the Pungue for its water supply. In the dry season it frequently occurs that the water intake has to be ceased because the salinity of the Pungue is too high. The salt intrusion model used in this paper is based on a fully analytical and predictive theory which is confronted with measurements of salt intrusion and estuary topography. The paper presents the collection of estuary characteristics and the salt water intrusion measurements that were obtained by field measurements in 1993 and 2002. Using these data the salt intrusion model has successfully been applied. During salinity intrusion measurements in the dry season of 1993 it was observed that sand banks in the middle zone of the estuary prevented the salt water from intruding further upstream, resulting in lower salinity levels upstream than the theoretical salt water intrusion model predicts. This effect occurs during ebb of neap and average tides and can reduce the salt water intrusion by 10 km. The model indicates that in a natural situation a minimum monthly discharge of 12 m3/s is required to maintain acceptable salinity levels during high water and spring tide near the water intake. The actual water discharge upstream of the water intake has to be higher, since this minimum discharge does not take into account the water abstracted for irrigation and/or urban water supply. Current water abstractions lead to salt water intrusion near the water intake at approximately 10% of the time. The model indicates that an additional water abstraction of 5 m3/s will lead to an increase in salt water reaching the intake at 10% of the time. During neap tide the sand banks act as a temporary natural salt intrusion barrier reducing the chance of salt water reaching the water intake.

Abstract:
Abstract. Salt intrusion in the Pearl River estuary (PRE) is a dynamic process that is influenced by a range of factors and to date, few studies have examined the effects of winds and waves on salt intrusion in the PRE. We investigate these effects using the Coupled Ocean-Atmosphere-Wave-Sediment Transport (COAWST) modeling system applied to the PRE. After careful validation, the model is used for a series of diagnostic simulations. It is revealed that the local wind considerably strengthens the salt intrusion by lowering the water level in the eastern part of the estuary and increasing the bottom landward flow. The remote wind increases the water mixing on the continental shelf, elevates the water level on the shelf and in the PRE and pumps saltier shelf water into the estuary by Ekman transport. Enhancement of the salt intrusion is comparable between the remote and local winds. Waves decrease the salt intrusion by increasing the water mixing. Sensitivity analysis shows that the axial down-estuary wind, is most efficient in driving increases in salt intrusion via wind straining effect.

Abstract:
Awareness on salt intrusion problem is still lacking in Malaysia due to high precipitation in the region. However, the El-Nino phenomenon that occurred recently has caused extremely low fresh water discharge in the Kuantan River which allowed the sea water to intrude further into its water intake region. Consequently, the Belat River may become potential water resources alternative to build new water intake station for the water supply in the Kuantan River Basin. The aims of this study are to: 1) investigate the salinity distribution in the Belat Estuary; 2) evaluate the applicability of the 1-D analytical salt intrusion solution; 3) determine the calibration parameters in the salt intrusion model. Salt intrusion measurements was conducted during the dry season at spring tide when the fresh water discharge is the minimum. Collection of data such as hydrological data, river cross section and salinity were collected to be used in the salt intrusion analysis. The results obtained show good agreement between the simulated and observed salinity distribution in the estuary with low RMSE and high NSE values. This indicates that the model is reliable and can become an important tool for water manager in conducting salt intrusion study for this area.

Abstract:
Abstract. Intensive measurements of salt intrusion in the Sumjin River estuary were taken at high and low waters during both spring and neap tides in each season from August 2004 to April 2007. The estuary demonstrated partially- and well-mixed characteristics during the spring tide and stratified condition during the neap tide. The salt intrusion at high water varied from about 13.39 km in summer 2005 to 25.62 km in autumn 2006. The salt intrusion depended primarily on the freshwater discharges rather than those of spring-neap tidal oscillations. Analysis of three years of observed salinity data indicated that the salt intrusion length scale in the Sumjin River estuary was proportional to the river discharge to the −1/5 power. Five empirical models were applied to the Sumjin River estuary to explore the most suitable as an easy-to-use tool for prediction of the salt intrusion length as functions of the geometry, river discharge and tide. Comparative results showed that the Nguyen and Savenije (2006) model developed under both partially- and well-mixed estuaries yielded the most satisfactory results of all the models studied for computing the salt intrusion length in the Sumjin River estuary. Our study suggests that the model can generate reasonable results for stratified conditions also.

Abstract:
The purpose of this study was to determine the change in water surface elevation and chloride concentration in the surficial, Mid Hawthorn, and Lower Hawthorn aquifers in the Cape Coral peninsula between 1980 and 1999. Seawater intrusion is a major concern in the Cape Coral area because the city is surrounded by open bodies of saline or brackish waters: Matlacha Pass to the west, San Carlos Bay to the south and Caloosahatchee River to the east. Prior to 1980, the principal groundwater withdrawals were from the Mid Hawthorn aquifer, with some smaller withdrawals from the surficial and Lower Hawthorn aquifers. Since 1980, many wells in the City of Cape Coral have been plugged and capped, decreasing the movement of water between the aquifers. In addition, withdrawals have primarily shifted to the Lower Hawthorn, which is now the principal water supply for the City of Cape Coral. Between 1980 and 1999 the water surface elevation in the surficial aquifer has remained relatively stable and chloride concentrations have decreased. During the same period, chloride concentrations have remained stable within the Mid Hawthorn aquifer. However, the potentiometric surface of the Mid and Lower Hawthorn has decreased and the chloride concentrations in the Lower Hawthorn in the vicinity of the City's wellfield have increased as a direct result of increased withdrawals. In addition, the area of highest chloride concentration within the City has moved west from its historic location, toward the City's reverse osmosis plant. The facility is roughly at the center of the wellfield that supplies water to the plant from the Lower Hawthorn. The potentiometric surface of the Mid Hawthorn has also decreased in the outlying areas of the Cape, mostly to the south and east, due to downward seepage into the Lower Hawthorn and well field pumping to the south in Ft. Myers, and east of Cape Coral along US 41.

Abstract:
Throughout the world, pressures on water resources are increasing, mainly as a result of human activity. Because of their accessibility, groundwater and surface water are the most used reservoirs. The evaluation of the water quality requires the identification of the interconnections among the water reservoirs, natural landscape features, human activities and aquatic health. This study focuses on the estimation of the water pollution linked to two different environmental issues: salt water intrusion and acid mine drainage related to the exploitation of natural resources. Effects of salt water intrusion occurring in the shallow aquifer north of Ravenna (Italy) was analysed through the study of ion- exchange occurring in the area and its variance throughout the year, applying a depth-specific sampling method. In the study area were identified ion exchange, calcite and dolomite precipitation, and gypsum dissolution and sulphate reduction as the main processes controlling the groundwater composition. High concentrations of arsenic detected only at specific depth indicate its connexion with the organic matter. Acid mine drainage effects related to the tin extraction in the Bolivian Altiplano was studied, on water and sediment matrix. Water contamination results strictly dependent on the seasonal variation, on pH and redox conditions. During the dry season the strong evaporation and scarce water flow lead to low pH values, high concentrations of heavy metals in surface waters and precipitation of secondary minerals along the river, which could be released in oxidizing conditions as demonstrated through the sequential extraction analysis. The increase of the water flow during the wet season lead to an increase of pH values and a decrease in heavy metal concentrations, due to dilution effect and, as e.g. for the iron, to precipitation.

Abstract:
Fluctuations in temperature and precipitation amounts due to climate change influence recharge rate of groundwater. Any variations in the amount of precipitation recharge and artificial discharge directly affect groundwater level and so the salt water intrusion rate in the aquifers, which are in contact with sea water. The purpose of this study is to determine the overall historical precipitation recharge trend in Selç
uk sub-basin and to detect whether there is a decrease or increase in recharge amounts due to climate change since 1100 BC. Besides, it covers assessing the future position of the salt water-fresh groundwater interface as a result of possible fluctuations in climate and artificial discharge. For this purpose, numerical density dependent cross sectional groundwater flow with solute transport model was conducted using finite element approach. At first, current salt water-fresh water interface and artificial discharge related head changes in the aquifer were determined. Backward modeling was utilized to obtain concentration distribution in the year 1976 representing the last stage of the undisturbed period. Then, progradation of salt water-fresh water interface since 1100 BC to 1976 was modeled using calibrated parameters and current recharge value. As a result of sea-regression model simulations (1100 BC-1976) less degree of salt water intrusion than that of currently detected in the area was obtained. The result suggests that overall recharge amount in the last 3076 years must have been less than that of 1976. Moreover, future (2010-2099) position of the interface and head changes under the influence of both climate change and increasing water demand were determined. Future model simulations indicate that salt water-fresh water interface moves farther landward. However this movement is mostly due to increasing discharge amount rather than that of climatic changes.

Abstract:
A quantitative understanding of ground water flow characteristics in unconfined aquifers is important because of the prevalence of abstraction from, and pollution of these systems. The current understanding of ground water flow in unconfined aquifers is limited because of the dominance of horizontal flow modelling strategies used to represent unconfined flow processes. The application of horizontal flow principles leads to an ignorance of seepage-face formation and can not predict the complicated three-dimensional nature of the ground water flow that dominates at the ground water-surface water interface. This study aims to address some of these deficiencies by exploring the true three-dimensional nature of ground water flow including the formation of seepage faces at the ground water-surface water interface using numerical and laboratory techniques. A finite element model for simulating two-dimensional (vertical) variably saturated flow is developed and benchmarked against standard laboratory and field-scale solutions. The numerical features of the finite element model are explored and compared to a simple finite difference formulation. The comparison demonstrates how finite element formulations lead to a broader spatial averaging of material properties and a different method for the representation of specified flux boundaries. A detailed comparison analysis indicates that these differences in the finite element solution lead to an improved approximation to the partial differential equation governing two-dimensional (vertical) variably saturated flow. A laboratory analysis of unconfined ground water flow and associated solute transport characteristics was performed. The analysis focused upon unconfined flow towards a pumping well. The laboratory observations were reliably reproduced using a three-dimensional (axi-symmetric), variably saturated ground water flow model. The model was benchmarked against the ground water flow characteristics such as the seepage-face height and total flow rate. In addition, the model was shown to reliably reproduce the solute transport features such as travel times and streamline distributions. This is the first time that a numerical model has been used to reliably reproduce the solute transport characteristics near a seepage-face boundary where the three-dimensional flow effects are prevalent. The ability to reliably predict solute transport patterns in the seepage-face zone is important since this region is known to support vital microbially facilitated reactions that control nutrient cycling and contaminant attenuation. The three-dimensional travel time distribution near the seepage-face was compared to that predicted using a horizontal flow modelling approach derived from the basic Dupuit-Forchheimer equations. The Dupuit-Forchheimer based model indicated that horizontal flow modelling would under-estimate the total residence time near a seepage-face boundary, thereby introducing a considerable source of error in a solute transport analysis. For this analysis, a new analytical solution for the steady travel time distribution in an unconfined aquifer subject to a single pumping well was derived. The analytical model has identified, for the first time in the hydrogeology literature, the use of the imaginary error function. The imaginary error function is a standard transcendental function and an infinite series approach to evaluate the function was successfully proposed. The two-dimensional (vertical) ground water flow model was extended to handle the case where the flow is driven by density gradients near the ground water-surface water interface. The unsteady, two-dimensional, Galerkin finite element model of density-dependent ground water flow in variably saturated porous media is rigorously presented and partially benchmarked under fully saturated (confined) conditions. The partial benchmarking involved reproducing solutions to the standard Henry salt-water intrusion and the Elder salt-convection problems. The model was used in a standard density-coupled and a new density-uncoupled mode to elucidate the worthiness of the Henry and Elder problems as benchmark standards. A comparison of the coupled and uncoupled solutions indicates that the Henry salt-water intrusion problem has limited worthiness as a benchmark as the patterns of ground water flow are relatively insensitive to density-coupled effects. Alternatively, the Elder problem is completely dependent upon a correct representation of the density-coupled flow and solute transport processes. The coupled versus uncoupled comparison is proposed as a new test of the worthiness of benchmark standards. The Henry salt-water intrusion problem was further analysed in an attempt to alleviate some of the difficulties associated with this benchmark problem. The numerical model was tested against a re-evaluated version of Henry's semi-analytical solution for the coupled solute concentration distribution. The numerical model was used to propose a modified version of the Henry problem where the importance of density-coupled processes was increased. The modified problem was shown to have an improved worthiness as compared to the standard solution. The numerical model results were benchmarked against a new set of semi-analytical results for the modified problem. Certain advantages in using the modified problem as a test case for benchmarking the results of a numerical model of density-dependent ground water flow are identified. A numerical investigation of the patterns of density-driven ground water flow at the ground water-surface water interface was undertaken. The numerical model is shown to produce grid-independent results for a finely discretised domain. The pattern of discharge is controlled, in part, by two parameters. One describes the recharge applied to the aquifer, and the second describes the magnitude of the density differences between the fresh recharging fluid and the saline receiving fluid. The influence of dense intrusions upon the formation of seepage-face boundaries at the ground water-surface water interface under steady-state conditions was also investigated. Dense intrusions are shown to dominate the pattern of ground water flow only under mild recharge conditions, while seepage faces dominate the outflow pattern under strong recharge conditions. Therefore, the formation of seepage-face boundaries and dense intrusions are unlikely to coincide under the conditions examined in this study.

Abstract:
L'étude des milieux hétérogènes carbonatés et karstifiés trouve aujourd'hui de nombreuses applications dans les problématiques environnementales, comme la description fine de la structure d'un réservoir côtier, support d'un aquifère affecté par une intrusion d'eau salée. Au sud de l'ile de Majorque (Baléares, Espagne), la plate-forme carbonatée de Llucmajor représente un site privilégié pour ce type d'étude.La caractérisation des hétérogénéités ne peut être réalisée sans une description préalable des propriétés des réservoirs carbonatés et des facteurs modifiant la structure du réservoir. Un des paramètres clés définissant la structure hétérogène est la porosité. Au regard de la large gamme de tailles d'hétérogénéités allant du micromètre à la centaine de mètre, l'utilisation de méthodes multi-échelles est nécessaire.Ce travail de thèse a porté sur la détermination multi-échelles de la porosité, allant de la microporosité à la porosité karstique, et l'établissement de relations entre les changements d'échelles d'observation de ces propriétés. Dans un premier temps, l'application de la microtomographie à rayons X extrait la microporosité et la connectivité des réseaux microporeux. Puis, la tomographie a été utilisée avec une résolution plus faible afin d'étudier le réseau micro- et macroporeux à l'échelle de la carotte. A l'échelle du puits, les images de paroi de puits permettent de déterminer la porosité allant des macropores centimétriques aux karsts. Enfin, la géophysique de surface a permis d'observer l'extension des karsts et hétérogénéités dans une grande partie du site.Ainsi, la structure poreuse du site étudié a été intégrée dans la géologie régionale de la plate-forme. L'observatoire installé sur le site pour surveiller la propagation de l'eau salée dans l'aquifère peut être replacé dans son contexte géologique et pétrophysique, afin d'affiner l'interprétation de ses mesures de variations de salinité
The study of heterogeneous and karstified carbonates is important in many environmental issues, like the detailed description of a coastal reservoir structure containing an aquifer affected by saline intrusion. At the south of the island of Mallorca (Spain), the Llucmajor carbonate platform represents a typical site for such researches. Characterization of heterogeneities requires a better knowledge of the carbonate reservoir properties and the various factors affecting the structure. One of the key parameters defining the heterogeneous structure is the porosity. According to the wide range of heterogeneity sizes from micrometer to hundreds of meters, the use of multiscale methods is required.This thesis focused on the determination of multiscale porosities from the microporosity to karstic porosity, and of relationships between observation scale changes of these properties. Firstly, the application of X-ray microtomography allows to extract the microporosity and the microporous network connectivity. Then, X-ray tomography was used with a lower resolution to study the micro- and macro-porous network at the core scale. At the borehole scale, the borehole wall images are used to determinate macrostructures from centimeter pores to karsts. Finally, surface geophysics allows to observe the extension of karst and heterogeneities at the site scale.Finally, the porous structure of the study site is integrated into the regional geology of the platform. A hydrogeophysical observatory was installed on site to monitor the spreading of salt water in the aquifer. The interpretation of its salinity measurements can take into account the geological and petrophysical context

Abstract:
Gotland suffers from a shortage of drinking water at infrequent intervals which is onlypredicted to get worse with time. The problem is not a shortage of precipitation, the shortagelies in the combined problem of runoff and high water usage during the summer months.From September to March there is an abundance of water which mostly goes to runoff intothe sea surrounding Gotland. Due to the fact that Gotland is an island, a concave boundryis formed between the deeper saline groundwater and the fresh groundwater closer to thesurface. In an effort to possibly help in solving the water shortage, an idea was introducedto pump out the saline groundwater from the deep and thus creating an increase in storageof fresh groundwater.Firstly an investigation into suitable locations for modeling was conducted where two siteswere chosen. To test this concept and see if the idea was feasable a 2D-model was establishedusing GMS, MODFLOW, MT3DMS and SEAWAT with the aim of simulating the groundwaterat the well chosen sites on Sudret, Gotland. Two wells were implemented in the model,one for extracting fresh groundwater and one for extracting saline groundwater. The hopeswere to be able to simulate an increase of the storage of fresh water during the rechargeperiod and thus helping to solve the problem with insufficient water during the strenuoussummer months. Hopefully the results of the simultations can make up the foundations foran implementation of the concept at a location at Gotland.Results for site 1 indicate that the volume of fresh water in the akvifer can be increasedby 13of the extraction volume when only saline groundwater is removed. The maximumflow of only saline extraction at site 1 has been determined to 35m3år per meter. For example,with only an extraction of saline water of 35m3år at site 1 the fresh water in the aquifer willincrease by 340m3 per metre after 10 years.The model indicates that the volume of fresh water in the akvifer can be increased bya minimum of 15 of the saline extraction volume when only saline water is removed. Themaximum flow of only saline groundwater at site 2 was decided to be 65m3år per meter. Forexample, with only an extraction of saline water of 65m3år at site 1 the fresh water in theakvifer will increase by 940m3 per metre after 10 years.
Gotland lider till och från av vattenbrist under sommaren, problemen förväntas även ökai samband med klimatförändringar och expanderande antropogen påverkan. Under vinterhalvåretfår Gotland mer än tillräckligt med sötvatten för att täcka efterfrågan, problemetuppkommer från att majoriteten av vattnet evapotranspireras samt går till ytavrinning tillÖstersjön. Ytterligare en orsak till vattenbristen beror på att Gotlands grundvatten omgesav saltvatten. Saltvattnet kring Gotland bildar en konkav gräns mellan sött och salt vatten igrundvattenmagasinet vilket väsentligt begränsar den möjliga lagringen av sött grundvatten.För att hjälpa till att lösa problemen med vattenbrist på Gotland introducerades en idé attutöka andelen sött vatten i grundvattenmgasinen genom att pumpa salt grundvatten fråndjupet under återhämtningsperioden.Arbetet påbörjades genom att undersöka en lämplig plats på Gotland, både ur en modelleringssynpunktsamt inför ett eventuellt fortsatt arbete. Två platser valdes slutligen dären 2D-grundvattenmodell skapades vid båda platserna med hjälp av GMS, MODFLOW,MT3DMS och SEAWAT. I modellen implementerades två uttagsbrunnar, en för salt grundvattenfrån djupet och en för sött grundvatten närmare ytan. Eftersom modellen skapats i 2Dinnebär det det en förenkling av geometrin och modellresultat motsvarar då en horisontelltborrad brunn, därför anges resultaten som flöde per meter horisontell brunn. Förhoppningenvar att genom simulering kunna påvisa en ökning av sötvatten i grundvattenmagasinet genomatt extrahera salt grundvatten under återhämtningsperioden. målet är att undersökningarnaska leda till en implementering av metoden i verkligheten i ett försök att minska vattenbristen.Modellresultat för plats 1 indikerar att volymen sött vatten i akviferen ökar med 13 avuttaget när endast salt vatten extraheras. Det maximala uttagsflödet vid plats 1 för endastsalt vatten bestämdes till 35m3år per meter. Vid ett saltvattenuttag på 35m3år vid plats 1 ökarsötvattenvolyem i akviferen t.ex. med 340m3 per meter efter 10 år.Modellresultat för plats 2 indikerar att volymen sött vatten i akviferen ökar med 15 avuttaget när endast salt vatten extraheras. Det maximala uttagsflödet vid plats 2 för endastsalt vatten bestämdes till 65m3år per meter. Vid ett saltvattenuttag på 65m3år vid plats 2 ökarsötvattenvolyem i akviferen t.ex. med 940m3 per meter efter 10 år.

Abstract:
Lieu de développement économique et démographique intense, les zones littorales font l'objet de pressions importantes sur l'environnement et, en particulier, sur les ressources en eau. Bien que la gestion des eaux souterraines côtières bénéficie de nombreux résultats issus de la recherche scientifique, une des problématiques majeures reste la connaissance de la géométrie des aquifères. Des interprétations géologiques de la genèse du bassin Plio-Quaternaire du Roussillon, issues de la stratigraphie séquentielle, sont confrontées, par l'intermédiaire d'une base données, à l'hydrogéologie de cet hydrosystème complexe localisé sur la partie littorale des Pyrénées-Orientales. L'étude statistique des points de prélèvement (distribution des crépines, productivité des forages...), l'analyse fonctionnelle (traitement du signal des chroniques piézométriques), l'hydrochimie et la géophysique électrique ont été utilisées afin d'élaborer un modèle conceptuel hydrogéologique des écoulements à l'échelle du bassin et de son prolongement vers le domaine offshore. La présence de la mer, de zones à salinité résiduelle et de cours d'eaux littoraux contribue à augmenter la salinité d'un aquifère libre supérieur (Quaternaire) sus-jacent aux différents aquifères captifs (Pliocène) exploités pour l'eau potable dans la zone littorale. La vulnérabilité face aux intrusions salines de cette ressource de bonne qualité, tant sur le point de vue quantitatif que qualitatif est appréhendée par modélisation. Dans le domaine offshore, le rôle protecteur des formations géologiques à faible et moyenne perméabilité est mis en évidence vis-à-vis de la préservation de la qualité de l'eau potable.

Abstract:
The anisotropy of the Biscayne Aquifer which serves as the source of potable water for Miami-Dade County was investigated by applying geophysical methods. Electrical resistivity imaging, self potential and ground penetration radar techniques were employed in both regional and site specific studies. In the regional study, electrical anisotropy and resistivity variation with depth were investigated with azimuthal square array measurements at 13 sites. The observed coefficient of electrical anisotropy ranged from 1.01 to 1.36. The general direction of measured anisotropy is uniform for most sites and trends W-E or SE-NW irrespective of depth. Measured electrical properties were used to estimate anisotropic component of the secondary porosity and hydraulic anisotropy which ranged from 1 to 11% and 1.18 to 2.83 respectively. 1-D sounding analysis was used to models the variation of formation resistivity with depth. Resistivities decreased from NW (close to the margins of the everglades) to SE on the shores of Biscayne Bay. Porosity calculated from Archie's law, ranged from 18 to 61% with higher values found along the ridge. Higher anisotropy, porosities and hydraulic conductivities were on the Atlantic Coastal Ridge and lower values at low lying areas west of the ridge. The cause of higher anisotropy and porosity is attributed to higher dissolution rates of the oolitic facies of the Miami Formation composing the ridge. The direction of minimum resistivity from this study is similar to the predevelopment groundwater flow direction indicated in published modeling studies. Detailed investigations were carried out to evaluate higher anisotropy at West Perrine Park located on the ridge and Snapper Creek Municipal well field where the anisotropy trend changes with depth. The higher anisotropy is attributed to the presence of solution cavities oriented in the E-SE direction on the ridge. Similarly, the change in hydraulic anisotropy at the well field might be related to solution cavities, the surface canal and groundwater extraction wells.
