Subsurface Injection of Radioactive Tracers: Field Experiment for Model Validation Testing

摘要

A field experiment was undertaken in 1980 and 1981 to provide data to test the limits of model predictions. The purpose of the report is to provide a complete record of data generated during that field experiment for use as a model validation test case. The report combines the information in Sisson and Lu (1984) with unpublished laboratory and field data on the hydraulic properties of the sediments and core data collected at the end of the experiment. The unique features of the experiment were the documented control of the inputs, the three-dimensional nature of the experiment, the measurement of radioactive tracers in situ, and the use of multiple injections. The in situ monitoring methods were neutron moderation for water content and gamma energy analysis for tracer concentration. The data are provided on 3.5-in. diskettes. The data include observation and injection well construction details, injection solution concentrations, radioactive tracer and water content distributions in space and time, neutron probe calibration information, and sediment properties determined in both the laboratory and field.
