A data storage and retrieval system for hydrogeologic data is designed to produce lithology distribution maps, isopachous maps, and cross sections showing the boundaries and hydraulic characteristics of river alluvium. Emphasis has been placed on selecting and coding characteristics of the alluvial sediments which will facilitate description in terms of hydraulic properties and in a manner convenient for interpretation. The hydraulic properties of fluvial deposits for input to the system are defined based on analysis of core samples and pump tests. A ground‐water study, for which this retrieval system was designed, is part of the research being conducted by the Agricultural Research Service in the Washita River valley in south‐central Oklahoma near Chickasha. In the ground‐water study, maps and cross sections from the retrieval system are used—in conjunction with the hydraulic coefficients and water‐level records—to estimate the rate of ground‐water flow and storage for selected time increments. This information is needed in the study for developing a mathematical model of surface runoff as influenced by upstream tributary development.
