Groundwater Monitoring Network Design Using Coupled Monte Carlo Simulation and Optimization
This paper presents a method for the design, under uncertainty, of a groundwater well network for compliance monitoring at a waste disposal site. A numerical model of contaminant transport...
Application of Hydrodynamic and Water Quality Models at a Superfund Site in Montana
The water quality model applied to the site is the EPA-supported hydrodynamic and water quality model WASP4 with a modification to enable it to better simulate riverine systems. To provide...
Geostatistical Global Estimates and Sampling Design
In the environmental assessment of a contaminated site, several different evaluation criteria could be considered such as: estimation of the overall average contaminant concentration in...
Geostatistics in Estimating Chemical Residuals at a Site
Kriging with generalized covariances is used to evaluate the effectiveness of remediation and cleaning of a contaminated site. The goal is to estimate: a) the amount of total volatile...
Two-Dimensional Inter-Rill Flow Model for the Analysis of Agricultural Runoff
This paper presents a model describing the flow field for the inter-rill component of agricultural runoff. Given rainfall intensity, surface roughness, rill spacing, and longitudinal and...
