Thermo-hydro-mechanical processes in fractured rock formations during a glacial advance
Thermo-hydro-mechanical processes fractured rock formations glacial advance
2015/8/6
The paper examines the coupled thermo-hydro-mechanical (THM) processes that develop in a fractured rock region within a fluid-saturated rock mass due to loads imposed by an advancing glacier. This sce...
A new model of terrestrial rock weathering – the Rock Geochemical Model (RokGeM) – was developed for incorporation into the GENIE Earth System modelling framework. In this paper we describe the model....
