Flow and transport around a noncontinuous horizontal layer at Yucca Mountain.

摘要

Computer simulations were used to examine the effect of a noncontinuous horizontal layer on the flow field and contaminant transport of a simplified conceptual model. The domain consisted of four different material types, where the pinched-out layer had a hydraulic conductivity one order of magnitude less than the other three zones. The boundary conditions were modified for three different simulations. The model results indicate that the boundary conditions used affect the results and are an important consideration in modeling. This implies that one-dimensional modeling is not adequate to represent the system. 10 refs., 9 figs., 1 tab.
