Full textDespite the diversity of the contributions to the analysis of water resources and the myriad of water management experiences, transboundary groundwaters have only relatively recently entered the international political agenda. In line with research dedicated to understanding the challenges associated with the management of water resources and the creation of environmental regulatory frameworks, this dissertation examines the emergence of mechanisms for the management of transboundary groundwater resources. In doing so, it makes a seemingly straightforward inquiry. What are the factors that trigger the emergence and implementation of groundwater management mechanisms? Drawing from the review of the literature and the comparative analysis of three cases of transboundary groundwater management, this research finds that the recognition of groundwater problems is determined by the interplay of three factors: the uses of groundwater, the features of the hydrogeological resources, and the social valuation of the eco-system services provided by the resources. In addition, it suggests that groundwater problems are not sufficient to explain the nature of the mechanisms employed for the management of the resources. It argues that management mechanisms, which may be coordinated or unilateral, result from the configuration of both systemic and socio-institutional factors

Full texts equation which incorporates a nonlinear term. Governing equations are coupled by an interaction term that controls the quasi-steady state fracture-block interflow. Governing equations are solved numerically by the Crank-Nicolson implicit scheme. The numerical results are compared to the analytical results for the same problem which assumes Darcian flow both in fractures and blocks. Numerical and analytical solutions give same results when Reynold&rsquo
s number is less than 0.1. The effect of non-linearity on the flow appears when Reynold&rsquo
s number is greater than 0.1. The larger the piezometric head gradient, the higher the flow rate and, thus, higher the non-linearity is. The effect of aquifer parameters on the flow is also investigated. The proposed model and its numerical solution is a unique application of non-linear flow models to the fractured aquifers. It can be used in predicting water levels in fractured aquifers and evaluating time dependent flow rates in the analysis of recession hydrographs.
Xu, Xiuyuan. "Interaction of Chemical Oxidants with Aquifer Materials." Thesis, University of Waterloo, 2006. http://hdl.handle.net/10012/2891.
Full textThe investigation into the interaction between aquifer materials and permanganate consisted of three series of bench-scale experiments: (1) long-term batch experiments which were used to investigate permanganate consumption in response to fundamental geochemical properties of the aquifer materials, (2) short-term batch experiments which were designed to yield kinetic data that describe the behavior of permanganate in the presence of various aquifer materials, and (3) column experiments which were used to investigate permanganate transport in a system that mimics the subsurface environment. The long-term experiments which involved more than 180 batch reactors monitored for ~300 days showed that the unproductive permanganate consumption by aquifer materials or natural oxidant demand (NOD) is strongly affected by the initial permanganate concentration, permanganate to solid mass ratio, and the reductive components associated with each aquifer material. This consumption cannot be represented by an instantaneous reaction process but is kinetically controlled by at least a fast and slow reactive component. Accordingly, an empirical expression for permanganate NOD in terms of aquifer material properties, and a hypothetical kinetic model consisting of two reaction components were developed. In addition, a fast and economical permanganate NOD estimation procedure based on a permanganate COD test was developed and tested. The investigation into short-term permanganate consumption (time scale of hours) was based on the theoretical derivation of the stoichiometric reaction of permanganate with bulk aquifer material reductive components, and consisted of excess permanganate mass experiments and excess aquifer material mass experiments. The results demonstrated that permanganate consumption by aquifer materials can be characterized by a very fast reaction on the order of minutes to hours, confirming the existence of the fast reaction component of the hypothetical kinetic model used to describe the long-term permanganate NOD observations. A typical experimental column trial consisted of flushing an aquifer-material packed column with the permanganate source solution until sufficient permanganate breakthrough was observed. The permanganate column results indicated the presence of a fast and slow consumption rate consistent with the long-term batch test data, and an intermediate consumption rate affecting the shape of the rising limb of the breakthrough curve. Finally, a comparison of the experimental results between batch and column systems indicated that permanganate NOD was significantly overestimated by the batch experiments; however, permanganate consumption displayed some similarity between the batch and column systems and hence an empirical expression was developed to predict permanganate consumption in physically representative column systems from batch reactor data.
The interaction between hydrogen peroxide and aquifer materials was also investigated with both batch and column experiments. A series of batch experiments consisting of a mixture of 2% hydrogen peroxide and 15 g of aquifer materials was used to capture the overall hydrogen peroxide behavior in the presence of various aquifer materials. The results indicated that the decomposition of hydrogen peroxide in the presence of various aquifer materials followed a first-order rate law, and was strongly affected by the content of amorphous transition metals (i. e. , Fe and Mn). Although hydrogen peroxide decomposition is related to the total organic carbon (TOC) content of natural aquifer materials, the results from a two-week long exposure to hydrogen peroxide suggests that not all forms of natural organic matter contributed to this decomposition. A multiple linear regression analysis was used to generate predictive relationships to estimate hydrogen peroxide decomposition rate coefficients based on various aquifer material properties. The enhanced stability of hydrogen peroxide was investigated under six scenarios with the addition of chelating reagents. The impact of a new green chelating reagent, S,S'-ethylenediaminedisuccinate (EDDS), on the stability of hydrogen peroxide in the presence of aquifer materials was experimentally examined and compared to that of the traditional and widely used chelating reagent, Ethylenediaminetetraacetic (EDTA). The results demonstrated that EDDS was able to significantly increase the stability of hydrogen peroxide, especially for aquifer materials with low TOC contents and/or high dissolvable Fe and Mn contents. Finally, to complement and expand the findings from the batch experiments, column experiments were conducted with aquifer materials from five representative sites. Each column was flushed with two types of source solutions (with or without EDDS addition) at two flow rates. The column experiments showed that the use of EDDS resulted in an earlier breakthrough and a higher stable concentration of hydrogen peroxide relative to the case without the addition of EDDS. The hydrogen peroxide decomposition rate coefficients generated from the column data were significantly higher than those generated from the batch test data and no correlation between hydrogen peroxide decomposition coefficients obtained from column and batch experiments was observed. Based on the column experimental results, a one-dimensional transport model was also calibrated to capture the hydrogen peroxide breakthrough process.
Data from bench-scale tests are routinely used to support both ISCO design and site screening, and therefore the findings from this study can be used as guidance on the utility of these tests to generate reliable and useful information. In general, the behavior of both permanganate and hydrogen peroxide in the presence of aquifer materials in batch and the column systems clearly indicates that the use of batch test data for ISCO system design is questionable since column experiments are believed to mimic in situ conditions better since column systems provide more realistic aquifer material contact. Thus the scaling relationships developed in this study provide meaningful tools to transfer information obtained from batch systems, which are widely employed in most bench-scale studies, to column systems.

Full textEsta tese apresenta os resultados dos estudos geológicos, hidrogeológicos, hidroquímicos, das fontes de poluição e do cadastramento de fontes de água subterrânea da área correspondente à bacia hidrográfica do rio Urussanga, Estado de Santa Catarina. A Bacia do Rio Urussanga apresenta uma rede de drenagem de 1064 km de extensão, abrangendo uma área de 580 km² com densidade média de drenagem de 1,83 (km/km2), e é formada pela junção dos rios Carvão e Maior. e outros tributários, destacando-se os seguintes rios: América, Caeté, Vermelho, Cocal, Ronco D´Água, Três Ribeirões, Cocalzinho, Ribeirão da Areia, entre outros. No mapeamento hidrogeológico foram identificados 11 sistemas aqüíferos, sendo 4 relacionados às rochas sedimentares gonduânicas, 1 aos sedimentos quaternários pleistocênicos, 1 relacionado às rochas basálticas cretáceas, 4 relacionados as formações sedimentares paleozóicas e um relacionado aos granitos neoproterozóicos. As atividades de mineração e de beneficiamento do carvão, as atividades industriais, a falta de rede de canalização e de tratamento de esgoto em todos os municípios e a utilização de adubos e defensivos agrícolas nas áreas cultivadas estão entre os principais fatores responsáveis pela contaminação dos recursos hídricos, degradação do solo e, conseqüentemente, pelo comprometimento ambiental de grande parte da área desta bacia hidrográfica.
This work presents the results regarding the geological, hydrogeological and hydrochemical surveys carried out in the area of Urussanga Hydrographic Basin. It also shows the data related to the pollution sources and the number of groundwater explotation spots in the referred basin. The Urussanga Hydrographic Basin has na drainage extension of 1064 km , covering 580 km² in área with a average drainage density of 1,83 (km/km2).It is formed by the junction of the rivers Carvão and Maior. Other trybutaries are also important: América, Caeté, Vermelho, Cocal, Ronco D´Água, Três Ribeirões, Cocalzinho, Ribeirão da Areia, between others little more. Regarding the structural aspects, we have concluded that the most important elements are the faults. The results off physic-chemical analysis of groundwater carried out along this study and in previous works have given us the hydrochemical classification of the different aquifer systems present in this basin.. Coal mining and treatment activities as well as industrial activities, the lack of drainage, the use of fertilizers and pesticides in the crops are the main responsible factors for water ressources contamination and soil degradation in this area. As a consequence, a large portion of the Urussanga Hydrographic Basin is in a bad environmental situation.

Full textThe study addressed the groundwater assessment and sustainable management of the coastal alluvial aquifers in Namib Desert, the Omaruru River Delta Aquifer (Omdel Aquifer) was used as a case study. Sustainable utilization of groundwater in parts of hyper-arid Sub-Saharan Africa, like the Namib Desert, is always a challenge due to lack of resources and data. Understanding of hydrogeological characteristics of the Omaruru Delta Aquifer System is a pre-requisite for the management of groundwater supply in the Central Namib area (Namib Desert). For the Omdel Aquifer in the Omaruru catchment, Namibia, issues to investigate include the lack of information on the geology and hydrogeological setting, the hydraulic properties and geometry of the aquifer at the inflow and outflow sections, groundwater recharge conditions upstream of the aquifer, and the impact of artificial recharge.

Full textEnsayos en campo, incluyendo diferentes tipos de cultivo y prácticas agrícolas, son llevados a cabo en al área del Campo de Cartagena, sureste de España, una región semi-árida donde la agricultura intensiva es el principal uso de suelo. El desarrollo de metodologías con observaciones en el medio saturado y no saturado, junto con la modelación numérica, fueron usados para mejorar la compresión de los procesos que controlan la recarga a partir de zonas intensamente regadas. Las aproximaciones desarrolladas pueden ser resumidas como sigue:
Ensayo de campo a lo largo de seiscientos días bajo cultivos hortícolas anuales y riego por goteo. La distribución del contenido de agua en la zona de raíces y bajo esta fue simulada considerando un modelo de flujo no saturado. El contenido de agua y la succión fueron medidos a diferentes profundidades y empleados para la calibración y validación del modelo.
Ensayo de trazador (tritio) en campo en una parcela experimental con riego por goteo y cultivos hortícolas anuales durante cuatrocientos treinta días. El movimiento de trazador a lo largo del perfil de suelo fue simulado considerando transporte multifásico. Los perfiles de concentración de trazador, a partir de un espaciado y limitado número de muestras destructivas, fueron usados para calibrar y validar el modelo.
Experimento de larga duración (nueve años hidrológicos) para diferentes tipos de cultivo: cultivos hortícolas anuales, cultivos hortícolas perennes y árboles frutales. La recarga producida por cada tipo de cultivo fue estimada a partir del balance de agua en suelo, zona no saturada y acuífero. Las fluctuaciones del nivel freático registradas a lo largo del mencionado periodo fueron usadas para calibrar y validar el modelo. Esta experiencia permitió evaluar la fiabilidad de las estimaciones de recarga a partir de las otras dos metodologías previas (a corto plazo) para el tipo de cultivo coincidente (cultivos hortícolas anuales).
Para las tres aproximaciones, el cubrimiento de suelo por las plantas y el crecimiento de raíces han sido incluidos en la condición de contorno superior. La evapotranspiración se ha dividido en evaporación y transpiración como una función del índice de área de hoja, y es limitada por el contenido de agua en el suelo. La transpiración a su vez ha sido distribuida a través del perfil de suelo como una función del contenido de agua y profundidad de raíces.
Valores similares de recarga han sido obtenidos a partir de las tres técnicas, aunque el modelo de flujo no saturado la sobreestima ligeramente. La evapotranspiración real fue siempre más baja que la potencial, ya que el contenido de agua en suelo fue insuficiente para mantener la extracción de agua por parte de las raíces, a pesar de la alta frecuencia de riego. Aunque las prácticas agrícolas por parte de los agricultores son las correctas, con una alta eficiencia de riego, se obtuvieron altos valores de recarga. La lluvia es distribuida de manera irregular en unos pocos eventos intensivos, algo por otro lado muy común en regiones semi-áridas, lo que contribuye de manera significativa a la percolación profunda, debido al constante alto contenido de humedad en el suelo.
In the past decades a large body of literature has focused on the assessment of the natural recharge and parameters of control (including climate, vegetation, soils, and topography). On the contrary, only few papers focused on aquifer recharge from intensively irrigated farmland. Although findings have improved the understanding of recharge phenomena, they still fail to characterize many features of aquifer recharge from the mentioned land use. In this context, the aims of this thesis are: (i) to improve the understanding of aquifer recharge from intensively irrigated farmland, and (ii) to provide new tools for its characterization. Also, this thesis provides a framework that can be easily used by practitioners to infer quantitative information.
Field tests, including different crop types and agricultural management, were carried out in the Campo de Cartagena area of southeast Spain, a semi-arid region where intensive irrigated agriculture is prevalent. The development of methodologies, with field observations in both saturated and unsaturated media, along with the application of numerical modelling were used to understand the processes governing the recharge from irrigated farmland. The developed approaches can be summarized as follows:
A field experiment with annual row crops and drip irrigation. Soil moisture dynamics through the root zone and below were simulated from unsaturated flow approach. Soil moisture and pressure head data at different depths were recorded along six hundred days for model calibration and prediction.
A tracer test (tritium) in field along four hundred thirty days. The test was carried out in an experimental plot with drip irrigation and annual row crops. The tracer transport in soil was simulated considering a multiphase approach. Tracer concentration profiles, from a limited and sparse number of destructive samples, were used to calibrate and validate the modelling approach.
A long-term field experiment (based on nine hydrologic years) for different crop types, annual row crops, perennial vegetables and fruit trees. The recharge produced from each crop type was estimated from a water balance approach, including soil, vadose zone and aquifer. Water table fluctuations, recorded along the mentioned period, were used for model calibration and predictions. This long-term approach permits to evaluate recharge estimates reliability of the two previous methodologies (short-term) for the type of crop overlapped (annual row crops).
For the three approaches, ground cover and root depth are assumed as upper boundary conditions. Evapotranspiration is allocated to evaporation and transpiration as a function of leaf-area-index and is limited by soil moisture content; transpiration is distributed through the soil profile as a function of soil moisture and root depth.
Similar recharge values have been obtained from the three techniques, although the unsaturated flow approach slightly overestimates values. Actual evapotranspiration was always lower than potential evapotranspiration, because soil moisture was insufficient to sustain the potential uptake, despite high irrigation frequency. Although the agricultural practices from farmers are sound, high irrigation efficiency, high recharge values are achieved. Rainfall is unevenly distributed into a few intensive events, likewise very common in semi-arid regions, and it meaningfully contributes to deep percolation, due to consistently high soil water content.

Full textbudgets, (2) to assess the potential impacts of upstream reservoirs on lake levels, and (3) to determine effects of potential climatic change on lakes and groundwater levels in the basin. Available data have been used to develop a conceptual model of the system. The three dimensional groundwater model (MODFLOW) has been developed for the system. The model has been calibrated successfully under transient conditions over a period of six years using monthly periods. The results show that groundwater inflows and outflows have the lowest contribution to the overall lakes&rsquo
budget. A sensitivity analysis was conducted to determine the limits within which the regional parameters may vary. Three groundwater management scenarios had been developed. The results show that the upstream reservoirs have a significant effect on lake stages but not on groundwater levels. A trade-off curve between the amount of water released and the average stage in Lake Mogan has been developed. The continuation of the existing average conditions shows that there would be declines in groundwater elevations in areas upstream from Lake Mogan and downstream from Lake Eymir. The results also indicated that very small, but long-term changes to precipitation and temperature have the potential to cause significant declines in groundwater and lake levels.
