"The definitive treatise on the subject for many years to come"
--Prof. Ruben Juanes, MIT

Authoritative textbook that provides a comprehensive and up-to-date introduction to fluid flow in fractured rocks

Fluid Flow in Fractured Rocks provides an authoritative introduction to the topic of fluid flow through single rock fractures and fractured rock masses.

This book is intended for readers with interests in hydrogeology, hydrology, water resources, structural geology, reservoir engineering, underground waste disposal, or other fields that involve the flow of fluids through fractured rock masses. Classical and established models and data are presented and carefully explained, and recent computational methodologies and results are also covered. Each chapter includes numerous graphs, schematic diagrams and field photographs, an extensive reference list, and a set of problems, thus providing a comprehensive learning experience that is both mathematically rigorous and accessible.

Written by two internationally recognized leaders in the field, Fluid Flow in Fractured Rocks includes information on:
* Nucleation and growth of fractures in rock, with a multiscale characterization of their geometric traits
* Effect of normal and shear stresses on the transmissivity of a rock fracture and mathematics of fluid flow through a single rock fracture
* Solute transport in rocks, with quantitative descriptions of advection, molecular diffusion, and dispersion

Fluid Flow in Fractured Rocks is an essential resource for researchers and postgraduate students who are interested in the field of fluid flow through fractured rocks. The text is also highly suitable for professionals working in civil, environmental, and petroleum engineering.

"Fractures are ubiquitous in geologic formations, and they are often the key determinants of fluid flow and transport in the subsurface, controlling processes that are critical in environmental flows and in the energy transition, such as geothermal energy extraction, in situ mining of metals and minerals, and migration of radionuclides from geological nuclear waste disposal facilities. Despite their fundamental role in subsurface technologies, modeling fluid flow in fractured rocks is notoriously challenging because of their multiscale (fractal) nature, and the complex behavior that emerges from their interconnected network structure. In this book, world-leading experts Zimmerman and Paluszny present a didactive and insightful synthesis of the physics, mathematics, and computational modeling of fluid flow in fractured rock, that is destined to become the definitive treatise on the subject for many years to come."
