Resource Title | Modeling nutrients along Bued River with point sources of pollution |
Date Issued | 20 August 2018 |
Abstract | A study of University of Cordillera on identification of sources of pollution along the Bued River showed that about 82% of the pollutants came from residential community and livestock. These sources released excessive amount of nutrients to the river which caused depletion of dissolved oxygen. This study aims to determine fate and transport of nutrients along Bued River using WASP EUTRO by considering point and nonpoint sources of pollution. Concentration of nutrients on established sampling points along the river was collected monthly from July 2014 to January 2015 which was used in calibrating the generated WASP EUTRO model. Comparison of concentrations of nitrates and phosphates between observed and modelled data has PBIAS value of -0.022 and -0.173, respectively. Hydrological components of the model were supplied by Bued watershed model from HEC-HMS. DAO-2016-08 water quality guidelines were used in assessing the nutrients concentrations of the river segments. Bued River classification is Class C which has maximum nitrate and phosphate concentration of 7.0 mg/l and 0.5 mg/l respectively according to Philippine water quality standards. Nitrate concentration for majority segments of the river were less than 7.0 mg/l while phosphate concentrations for majority of the segments on upstream part of the river up to Liwliw Tributary were more than the 0.5 mg/l limit. Despite the phosphate concentration above the standard, dissolved oxygen concentrations for all segments of the river had passed the standard. |
