New Approaches In Hydrogeophysical Model Predictions: Case Studies From theP Reactor Area, Savannah River Site, South Carolina
… used to characterize, monitor, and investigate hydrogeological parameters and processes in the shallow subsurface at relevant spatial scales in a minimally invasive manner.</p> <p>Near-surface geophysical methods hold the potential to provide qualitative and quantitative information about …

Groundwater Modeling and Hydrogeological Parameter Estimation: Potomac Aquifer System, SWIFT Research Center
… wells (MW) at the SWIFTRC were used to calculate hydrogeological parameters (transmissivity, hydraulic conductivity, specific storage, and storage coefficient). Two sets of data were analyzed from before and after TW-1 was rehabilitated to account for the change in the flow distribution to each …

HYDROGEOLOGICAL CHARACTERIZATION OF A LEGACY WASTE STORAGE SITE AND THE CHALLENGE OF COMMUNICATING UNCERTAINTY
… transport models rely on estimates of hydrogeological parameters that can range from two to three orders of magnitude. The effect parameter variability has on the results of groundwater and contaminant transport modelling was assessed for a legacy nuclear waste storage site in southern …

Impact of uncertain input on parameter estimation in groundwater model
… issues are far from being solved. When important hydrogeological parameters like transmissivity and storativity are estimated using regression-based inverse methods, it is assumed that all other parameters and quantities are known. In particular, it is assumed that pumping rates are known. This …

Analytical and Numerical Modelling of Thermal Conductive Heating in Fractured Rock
… conducted to assess the relative importance of hydrogeological parameters (hydraulic gradient, fracture aperture, fracture spacing) and rock material properties (density, thermal conductivity, heat capacity). Hydrogeological parameters were far more important than rock material properties in …

Accounting for parameter uncertainty and temporal variability in coupled groundwater-surface water models using component and systems reliability analysis
… depends upon uncertain and spatially variable hydrogeological parameters, as well as temporally uncertain streamflow. In this study a novel component - systems reliability analysis framework is developed to assess risk. Physical parameters uncertainty is studied in light of the Glover-Balmer …

A fully Bayesian approach to uncertainty quantification of groundwater models
… solute transport processes. Since the important hydrogeological parameters of these models (e.g., hydraulic conductivity) cannot be measured, they are normally estimated by model calibration. In addition, groundwater models are often subject to input data errors, as some of the input forcings …

Assessing long-term conservation of groundwater resources in the Ogallala Aquifer Region using hydro-agronomic modeling
… HPA. Major findings include: 1) climate-related parameters significantly affect crop yields, especially for maize and sorghum, and soybean and winter wheat yields are sensitive to a combination of cultivar genetic parameters, soil-related parameters, and climate-related parameters; 2) Climatic …
