Development of Systematic Approaches for Calibration of Subsurface Transport Models Using Hard and Soft Data on System Characteristics and Behavior
Abstract
This research seeks to extend and combine tools for parameter estimation and geostatistical simulation for use with groundwater flow and transport models used by the Army. Funds were added to include a research task to investigate the soil moisture distribution in the shallow subsurface affected by buried objects and heterogeneity in the soil under various surface conditions. The primary aims of the project are to: (1) develop an improved understanding of how to include in a systematic way the geostatistical description of aquifer heterogeneity to calibration, (2) develop methods to condition parameter estimation to results from pumping tests/tracer tests and lithology data, (3) use sparsely sampled lithology and drawdown data to determine calibration parameters at the field scale, (4) develop a data set that describes the spatial and temporal behavior of soil moisture retention in simple heterogeneous systems and understand the behaviors at a resolution that is significantly finer (order of ~cm) than those used in other applications, (5) Develop a fundamental scientific basis for understanding heat, liquid water and water vapor transport around buried objects in the shallow subsurface and (5) develop a better understanding of the characteristics of disturbed soils through the characterization of hydraulic/thermal properties.
