Wildfire seasons are getting longer and warmer, threatening forests and the water supplies they shield.
Forest restoration, particularly thinning dense stands of timber, can cut back wildfire threat and enhance water availability — however measuring the water advantages of forest administration has been difficult.
That’s why Arizona State University Professor Enrique Vivoni based the startup firm Tributary. Its mission is to give utilities, governments, nonprofits and corporations higher instruments to measure the true water outcomes of forest restoration initiatives.
The technical work is advanced, however the outcomes are easy.
“Clients don’t want to wade through equations,” Vivoni says. “They want to know: How much water will this project save each year? That’s the translation we provide.”
As the ASU Fulton Professor of Hydrosystems Engineering and director of the Center for Hydrologic Innovations, Vivoni has constructed a profession instructing, mentoring and conducting research in hydrology and water assets in arid areas like Arizona.

Tributary grew out of a long time of research and a need to make his experience helpful past academia.
Vivoni teamed up with Zhaocheng Wang, an knowledgeable in distant sensing and AI, and Josh Cederstrom, an knowledgeable in know-how improvement, and the trio is designing Tributary to carry this science to the market.
“This is a full-scale effort to make a real impact,” Cederstrom says. “We are taking rigorous science and making it usable for water managers and utilities.”
Timing issues
Vivoni’s connection to water and forests started in Puerto Rico. As a scout chief, he camped close to a human-made lake surrounded by protected forest.
“That was my entry point to conserving forests for water supply,” he says. “That formative experience led me to pursue college degrees in this field.”
As a graduate scholar at MIT within the early 2000s, Vivoni imagined beginning an environmental tech firm. But the dot-com bust satisfied him the know-how wasn’t fairly prepared.
Two a long time later, new circumstances — together with generative AI, open-source software program, superior distant sensing and Arizona’s historic funding in water research by way of the Arizona Water Innovation Initiative that Vivoni is a a part of — created a completely different, market-ready panorama.
“These pivots created the right moment for Tributary to emerge,” he says.
The launch of the Center for Hydrologic Innovations additionally helped, offering construction for collaboration and linking research to Arizona’s water challenges. Out of this basis, the thought for Tributary started to take form.
The push from idea to firm got here from real-world demand. Utilities like Salt River Project needed higher methods to measure the water advantages of forest thinning.
“That gave us the momentum to launch,” Vivoni says. “Our contribution is to translate peer-reviewed science into outcomes that water managers actually need.”
The give attention to person wants is already paying off.
“The innovative work Enrique Vivoni, ASU and Tributary are doing helps SRP understand the watershed benefits of forest thinning,” says Elvy Barton, supervisor of water and forest sustainability at Salt River Project. “Tributary is providing key watershed metrics and data that allows SRP to clearly articulate the benefits of wildfire resilience and healthy forest projects to our partners.”
Why Tributary?
Healthy forests act like pure infrastructure: storing and releasing water and lowering wildfire threat. Restoration can enhance water provides, however measuring these advantages has relied on tough estimates that miss the complexity of Arizona’s landscapes.
Tributary modifications that. The firm makes use of lidar scans to map forest construction, combining them with information on topography, soils and precipitation to mannequin how thinning timber impacts the water cycle.
“Commercial Earth observation has been advancing for decades,” Wang says. “Advances in AI are pushing this further, enabling products like the first-ever global one-meter-resolution forest maps. The combination of high resolution, low latency, high accuracy and low cost makes this ideal for monitoring changes like wildfire and thinning anywhere.”
As innovation director for Tributary, Wang leads the event of new merchandise and helps switch ASU know-how into sensible instruments by making university-developed research extra accessible, quicker and cheaper — however simply as correct — for purchasers.
“A huge part of my role is about tech transfer, and we are lucky to have a lot of support through ASU. I’m working with Skysong, a technology accelerator, to patent methods developed at ASU and bring them into real-world engineering projects,” Wang says.
For Cederstrom, who serves as technical director for Tributary, ASU’s water startup ecosystem made the leap from trade and again to the college potential.
“Between the Arizona Water Innovation Initiative, the Center for Hydrologic Innovations and SkySong, there’s a whole structure to help researchers move ideas into action,” he says.
The title Tributary displays each hydrology and historical past. In nature, a tributary is a small stream feeding a bigger river, which is an apt metaphor for a startup contributing information to larger sustainability efforts.
It additionally nods to Vivoni’s earlier work on the broadly used tRIBS hydrologic mannequin, refined by a world research neighborhood for greater than 20 years and now used as a foundation for Tributary’s work.
Looking forward
Though primarily based in Arizona, Tributary’s ambitions prolong far past. The want for more healthy forests and smarter water administration is world.
“In Arizona,” Vivoni says, “we’re piloting solutions that can scale not only across the western U.S., but for the world.”
That scaling relies on folks as a lot as instruments. Vivoni emphasizes the function of scholars who carry ahead the science and abilities honed at ASU. Tributary is one profitable instance of a larger effort at ASU to develop a water know-how startup ecosystem in Arizona.
“This is about the human capital we’re developing,” he says. “I’m leading Tributary now, but over time I’ll step back and serve more as an advisor as others take it forward.”
Tributary represents greater than a startup story. It’s an instance of how universities can export information to the world. For Arizona, it means turning research into sensible options for water and forest administration.
“In a sense, what we’re exporting is knowledge,” Vivoni says. “It’s taking what universities do best— long-term, rigorous science — and making it usable outside the campus walls.”
