About this event

The USGS Arizona Water Science Center is the water-science focused branch of the U.S. Geological Survey in Arizona. The Center's mission is to collect and interpret hydrologic data to support natural resource decision making in Arizona and the Nation. Much of the work of the Center applies established techniques of monitoring and assessment, but we also advance hydrologic science through the development of new approaches. In addition to a brief overview of Center, this talk will describe two emerging approaches: 1) use of Unmanned Aerial Systems (UAS) for hydrologic applications and, 2) monitoring of changes in the Earth's gravitational field to monitor aquifer storage change.

Presenter: Jim Leenhouts, USGS Arizona Water Science Center

Jim joined the USGS Arizona Water Science Center as a hydrologist in 2000. From 2000 to 2007, Jim worked on three projects in the Upper San Pedro Basin. The first was to quantify the groundwater and surface-water requirements of the riparian vegetation and the second was to quantify stream-aquifer interactions as part of the groundwater model development. Following these projects, Jim led the “Section 321” project that evaluated the water budget and hydrogeology for the San Pedro basin and summarized findings in annual reports to congress. A key aspect of this work was interpreting the wide variety of data collected and working with the Upper San Pedro Partnership to assess progress toward sustainable withdrawals of groundwater. From 2007 to 2013, Jim served as the Center’s Associate Director for Investigations. Currently, Jim is the Center Director of the Arizona Water Science Center.

Presenter: Geoff DeBenedetto, USGS Arizona Water Science Center

Geoff, a Geographer with the USGS Arizona Water Science Center, has a background in aviation, remote sensing, and USGS stream gaging technique. He works with a small team of talented Hydrologists at the USGS developing and implementing tools to improve data collection and analysis with the goal of improving daily operations, as well as, providing timely information to stakeholders and cooperators for monitoring and decisions-making.
