9 Building a Static Model from Lithologic Data
When sufficient geologic data are available for defining a groundwater modeling framework, modeling software such as RockWorks can be used to create a grid of lithologic types throughout the model domain, with hydraulic properties assigned to each lithologic type (Figure 18). An animated view of the model is presented in this video. The 35 second (~80Mb) animation rotates the basin in three-dimensional space while showing: the bedrock surface; the lithologic logs used to determine the lithology distribution; fence diagrams along a few cross sections; and the final solid model sequentially sliced from west to east and back, then from south to north and back. Fine-grained materials are displayed as purple, medium-grained as yellow, and coarse-grained as orange with faults as red.
