Digitized Contours from Georeferenced Plate from "Analog simulation of water-level declines in the Sparta Sand, Mississippi Embayment" (Reed, 1972)

Published by U.S. Geological Survey | Department of the Interior | Catalog Last Checked: August 01, 2026 at 05:01 AM | Dataset Last Updated: December 01, 2022 at 12:00 AM
A digital dataset of analog simulation of water-level declines in the Sparta Sand, Mississippi Embayment in Missouri, Kentucky, Arkansas, Tennessee, Louisiana, and Mississippi was developed from J.E. Reed's "Analog simulation of water-level declines in the Sparta Sand, Mississippi Embayment" (1972). The plate was georeferenced to North American Datum 1983 and projected to USA Contiguous Albers Equal Conic (U.S. Geological Survey version) projection (standard parallels 29.5 and 45.5 degrees, central meridian -96 degrees, and latitude of origin 23 degrees). Once georeferenced (using ArcMap v 10.4.1), individual potentiometric contours were digitized manually. Figures included in the digital dataset are figures 2 through 5 (predevelopment to predicted declines for 1990).
