The student members of the Rho chapter of Sigma Gamma Epsilon at Indiana University invite you to participate in the annual Crossroads Geology Conference at Indiana University. This conference is a student-organized event featuring research presentations by graduate and undergraduate students in the geological and environmental sciences from a number of regional colleges and universities, at Indiana University in Bloomington.
If you would like us try to place you with a student host, please indicate so on your abstract submission.

One of the most urgent challenges facing the world today is ensuring an adequate supply and quality of water for human and ecosystem needs in the face of climate variability and change. Recent increases in air temperature are resulting in increases in evaporation/evapotranspiration and changes in precipitation, leading to an overall intensification of the hydrologic cycle. This intensification is projected to continue into the 21st century at potentially faster rates. Using observed climate data and projected climate data from General Circulation Models (GCMs), this talk examines how these changes in the hydrologic cycle will affect water resources and their quality throughout the western United States. These changes will not only impact agricultural and urban communities that depend on these resources, but also aquatic species that are adapted to particular hydrologic regimes and stream temperatures. This work indicates that changes in air temperatures and precipitation will lead to changes in streamflow magnitude and timing (shifting streamflow peaks earlier into the year by 1-2 months), as well extreme events such as flooding and droughts. The streamflow changes coupled with air temperature increases will also result in stream temperature changes by 1-5 °C, subsequently affecting habitat ranges for aquatic species such as trout and salmon that are both culturally and economically significant. These results indicate a very different hydroclimatic future for the western United States, thus requiring an adaptation of water resource and aquatic species management.
