The book comprises the 3rd collection of benchmarks and examples for porous and fractured media mechanics. The 3rd THMC benchmark book also introduces benchmark-based tutorials, therefore the subtitle is selected as “From Benchmarking to Tutoring”.

The collaborative Pilot Project, titled “Comparison of Thermo-Hydro-Mechanical-Chemical (THMC) Processes in Bentonite Barrier Systems”, aims to investigate the fundamentals, conduct laboratory and field experiments, and develop numerical models for barrier systems that ensure the safe isolation of radioactive waste in deep geological repositories.

This book is open access book. The collaborative Pilot Project, titled “Comparison of Thermo-Hydro-Mechanical-Chemical (THMC) Processes in Bentonite Barrier Systems”, aims to investigate the fundamentals, conduct laboratory and field experiments, and develop numerical models for barrier systems that ensure the safe isolation of radioactive waste in deep geological repositories. This book compares methodologies and technologies used in experimental laboratory and field research, as well as systems analysis, in a collaborative work of German and Chinese scientists. Both parties have access to exceptional experimental and modelling research capabilities. The Beishan underground research laboratory (URL) is currently under construction in Gansu, China. It will serve as an international collaboration platform for URL research in the future. International cooperation is essential for excellent research and development due to the high cost of scientific programmes and technical operation of URLs, making it a precondition for providing secure solutions. This is important not only for deep geological repositories for radioactive waste disposal but also for other geoenergy applications, such as energy storage and geothermal energy utilization.

The present book provides guidance to understanding complicated coupled processes based on the experimental data available and implementation of developed algorithms in numerical codes. Results of selected test cases in the fields of closed-form solutions (e.g., deformation processes), single processes (such as groundwater flow) as well as coupled processes are presented.It is part of the OpenGeoSys initiative - an open source project to share knowledge and experience in environmental analysis and scientific computation with the community.

This book presents a new suite of benchmarks for and examples of porous media mechanics collected over the last two years. It continues the assembly of benchmarks and examples for porous media mechanics published in 2014. The book covers various applications in the geosciences, geotechnics, geothermal energy, and geological waste deposition. The analysis of thermo-hydro-mechanical-chemical (THMC) processes is essential to many applications in environmental engineering, such as geological waste deposition, geothermal energy utilisation, carbon capture and storage, water resources management, hydrology, and even climate change. In order to assess the feasibility and safety of geotechnical applications, process-based modelling is the only tool that can effectively quantify future scenarios, a fact which also creates a huge burden of responsibility concerning the reliability of computational tools. The book shows that benchmarking offers a suitable methodology for verifying the quality of modelling tools based on best practices, and together with code comparison fosters community efforts. It also  provides a brief introduction to the DECOVALEX, SeSBench and MOMAS initiatives. This benchmark book is part of the OpenGeoSys initiative – an open source project designed to share knowledge and experience in environmental analysis and scientific computation.

The book comprises the 3rd  collection of benchmarks and examples for porous and fractured media mechanics. Analysis of thermo-hydro-mechanical-chemical (THMC) processes is essential to a wide area of applications in environmental engineering, such as geological waste deposition, geothermal energy utilization (shallow and deep systems), carbon capture and storage (CCS) as well as water resources management and hydrology. In order to assess the feasibility, safety as well as sustainability of geoenvironmental applications, model-based simulation is the only way to quantify future scenarios. This charges a huge responsibility concerning the reliability of conceptual models and computational tools. Benchmarking is an appropriate methodology to verify the quality and validate the concept of models based on best practices. Moreover, benchmarking and code comparison are building strong community links. The 3rd THMC benchmark book also introduces benchmark-based tutorials, therefore the subtitle is selected as “From Benchmarking to Tutoring”. The benchmark book is part of the OpenGeoSys initiative - an open source project to share knowledge and experience in environmental analysis and scientific computation. The new version of OGS-6 is introduced and first benchmarks are presented therein (see appendices).
