Conjunctive Water Management (CWM) is the process of using water from multiple sources for consumptive purposes within a sustainability framework. The planned CWM of all waters has the potential to offer major benefits in terms of economic, social, and environmental outcomes through improved efficiencies and sustainability of water resources. In this WRRC Water Webinar, Hanson will discuss how adopting a planned approach results in the greatest potential for the optimal capture, storage, abstraction, and reuse systems of all water sources, which results in a sustainability framework that encompasses the monitoring, analysis, and management of all the water, all the time, everywhere. New “Smart-Valley” monitoring networks and Integrated Hydrologic Modeling (IHM) tools can now be used to create a more holistic CWM sustainability framework that needs to be combined with new governance and financial support.

Randall Hanson was a lead USGS research hydrologist for over 38 years developing hydrologic methods and water-supply analysis of regional watersheds nationally and internationally. His research includes development of the integrated hydrologic models across the USA and internationally and leading the development team for the One-Water version of MODFLOW used for conjunctive water management (CWM), climate-change adaptation, and sustainability analysis, such as SGMA in California. Now the president and lead hydrologist for One-Water Hydrologic, LLC, Randall is helping scientists and engineers use the new One-Water code for their food and water-security analysis and assessing climate variability relative to CWM sustainability.
