Presenter: | Alex Wood, P. G. As a hydrogeologist and professional geologist (Arizona), Alex Wood combines his extensive knowledge of western US geological provinces with geochemical and hydrological analysis techniques to evaluate a variety of water resource issues. Alex has a B.S. and M.S. in Geology from Northern Arizona University. Through his time as a researcher and environmental consultant, he has gained experience and expertise in watershed restoration, wetland & stream rehabilitation & restoration, post-fire hydrology, regional groundwater studies, evapotranspiration (ET) modeling, and more. Currently, Alex serves as the Principal Hydrogeologist at Natural Channel Design Engineering in Flagstaff, AZ. |

| Abstract: |
The hydrogeology and hydrology of aquifer systems and plateaus in Northern Arizona, specifically the Grand Canyon ecoregion, are unique based on a variety of factors. First and foremost, the emplacement and incision of the Colorado River through Grand Canyon dictates surface water drainage patterns and where regional groundwater discharges in the form of springs. Secondly, geologic units and structures (such as faults, folds, etc.) have regional variances that greatly impact the quantity and quality of groundwater. Thirdly, aside from the Colorado River and spring fed creeks within Grand Canyon itself, there is virtually no perennial surface water flow in creeks or streams regionally due to stream capture by extensive and widespread karst development (sinkholes, caves, conduits, etc.). Regionally, the Kaibab Plateau and San Francisco Mountain near Flagstaff, AZ provide all surface water recharge to these regionally important aquifer systems. This talk will broadly discuss Grand Canyon geology, theories and studies regarding Grand Canyon's origin and emplacement of the Colorado River, unique Grand Canyon hydrogeology research such as on-going dye tracing studies, threats to surface water and groundwater resources, regional restoration work, and other locally interesting hydrogeology.
