We use moderate resolution satellite data to assess live fuel condition for estimating fire danger. Using 23 years of vegetation condition measurements, we are able to determine the relative greenness of wildland vegetation susceptible to burning.
The Marcellus shale is a black shale unit in the eastern US. It has economic use as a source of natural gas. Environmental concerns arising from the process of exploiting this resource include water supply and wastewater disposal.

Overview of a project in Virginia to develop a program for assessing public supply source waters to determine their susceptibility to contamination and to determine which systems need detailed source-water assessments.
Description of project to study the distribution of saline water in the aquifers of the Coastal Plain of Virginia and the potential for saline water intrusion by evaluating chloride concentrations and the factors affecting chloride distribution.
Brief description of project for the Federal Emergency Management Agency to prepare and modify Flood Insurance Rate Maps based on flood frequency analysis, ground surveys, and flood profiles in Virginia.
Overview of a project to evaluate existing methods used by Virginia Dept. of Transportation to estimate flood hydrographs from small drainage basins, and evaluate the use of dimensionless hydrographs to estimate runoff volumes.
