SEPHAS: Scaling Environmental Processes in Heterogeneous Arid Soils

Boulder City Facility in Southern NevadaBoulder City Facility in Southern NevadaSEPHAS is a research program which focuses on the scaling of subsurface and landscape-interface environmental processes.

Scaling of environmental processes, defined as the transfer of knowledge from one spatial or temporal scale to another, is often hampered by natural heterogeneity which typically is not limited to the experimental scale. The disparity between measurement scale and scale of interest limits our ability to characterize environmental processes and how the processes interact with one another. Research facilities that span these scales are either rare or nonexistent.
