Alluvial fans provides challenges to engineers, scientists, and policy makers in determining extent and magnitude of flooding in areas downstream. This field trip will include a site visit to an active alluvial fan and discussion on flooding mitigation. McMicken Dam is an example of infrastructure that was constructed in the 1950s to mitigate alluvial flooding, 8-miles long it now protects almost 300,000 residents of Maricopa County and billions of dollars’ worth of property and infrastructure. Subsidence from groundwater pumping created fissures that required extensive rehabilitation of the south end of the structure. Participants will see recent rehabilitation for the dam and outlet facilities. The second part of the tour will focus on the Gila River and Tres Rios Restoration areas and improvements being made to promote natural floodplain management and habitat restoration. The high ground water table in the river creates different challenges. On route to these features, participants will learn about geomorphology and desert hydrology, partial dam replacement basin design for fissures, river vegetation rehabilitation, and locations for native vegetation replacement. Stops will occur along the Gila and Salt River as time allows on the route back to the Convention Center.

Ephemeral desert washes can become raging rivers very quickly. The nature of flash flooding in arid environments requires close coordination between monitoring, emergency management and emergency response. This field trip will focus on the nature of floodplains in the desert and how floodplain management and flood warning systems work together to support flood safety in both the rural and urban areas around Phoenix. On route to these desert floodplains, participants will learn about a variety of floodplain management techniques implemented to warn or remove people from harm’s way. Stops will include viewing repetitive loss properties, buy-out areas, flashing road warning signals, and a multi-use flood control facility. We will visit a flood warning / decision support center to see how emergency action planning and communications are handled. Participants will come away with a sense of why coordination among emergency managers, weather monitoring, and planned response are critical to the success of keeping people and property safe. Participants will spend time at the Flood Control District of Maricopa County building learning about the flood warning systems and interacting with the flood simulation models.

Historically, seasonal rainfall would regularly flood portions of the Phoenix metropolitan area.  Flood Control Infrastructure designed and constructed by the Army Corps of Engineers, Flood Control District of Maricopa County, and cities were built over a 50 year time frame to provide flood control protection to millions of residents in this urban area. This field trip will focus on various different types of structures - dams, channels, basins, and recreational solutions combined with flood protection.  Participants will learn about the need for Adobe and Dreamy Draw Dams that provide flood protection to north Phoenix, and how the Arizona Canal Diversion Channel protect virtually all of downtown Phoenix from flooding.    Tempe Town Lake, Indian Bend Wash and Grover Basin Dog Park are also stops on this tour.  All of these structures also provide multi-use recreational opportunities.  On route participants will learn the structural and maintenance aspects of these projects and maybe a story or two about the aliens and the history of the projects.
