fracture flow deep in the unsaturated zone. This paper presents the history of the evolution of conceptual models of hydrology and numerical models of unsaturated zone flow at Yucca Mountain, Nevada (Flint, A.L., Flint, L.E., Kwicklis, E.M., Bodvars. The purpose of this paper is to describe and trace the evolution of the conceptual model of groundwater flow in the unsaturated zone at Yucca Mountain. For this discussion, a conceptual model is simply a relevant set of concepts that describe, in a qualitative way, the behavior of a natural system. Get this from a library! Conceptual hydrologic model of flow in the unsaturated zone, Yucca Mountain, Nevada. [Parviz Montazer; William E Wilson; United States. Department of Energy.; Geological Survey (U.S.)]. Conceptual and numerical flow and transport models of Yucca Mountain indicate that infiltration is highly variable, both spatially and temporally. Flow in the unsaturated zone is predominately through fractures in the welded units of the Tiva Canyon and Topopah Spring Tuffs and predominately through the matrix in the Paintbrush Tuff nonwelded units and Calico Hills Formation.
The current () conceptual model of flow through the unsaturated zone at Yucca Mountain as presented here reflects processes invoked by hydrologic researchers that have participated on the Yucca Mountain Project, as well as those concepts that are most consistent with the measured data and by: () conceptual model of climate, surface infiltration, and percolation processes through the unsaturated zone and groundwater flow patterns as a framework for de- scribing the current hydrologic conditions at Yucca Mountain, with emphasis on the unsaturated zone. Flow in the saturated zone is described only briefly and only inCited by: The conceptual hydrogeological model for describing TH processes at Yucca Mountain is based on the current conceptual model of the UZ flow model. In this hydrogeological conceptual model, the UZ system consists of multi-layered hydrogeologic units determined primarily by the degree of welding in Yucca Mountain tuffs (Montazer and Wilson, ).Cited by: 9. The unsaturated zone at Yucca Mountain is being modeled using a three-dimensional, dual-continuum numerical model to predict the results of measurements and observations in new boreholes and.
