Research & Outreach Overview:
Our research group focuses on developing and disseminating scientific knowledge, practical recommendations, and tools for sustainable urban and agricultural water resources management. Our approaches include field research trials, laboratory analyses, and computer modeling, with the goal of identifying opportunities for synergy between research and outreach activities. Our current research themes include water conservation, autonomous landscape irrigation management, soil hydrology, and precision farming. We also work on applications of advanced data acquisition and mining techniques, including remote sensing, GIS and machine learning.
On-going Projects:
|
Establishing real-world water use and irrigation cooling benefits baselines for 18 landscape species in inland southern California (2023-2024)
|
PI: Amir Haghverdi
Sustainable urban landscape irrigation under a changing climate in semi-arid inland southern California requires identifying drought/heat tolerant plant species and irrigation management scenarios that maximize water saving while minimizing the urban heat island effect. This project will address these major knowledge gaps for moving toward sustainable landscape irrigation management in the region. This project also creates a pathway toward autonomous efficient irrigation management in our smart cities in the future, where smart controllers will apply the right amount of water to each plant species.

Development of a Novel Photochemical Water Reuse Technology for Urban Agriculture Irrigation and Food Production (2022-2023) |
PI: Haizhou Liu | Co-PI: Amir Haghverdi
This project aims to improve agriculture sustainability by developing an innovative photochemical treatment for recycled wastewater irrigation and evaluating downstream risk using a field irrigation research trial.
|
Developing evapotranspiration based irrigation and water conservation recommendations for multiple groundcover species in inland southern California (2021-2024) |
PI : Amir Haghverdi | co-PI: Don Merhaut
This project will promote the adoption of science-based plant factor information to develop irrigation best management practices to sustain the desired landscape quality using minimal water.
