Surface Water/Groundwater Interactions in Arizona: Physical Realities and Experiences in the Real World

November 20, 2014- 12:00 pm - 11:55 pm

Brown bag seminar, “Surface Water/Groundwater Interactions in Arizona: Physical Realities and Experiences in the Real World,” presented by the WRRC (Water Resources Research Center) of the University of Arizona. Streams and aquifers are hydraulically connected in many hydrologic systems across Arizona. Such a connection occurs when the groundwater level in an aquifer intersects a stream, spring, or even the roots of riparian plants. In these hydraulically connected systems, the surface water and groundwater interact as a stress imposed on one part has an effect on the other. Often this interaction is observed as a reduction in stream base flow caused by groundwater withdrawals from a connected aquifer – a process often called “streamflow depletion” or “capture”. An aquifer recharge project or a change i n climate represents stresses that also have effects. Hydrologists at the USGS Arizona Water Science Center have worked across the state to develop groundwater-flow models for assessing and communicating groundwater/surface-water interactions. These tools have been used for making various resource management decisions, but they have also initiated useful and revealing dialogs regarding the connections of surface water to groundwater. The presenter of this seminar, Jim Leenhouts, is Director of the Arizona Water Science Center. He has worked in the Verde River basin to explain surface-water/groundwater interactions as represented by the USGS Northern Arizona Regional Groundwater Model. Location: WRRC Sol Resnick Conference Room (350 N. Campbell Ave.), Tucson. The WRRC offers remote access to Brown Bag Seminars via GoToWebinar.
