We seek to understand and model the effects of salinity on geochemical processes occurring in aqueous environments including nanopores and interlayers in clay media, thin water films in unsaturated porous media, and solutions in which mineral nanoparticles nucleate, aggregate and grow. The overall goal is to identify conceptual models of salinity effects on complex geochemical…
The TOUGH (“Transport Of Unsaturated Groundwater and Heat”) suite of software codes are multi-dimensional numerical models for simulating the coupled transport of water, vapor, non-condensible gas, and heat in porous and fractured media. Developed at the Lawrence Berkeley National Laboratory (LBNL) in the early 1980s primarily for geothermal reservoir engineering, the suite of simulators is now widely used throughout the world.
The Used Fuel Disposition (UFD) Campaign was initiated in 2009 to support the Blue Ribbon Panel review of high-level nuclear waste policy in the United States. Our work is organized in the these areas: Natural Systems Research, Engineered Barrier Research, System-Level Modeling, and International Activities within UFD.
The Watershed Function SFA is developing a predictive understanding of how mountainous watersheds retain and release water, nutrients, carbon, and metals. In particular, the SFA is developing understanding and tools to measure and predict how droughts, early snowmelt, and other perturbations impact downstream water availability and biogeochemical cycling at episodic to decadal timescales.
