Tabios, Guillermo Q. III
Ph.D. Civil Engineering
Engineering Sciences and Technology
Dr. Guillermo Q. Tabios III is recognized for his significant and outstanding contributions in the field of civil engineering, specifically in hydrology, hydraulics and water resources systems engineering. His pioneering work on two-dimensional hydraulic modelling using finite volume method (FVM) has been applied to river restoration project in Kissimmee River in Florida. Then, Dr. Tabios extended the FVM model to include sediment and water quality transport and applied to various rivers, reservoirs and lakes in the Philippines for flood control, reservoir sedimentation and sediment flushing operations, dam break studies for emergency preparedness plan, salinity intrusion and contaminant transport studies, among others. He also developed a pipe network model with optimization for the Metro Manila water distribution system for detection, surveillance and quantification of non-revenue water due to pipe leakage or pilferage; for planning and expansion studies of optimal pipe network; and for normal operations of the pipe distribution system. His optimization-simulation model studies include optimal water allocation of competing water uses of the multipurpose Angat Reservoir, hydropower optimization studies of the Ambuklao, Binga and San Roque Reservoirs in Agno River; project sequencing and staging alternative reservoir system configurations in the Kaliwa-Kanan-Agos River Basin to augment Metro Manila’s water supply. He authored the book “Water Resources Systems of the Philippines: Modeling Studies” published by Springer International.
