Center for Hydrologic Innovations

Revolutionizing water measurement, modeling and prediction

The Center for Hydrologic Innovations (CHI) harnesses the power of data and visualizations from observational platforms and modeling systems to inform short-term water decisions and plan for alternative water futures. Nothing short of a transformational approach is needed to modernize how water is monitored, analyzed and predicted.

CHI is leading to the creation of new technologies, fostering entrepreneurship and job creation through startup companies and helping train personnel at partner organizations in the water and environmental sectors, including the Central Arizona Project, Arizona Department of Water Resources, Salt River Project, Arizona Department of Environmental Quality and private sector firms.

Innovation and impact

CHI is revolutionizing water measurement, modeling and prediction and providing data necessary to identify critical risks, vulnerabilities and capabilities in hydrologic systems. The Arizona Water Observatory is deploying state-of-the-art technology to fully map, monitor and model all of Arizona’s water supplies.

Streamflow Presence and Flood Hazards

Dr. Vivoni and Dr. Wang developed a new approach to using Earth-observing satellites to detect the presence of flowing water in arid and semiarid rivers in California and Arizona. This project uses small commercial satellites called CubeSat, typically the size of a shoebox, that can orbit the Earth and even travel in deep space. In contrast with traditional methods based on labor and time intensive ground-based field surveys, this approach is allowing the team to assess streamflow regimes of rivers across large arid and semiarid regions at very high spatial and temporal resolution.

Climate Change and Water Supply

In collaboration with the Central Arizona Project and 14 other water management agencies, ASU’s team of researchers developed the Colorado River Basin-Scenario-Explorer. The Scenario Explorer is an online visualization tool with the ability to simulate scenarios like droughts and forest disturbances, enabling users to explore and understand the impact of climate change in the Colorado River Basin. Future improvements to the project include updating the water visualization tool so that it auto-populates with real-time data and modeling information from NASA and other agencies. The use of satellite observations and hydrologic modeling will greatly improve water resource decisions and management. Learn more.

Forest Health and Water Resilience

ASU and Salt River Project are working together to understand the effects of forest thinning on the hydrologic cycle. The Triangulated Irregular Network-based Real-time Integrated Basin Simulator was used to provide insight into the effects of forest cover reduction on the hydrologic response of watersheds in the Salt-Verde River system. Strategic forest thinning efforts help reduce the threat of catastrophic wildfire and could be a possible solution to protecting our water supplies. Learn more.
