Abstract

ARROYAVE GOMEZ, Diana Marcela et al. STUDY OF THE WATER QUALITY MODELING OF THE SINÚ RIVER, COLOMBIA. Rev. ing. univ. Medellín [online]. 2013, vol.12, n.22, pp.33-44. ISSN 1692-3324.

In this work a water quality modeling study of the Sinú river, Colombia, is presented in the segment from Urrá hydroelectric generation power plant to Caribbean sea mouth using the QUAL2KW model which incorporates the PIKAIA genetic algorithm that allows the calibration of the kinetic constants for its application to any waterbody. Specifically, the study shows the methodology used for the hydraulic characterization, the segmentation of the stream and the use of the Monte Carlo sampling method to determine the most sensitive water quality parameters and to demonstrate that the QUAL2KW model could not be calibrated for the Sinú river with the available filed information, because several combinations of the parameters produced equally optimal solutions.

Keywords : Genetic algorithm; QUAL2KW; Monte Carlo method; water quality modeling.
