Historical Background on Assessment the Performance of the Waste Isolation Pilot Plant

“…The 1987 study was followed by two more modeling studies by INTERA, Inc., for Sandia in 1988(LaVenue et al, 1988, 1990 in support of the Supplemental EIS. The differences in the models were that vertical leakage was not included and brine density varied spatially but was held constant over time.…”

Ground-water flow modeling of the Culebra dolomite

“…The present study is the first that provides steady-state head calibration to undisturbed head conditions and transient head calibration to several large-scale The studies by Haug et al (1987) and LaVenue et al (1988) utilized the model transmissivity distribution from calibration to the steady-state head distribution to investigate the model's suitability to simulate shaft effects and head changes resulting from large-scale pumping tests. However, these previous studies did not include extensive calibration efforts to improve the model's transmissivity distribution to simulate both steady-state and transient heads.…”

“…La Venue et al (1988) calculated a mean thickness of 25 ft (7.7 m) for the Culebra based on 78 15 boreholes. This mean thickness has been used uniformly for the Culebra in PA calculations.…”
