\n\nCebu, with its growing development and increasing demand for water, needs tools and inputs to efficiently understand and manage\nits water resources. Rainfall runoff models were developed to model surface runoff which may be used to assess water availability.\nSoil Conservation System (SCS) Runoff Curve Number (CN) method predicts runoff based on an empirical curve number for\nungauged watersheds. This study aims to estimate the amount of runoff for the catchments of Cebu Island using the SCS-CN\nRunoff technique. The data needed for the application of the method in this study were rainfall distribution data, land use\/land\ncover and soil texture for curve number assignment, LiDAR DEM for the delineation of the catchments, and supporting runoff\nmeasurements from a different runoff estimation model for assessment of the results. The collected data were prepared by assigning\nthe mean statistics of the rainfall distribution and the composite curve number for each catchment using Geographic Information\nSystem (GIS). The calculation of the runoff was also done using the same framework. Maps representing Cebu Island\u2019s catchments\u2019\nrunoff estimates were produced. Since observed runoff data were unavailable, the results were verified by comparing the SCS-CN\nestimated runoff to the results of a physically-based distributed hydrologic and hydraulics modelling software, FLO-2D. The SCSCN estimations were found to coincide with the FLO-2D runoff estimates based on various statistical assessments. Although the\nresults may have higher uncertainties due to the unavailability of observed runoff data, the SCS-CN Runoff method provided\nrelevant results to that of a complex simulation model. Thus, the method may be applied to estimate runoff of ungauged catchments\nof Cebu Island, the results of which could provide relevant information for water resource management.\n\n<\/p>\n","protected":false},"excerpt":{"rendered":"
