Comments on Geologic Parameters
11 Flow Direction:
Flow directions are inferred from potentiometric contour maps of the carbonate aquifers in Nevada in Prudic and others (1995) and Thomas and others (1986). Arrows indicating preferred ground-water flow directions in Tertiary basin-fill sandstones in northwestern Arizona and southwestern Utah are shown in Robson (1996).
