    Abstract: This book provides an overview of facts, theories and methods from hydrology, geology, geophysics, law, ethics, economics, ecology, engineering, sociology, diplomacy and many other disciplines with relevance for concepts and practice of water resources management. It provides comprehensive, but also critical reading material for all communities involved in the ongoing water discourses and debates. The book refers to case studies in the form of boxes, sections, or as entire chapters. They illustrate success stories, but also lessons to be remembered, to avoid repeating the same mistakes. Based on consolidated state-of-the-art knowledge, it has been conceived and written to attract a multidisciplinary audience. The aim of this handbook is to facilitate understanding between the participants of the international water discourse and multi-level decision making processes. Knowing more about water, but also about concepts, methods and aspirations of different professional, disciplinary communities and stakeholders professionalizes the debate and enhances the decision making.

    Description / Table of Contents: The E-Book "River Basins and Change" was launched at the 6th World Water Forum at Marseille. The book is a joint endavour of GWSP and UNESCO-IHE. This electronic book contains the major contributions to the international conference „Global Dimensions of Change in River Basins. Threats, Links and Adaptation“ organised by the Global Catchment Initiative (GCI) of GWSP in Bonn, Germany in December 2010. Addressing especially graduate students and young professionals in the field of freshwater research, the book is meant as an introduction to the issues, debates and contributions of the conference. It is structured into three sections: 1. Global Change and River Basins, 2. Accounting for Water and River Basins, 3. Governance and River Basins. The book is devised as a free publication in digital form to achieve maximum outreach and accessability.

    Description: Cyclic microfracturing and epitaxial crystal growth have long been recognized in crack‐seal veins, but an understanding of a single crack‐seal cycle is still missing. Here we present a phase‐field model that includes both fracture mechanics of crack propagation, and epitaxial crystal growth on the fracture walls, repeating this cycle multiple times in a polycrystalline, microporous quartz rock. Our simulations have two end members: If a vein completely seals, it is stronger than the host rock, cracking is delocalized, forming many single‐seal microveins. Incomplete sealing makes the vein weaker than the host rock and localizes the new fracture inside the vein, leading to multi‐crack‐seal. We suggest that the sealing degree is a key parameter in hydrothermal systems and multi‐crack‐seal veins are long‐lived, microporous sites of mechanical weakness. We generalize the phase‐field approach to conduct probabilistic simulations in between these two types, and show how systems of microveins and multi‐crack‐seal veins emerge.
    Description: Plain Language Summary: Fluids in the Earth's crust can alter permeability and porosity, precipitate and dissolve minerals, transport material and interact with deformation. This affects the transport and mechanical properties of the rock system and in turn has consequences for example, in subsurface engineering applications. In this work we simulate the processes of fracturing and crystal growth on grain scale in a microporous rock structure and show how different crystal structures form. The basic steps of a crack‐seal process and how fracturing and sealing interact are explored. Our results show that if a fracture completely seals a new crack will form in the host rock and many thin microveins form. In contrast, an incomplete sealing makes the vein weaker than the host rock and leads to a new cracking inside the vein, which enlarges the existing structure with each cycle. This implies that the degree of sealing is the cause of this division, where crack‐seal veins are microporous sites of mechanical weakness. Additionally, we perform probabilistic simulations which show how many single‐seal microveins form side‐by‐side with a few multi‐crack‐seal veins. Our studies provide valuable insight in structure‐property linkages and enable a better prediction of fracture‐sealing.
    Description: Key Points: Systematic phase‐field study captures elementary steps of the crack‐seal process at grain scale. Incomplete sealing makes a vein weaker than the host rock and localizes a new fracture inside the vein which leads to multi‐crack‐seal. Probabilistic simulations show how systems of many microveins and a few thick crack‐seal veins form side by side.

    Description: 〈title xmlns:mml="http://www.w3.org/1998/Math/MathML"〉Abstract〈/title〉〈p xmlns:mml="http://www.w3.org/1998/Math/MathML" xml:lang="en"〉Fluid flow in fracture porosity in the Earth's crust is in general accompanied by crystallization or dissolution depending on the state of saturation. The evolution of the microstructure in turn affects the transport and mechanical properties of the rock, but the understanding of this coupled system is incomplete. Here, we aim to simulate spatio‐temporal observations of laboratory experiments at the grain scale (using potash alumn), where crystals grow in a fracture during reactive flow, and show a varying growth rate along the fracture due to saturation differences. We use a multiphase‐field modeling approach, where reactive fluid flow and crystal growth is computed and couple the chemical driving force for grain growth to the local saturation state of the fluid. The supersaturation of the fluid is characterized by a concentration field which is advected by fluid flow and in turn affects the crystal growth with anisotropic growth kinetics. The simulations exhibit good agreement with the experimental results, providing the basis for upscaling our results to larger scale computations of combined multi‐physical processes in fractured porous media for applications as groundwater protection, geothermal, and hydrocarbon reservoir prediction, water recovery, or storing H〈sub〉2〈/sub〉 or CO〈sub〉2〈/sub〉 in the subsurface.〈/p〉
    Description: Plain Language Summary: In the Earth's crust fluid flow can occur in fractured rock and depending on the composition of the fluid and physical conditions minerals can precipitate or dissolve. This affects the properties of the rock system and is for example, of interest to subsurface engineering applications. In this work we simulate observations of laboratory experiments at the grain scale, where crystals grow in an open fracture during fluid flow. In these experiments, the growth rate of the crystals varies along the fracture since the supersaturation of the fluid decreases due to the crystallization. We use a multiphase‐field model for the numerical simulation of crystal growth in the open fracture and combine it with reactive fluid flow. With the presented model the driving force for grain growth is coupled to the local supersaturation, which enables the incorporation of reactive mass transport in open fractures. Our phase‐field simulations agree with the laboratory experiments. The presented simulative approach can be used for upscaling the results on microscale to larger length and time scales and can help to better predict the subsurface behavior for example, of groundwater, fractured geothermal, and hydrocarbon reservoirs.〈/p〉
