Other sources of data used in 3D geologic models: Lithologic, geophysical, geochemical, and isotopic logs from water wells, coupled with the geology of adjacent outcrops and fundamental concepts of depositional environments and sedimentary architecture are used to produce a 3-dimensional model of Cenozoic sedimentary sequences in the Santa Clara Valley. These modeling efforts focus on determining 3-dimensional sedimentary characteristics that can act as surrogates for physical properties such as permeability, density, and seismic wave velocity. The modeling is iterative and subject to repeated testing by comparison with the results of a drilling program conducted cooperatively by the U.S. Geological Survey and the Santa Clara Valley Water District.
