Reactive transport modeling is an important tool for the analysis of physical, chemical and biological processes encountered in many environmental systems. Several upscaled models, of natural or engineered porous media, are commonly used for such modeling and take advantage of standard advection dispersion reaction equations (ADREs). These simple models are however unable to account for physical processes that can heavily influence reactive transport in such media, such as pre-asymptotic flow fields and mixing limitations between transport and reaction processes. To account for these complexities, researchers have developed proportionally complex mathematical and simulation-based models. However, these complicated models have remained underutilized among most practitioners owing to their non-intuitive formulations and computationally intensive mathematics. In this thesis, we present a novel, intuitive and relatively less strenuous computational method for the simulation of homogenous chemical reactions through the use of age: defined as exposure-time to the flow field, structured ADREs.The utility of this method is demonstrated through the development of two models to quantify mixing processes and pre-asymptotic dispersion without the use of non-local models. Analysis of reactive transport in porous media has benefited from the concept of mixing ratios, in particular as a basis for mathematical separation of different species and processes. Additionally, general use of solute age has been recently explored as a proxy for reaction extent. Pairing these two concepts we developed mixing ratio models, structured on age, that is cast into a 1D transport formulation and compared with conventional formulations of mixing ratio models. This modeling framework was applied to the problem of mixing-limited reactive transport in one-dimension by explicitly considering unmixed and mixed phases. To address mixing limitations under the entirety of transport, including the pre-asymptotic dispersion timeframe, I use age-dependent dispersion coefficient in a local-formulation of transport. This formulation addresses the divisive controversy surrounding the use of time-dependent dispersion coefficients within an ADRE framework. Our physically intuitive model matches the performance of a recently published complicated and computationally intensive model of transient dispersion in direct comparison. Furthermore, our solutions can be applied to other upscaled one-dimensional transport problems such as river corridor, pipe networks, groundwater flows.

Using isotopes as a tool for understanding Earth processes From establishing the absolute age of the Earth to providing a stronger understanding of the nexus between geology and life, the careful measurement and quantitative interpretation of minor variations in the isotopic composition of Earth’s materials has provided profound insight into the origins and workings of our planet. Isotopic Constraints on Earth System Processes presents examples of the application of numerous different isotope systems to address a wide range of topical problems in Earth system science. Volume highlights include: examination of the natural fractionation of non-traditional stable isotopes utilizing isotopes to understand the origin of magmas and evolution of volcanic systems application of isotopes to interrogate and understand Earth’s Carbon and Oxygen cycles examination of the geochemical and hydrologic processes that lead to isotopic fractionation application of isotopic reactive transport models to decipher hydrologic and biogeochemical processes The American Geophysical Union promotes discovery in Earth and space science for the benefit of humanity. Its publications disseminate scientific knowledge and provide resources for researchers, students, and professionals.

This text combines the science and engineering of hydrogeology in an accessible, innovative style. As well as providing physical descriptions and characterisations of hydrogeological processes, it also sets out the corresponding mathematical equations for groundwater flow and solute/heat transport calculations. And, within this, the methodological and conceptual aspects for flow and contaminant transport modelling are discussed in detail. This comprehensive analysis forms the ideal textbook for graduate and undergraduate students interested in groundwater resources and engineering, and indeed its analyses can apply to researchers and professionals involved in the area.

This book offers readers a comprehensive overview, and an in-depth understanding, of suitable methods for quantifying and characterizing saline aquifers for the geological storage of CO2. It begins with a general overview of the methodology and the processes that take place when CO2 is injected and stored in deep saline-water-containing formations. It subsequently presents mathematical and numerical models used for predicting the consequences of CO2 injection. This book provides descriptions of relevant experimental methods, from laboratory experiments to field scale site characterization and techniques for monitoring spreading of the injected CO2 within the formation. Experiences from a number of important field injection projects are reviewed, as are those from CO2 natural analog sites. Lastly, the book presents relevant risk management methods. Geological storage of CO2 is widely considered to be a key technology capable of substantially reducing the amount of CO2 released into the atmosphere, thereby reducing the negative impacts of such releases on the global climate. Around the world, projects are already in full swing, while others are now being initiated and executed to demonstrate the technology. Deep saline formations are the geological formations considered to hold the highest storage potential, due to their abundance worldwide. To date, however, these formations have been relatively poorly characterized, due to their low economic value. Accordingly, the processes involved in injecting and storing CO2 in such formations still need to be better quantified and methods for characterizing, modeling and monitoring this type of CO2 storage in such formations must be rapidly developed and refined.
