Environmental Hydrology Laboratory

A new study led by Environmental Hydrology Laboratory researcher, Mr. Kean Michael F. Cabigao, has been published in the Hydrological Sciences Journal – the official journal of the International Association of Hydrological Sciences (IAHS). 

The research entitled “Evaluating gridded climate datasets for hydrological assessment of data-scarce watersheds in the Philippines using the SWAT model” addressed a gap regarding the influence of gridded climate dataset selection in modelling Philippine watersheds using the Soil and Water Assessment Tool. 

The study provided a process-based evaluation of multiple gridded climate datasets and showed that rainfall datasets remain the primary control on basin-scale hydrologic assessments. The results also revealed that model parameters represent climate forcing-dependent behaviours rather than universal physical constants; thus, parameter transferability is constrained by how forcing reflects basin climatology.
