The subsurface of the Earth provides space for many geotechnical applications for energy supply and storage such as geothermal energy utilization, oil and gas production, carbon dioxide sequestration and waste deposition. To assess the feasibility as well as the environmental impact of geotechnical operations, numerical simulation plays an important role as modelling is the only way to create  predictions. In order to guarantee confidence in and reliability of simulation tools, benchmarking is an important scientific tool to qualify appropriate modelling approaches. SS Bench is an initiative for benchmarking subsurface environmental simulation methods with a current focus on reactive transport processes. This workshop is conducted in conjunction with CO2BENCH, a related benchmarking initiative dealing with carbon dioxide storage in geological formations. (Kolditz et al., 2012)

This book comprises an assembly of benchmarks and examples for porous media mechanics collected over the last twenty years. 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, even climate change. In order to assess the feasibility as well as the safety of geotechnical applications, process-based modelling is the only tool to quantify future scenarios. This denotes a huge responsibility concerning the reliability of computational tools. Benchmarking is an appropriate methodology to verify the quality of modelling tools based on best practices. Moreover, benchmarking and code comparison foster community efforts. The benchmark book is part of the OpenGeoSys initiative - an open source project to share knowledge and experience in environmental analysis and scientific computation.
