With the aid of the distributed biosphere hydrological model WEB-DHM, this study investigates the ENSO influence on the 1982-2000 hydrological properties of the Pantabangan-Carranglan Watershed, Philippines. First, the model is evaluated with the 19-year monthly observed discharges. Second, time-series trends of five hydrological properties (observed rainfall and discharge as well as simulated evapotranspiration, surface and root zone soil wetness) are considered focusing on the influences of El Niño and La Niña phenomena on these properties. Reversals in the anomalies of the hydrological properties occur for El Niño and La Niña.
