ASU and University of Arizona researchers are making progress on more effective and efficient ways to water and grow trees that provide shade to shield much of the state’s desert landscapes from the increasing number of days when temperatures hit 100 or more degrees Fahrenheit. Though not specified in the broadcast interview, contributors to the research include Associate Professor Zhihua Wang and Assistant Professor Tianfang Zhu in the School of Sustainable Engineering and the Built Environment, part of the Fulton Schools. Wang’s work includes urban climate modeling, land-atmospheric interactions, landscape and infrastructure management, and urban environmental sustainability. Zhu’s research focus includes simulation of groundwater flow and solute transport, uncertainty quantification and applications of machine learning in hydrology.
