Dr. Sayde believes that sustainable management of our agricultural and natural systems requires a paradigm shift in the way we manage our water. This paradigm shift will be largely driven by a new generation of physically based models and tools that enable continuous monitoring of our environment over wide range of temporal and spatial scales. Dr. Sayde’s research is focused on developing and employing advanced models and sensing systems to quantify water and energy movement across the soil-plant-atmosphere continuum from individual plants, to field and watershed scales. His objectives are to employ the ultra-high density of initial and boundary conditions measurements across the landscape to i) understand the underlying physical processes and the interaction between water, atmosphere, soil, topography, and vegetation, and ii) formulate engineered solutions to agricultural water management challenges that optimize economical return of water and minimize its adverse environmental impacts.
Areas of interests include:
- quantifying and understanding physical processes that control energy and water movement through the soil-plant-atmosphere continuum at 0.25-10,000 m scales
- development of distributed environmental sensing systems
- design and management optimization of irrigation systems
- development of physically based agricultural water management models
