On calibration of the UZ site-scale model of Yucca Mountain
- Lawrence Berkeley National Lab., CA (United States); and others
The 3-D unsaturated-zone site-scale model (model) of Yucca Mountain, under development at the Lawrence Berkeley National Laboratory (LBNL) in cooperation with the U.S. Geological Survey (USGS), has been calibrated against the measured data available for the site. This is an important step in the model development and verification process. The reliability and the accuracy of the model predictions of the moisture, gas, and heat flow and distributions in the mountain depend upon model parameters, imposed boundary conditions, and realistic representations of different-scaled heterogeneous geological features, among other factors. Even though considerable efforts have been made in recent years to investigate hydrologic and rock properties of the Yucca Mountain site, many of the site-specific parameters, such as fracture and fault properties and net infiltration rates, are not well-defined at present. Therefore, as part of the continuous development of the model, a comprehensive calibration study has been conducted to examine and enhance the model capability in predicting the site conditions. This paper presents some of our model calibration results, including incorporation and calibration of (1) saturation and water potential data, (2) gas pressure data, and (3) thermal data. Much more detailed information about the calibration is found in Wu et al.
