The Philippine National Hydrological Model is the first national-scale hydrological model of the country. Its primary purpose is to quantify components of the hydrological cycle at the national level, with model outputs of Spatio-temporal patterns of: • precipitation • evapotranspiration • surface runoff • river flow • groundwater recharge • groundwater flow The model has been developed using a version of the macroscale hydrological modelling software Variable Infiltration Capacity (VIC), into which a gridded groundwater model has been added so that it simulates the integrated surface water and groundwater system. The model has been constructed using openly available global datasets and calibrated against local observations, principally of river flows. The resulting modelling framework provides a means to develop understanding of the water resources across the Philippines and aims to support future national water resources planning. We present a summary of the results of the model using monthly district averaged components of the water cycle. We also briefly describe some of the potential benefits of the continued development and improvement of the model and of its future use.
