SWR Research Topics

Overview

SWR conducts studies on a wide variety of topics related to land use change and climate change impacts on water resources, naturally occurring contaminants in aquifers that are described below.

Land Use Change Impacts on Water Resources (Ecohydrology)

  • Global Impacts of Conversions from Natural to Agricultural Ecosystems on Water Resources: Quantity versus Quality
  • Impact of Land use and land cover change on groundwater recharge and quality in the southwestern US
  • Subsurface Environmental Tracers as Archives of Past Land Use Change Impact son Water Resources in the US Southern High Plains
  • Evaluation of evapotranspirative covers for waste containment in semiarid regions in the southwestern US
  • Evaluation of Biofuels as an Alternative Energy Source

Climate Variability/Change Impacts on Water Resources

  • Ecological Controls on Water Cycle Response to Climate Variability
  • Variations in Flow and Transport in Thick Desert Vadose Zones in Response to Paleoclimatic Forcing (0–90 kyr): Field Measurements, Modeling, and Uncertainties;

Groundwater Surface Water Interactions

Groundwater Recharge

  • Global Synthesis of Groundwater Recharge in Semiarid and Arid Regions
  • Assessing Controls on Diffuse Groundwater Recharge Using Unsaturated Flow Modeling
  • Choosing Appropriate Techniques for Quantifying Groundwater Recharge

Focused and Preferential Flow in Unsaturated Media

  • Focused Flow in Fissured Sediments in the Chihuahuan Desert
  • Focused Recharge Beneath Ephemeral Lakes (Playas) in the Southern High Plains, Texas

Naturally Occurring Contaminants in Groundwater

  • Arsenic
