Maximum Weighted Log-Likelihood Estimation for Parameterization Selection Uncertainty
Hydraulic conductivity identification remains a challenging inverse problem in groundwater modeling because of inherent non-uniqueness and lack of flexibility in parameterization methods....
Evaluation of a Bias Aware Ensemble Kalman Filter Using a Scaled Aquifer Transport Experiment
In this study, a bias-aware Ensemble Kalman Filter (EnKF) is applied to a scaled aquifer transport experiment (1-cm of the model equals 1-m at field scale and 1-day of model transport...
Monitoring and Quantifying Rate-Limited Mass Transfer Using Geoelectrical Measurements
Non-Fickian solute-transport behavior has been observed at research and aquifer remediationsites in diverse geologic settings. Anomalous behavior such as concentration rebound, long breakthrough...
Evaluation of Satellite-Based Impervious Surface Data for the Mid-Atlantic Region Using an Independently Collected, High-Resolution Validation Database
Satellite-based estimates of impervious surfaces are being produced for the entire United States as part of the U.S. Geological Survey's (USGS) Landsat-based National Land Cover Database...
Stochastic Conditional Simulation of Berea Sandstone Geophysical Properties with a Counterpropagation Neural Network
The ability of a counterpropagation neural network to produce stochastic conditional simulations is applied and evaluated on a real dataset. This network functions as a nonparametric clustering...

Mathematical Modeling of Watershed Hydrology
Mathematical modeling of watershed hydrology is employed to address a wide spectrum of environmental and water resources problems. A historical perspective of hydrologic modeling is provided,...
Bayesian Approach to Support Design of a Groundwater Long Term Monitoring Plan
This paper discusses a retrospective data assimilation approach that allows one to examine the spatial and temporal differences between forecast and observed states. Their stability, or...
The Accuracy of Extrapolated Design Estimates with Hydrologic and Environmental Models
Extrapolation error in water resources and environmental modeling has not been the subject of adequate study in the past. In research and design, estimates obtained from regression models...
