TITLE: Estimating Crop Water Use from Space

There is an ever-increasing demand for water to support expanding agriculture. This demand is often met by groundwater, which has a negative impact on both its future availability and its quality. Such is the case in Saudi Arabia, where the predominant water supply is from fossil aquifers. Due to the spatial scale of agricultural sites, it is impossible to have local installations to monitor all the variables involved in crop production. Satellite-based sensing approaches can be used to provide the needed detail for farm-scale monitoring, allowing local to global scale estimation. Using such data, it is possible to estimate the crop water use, facilitating improved water management in agricultural systems, providing insight into the health of farmlands, and offering the capacity to mitigate aquifer overexploitation to ensure sustainable supplies into the future.

Bruno received his BSc from Monterrey Institute of Technology and Higher Education (ITESM) in Mechatronics Engineering. He received his MSc degree in Environmental Engineering from King Abdullah University of Science and Technology and is currently pursuing a Ph.D. under the supervision of Professor Matthew McCabe. His research work is in evaporation estimation using remotely sensed imagery.

TITLE: Low Temperature Seawater Desalination using Multi Effect Distillation and Adsorption (MEDAD) Hybrid Cycles

To investigate the impact of using low temperature (or grade) thermal energies in desalination processes, fuel allocation analysis on derived energies (electricity and steam) from the dual purpose plants conducted for evaluating the energy consumption. The exergetic method of fuel allocation is applied to ensure direct analysis of useful energy potential and assess the environmental sustainability of the process. In line with the energy consumption analysis, study on hybridization of thermal processes are on-going to maximize the thermodynamic synergy and utilize the low temperature energy in seawater desalination. Adsorption desalination (AD) cycle combined with Multi-effect Distillation (MED) allows lowering the temperature limitation (30C, ambient) of MED last stage to 5C.

SON, Hyuk Soo is a Ph.D. candidate in Water Desalination and Reuse Center, and his advisor is Professor Kim Choon NG. He completed his M.Sc. degree in chemical & biological engineering at Seoul National University, Rep. of Korea. In prior to starting his Ph.D. in KAUST, he worked in Korea, Jordan, and Yemen for 5 years as a program manager and senior researcher in governmental institutions of Korea.
