City of Jackson, Mississippi Ground-Water Monitoring

Long-term water-level records are needed to evaluate the effects of climatic variations on the recharge to and discharge from the ground-water systems, to provide a data base from which to measure the effects of development, to assist in the prediction of future supplies, and to provide data for management of the resource.

LAWSC provides easy flood tracking on the web – 25 May 2007

Flooding is a concern for everyone in Louisiana. Floods demand immediate and decisive action by governmental entities, businesses, and individual citizens, all of whom have to make critical decisions that directly impact the extent, duration, and mitigation of losses resulting from flooding. How high will the water get? How long will the flood last? What areas will be affected? What roads will...

The impact of ventilation patterns on calcite dissolution rates within karst conduits

Erosion rates in streams vary dramatically over time, as differences in streamflow and sediment load enhance or inhibit erosion processes. Within cave streams, and other bedrock channels incising soluble rocks, changes in water chemistry are an important factor in determining how erosion rates will vary in both time and space. Prior studies in...
