The study, called «Modeling the effects of adopting agroforestry on basin scale
surface runoff and sediment yield in the Philippines,» uses a computer - based Soil and Water Assessment Tool (SWAT) to
simulate the effects of different land uses on watershed hydrology and the ecosystem services provided by the Gabayan watershed.
The
simulated data includes snow water equivalent, soil moisture,
surface runoff (
runoff), subsurface
runoff (baseflow), and actual evapotranspiration for a region covering the Peace, upper Columbia, Fraser and Campbell River watersheds.
