Gas-Water-Rock Interactions and Implications for Geoenvironmental Issues
Description
Water and gas, as the two most common fluids and primary geologic forces, are crucial components in various geological processes. Gas-water-rock interactions play indispensable roles in the evolution of geoenvironmental issues. For example, the accurate prediction of groundwater flow and contaminant transport requires a profound understanding of physicochemical processes that occur among liquid, solid, and gas phases. At present, gas-water-rock interactions related to the transport and retention of toxic contaminants such as heavy metals and organic contaminants in aquifers and vadose zones should be paid more attention, due to the release of toxic contaminants from the intensive human activities. In addition, gas-water-rock reaction might change stress field, groundwater seepage field, and properties of rocks and soils, which subsequently leads to instability of slope and landslide hazards. A rapid sliding rock mass is likely to trigger waves or stir atmosphere generating air blasts and facilitating its transport, both aggravating the hazards.
We invite authors to submit novel research papers and review articles to advance the understanding of gas-water-rock interactions.
Potential topics include but are not limited to the following:
- Transport and retention mechanisms of toxic pollutants in soils, vadose zones, and aquifers. Example of toxic contaminants may be nitrate, arsenic, heavy metals, and organic contaminants
- Origin and distribution of toxic contaminants in groundwater because of the impacts of human activities
- Mechanisms of rock mass deterioration due to water-rock interactions and their role in causing landslides
- Mechanisms of slope failure triggered by rainfall and water impoundment
- Mechanisms of landslide-triggered wave and aerodynamics of rapid landslides
- Applications of gas-water-rock interaction studies in geothermal surveys
- New numerical simulation methods of gas-water-rock interactions
