Skew Disperson and Continuity of Local Time

Creator:

Appuhamillage, Thilanka A., Waymire, Edward C., Thomann, Enrique A., Bokil, Vrushali A., and Wood, Brian D.

Abstract:

Results are provided that highlight the effect of interfacial discontinuities in the diffusion coefficient on the behavior of certain basic functionals of the diffusion, such as local times and occupation times, extending previous results in [2, 3] on the behavior of first passage times. The main goal is to obtain...

Coupled transport and reaction kinetics control the nitrate source-sink function of hyporheic zones

Creator:

Zarnetske, Jay P., Haggerty, Roy, Wondzell, Steven M., Bokil, Vrushali A., and Gonzalez-Pinzon, Ricardo

Abstract:

The fate of biologically available nitrogen (N) and carbon (C) in stream ecosystems is controlled by the coupling of physical transport and biogeochemical reaction kinetics. However, determining the relative role of physical and biogeochemical controls at different temporal and spatial scales is difficult. The hyporheic zone (HZ), where groundwater–stream water...
