Overall Research Objectives
- Improve quantitative understanding of arid-site processes affecting contaminant transport and release to environmental receptors by integrating existing and new information into physically based numerical and analytical models.
- Fill gaps in present knowledge of soil–plant–atmosphere interactions in arid regions with respect to water, gas, and contaminant transport. Explain effects of such interactions on transport processes and on environmental health through analyses of spatial and temporal heterogeneities and trends, and through targeted data collection.
- Develop efficient methods for characterizing anthropogenically introduced and naturally occurring contaminant distributions in order to test theories of flow and transport processes at the field scale.
