Environmental Remediation Sciences Program

Modeling & High Performance Computing

The ERSP seeks to encourage the incorporation of computational modeling as a component of subsurface research. Whether at the molecular scale, the field scale or somewhere in between, conceptual and computational models of processes affecting contaminant transport are important elements of ERSP investigations. Computational models are an integral part of subsurface research and help to clarify research hypotheses and guide future research directions. ERSP science teams, particularly the field research components of the program, are encouraged to partner with modelers and computational scientists to provide state-of-the-science descriptions of subsurface processes and predictions of contaminant transport to aid decision-making for environment remediation. ERSP also partners with the U.S. DOE Office of Advanced Scientific Computing Research (ASCR) on projects of mutual interest such as the simulation of groundwater reactive transport processes on high performance computers under the SciDAC program.

SciDAC Review. Science for Problems Under the Surface. Processes in Earth's subsurface are central players in several critical, interrelated energy and environmental issues. Leadership-class computing will soon be brought to bear on understanding and predicting these processes across a wide range of time and space scales. Read about it online or download the pdf.

Currently, the ERSP supports (with ASCR) two SciDAC-II projects.
