Modelización de la calidad del agua del estero Guaygí, cantón Quevedo, provincia de Los Ríos, año 2018 - 2019

The present study evaluated the water quality of the Guayji estuary "Quevedo of the province of the rivers", the surface water quality was monitored during the months of August and November, the main objective of this investigation was model the incidence of Dissolved Oxygen (DO) and Biochemical Oxygen Demand (BOD) the estuary. In order to meet the following specific objectives. (one). Determine the morphological hydro characteristics of the Guayji estuary. (two). Characterize the water quality of the Guayji estuary. (3). Model the water quality of the Guayji estuary with the Streeter-Phelps model. (4). Simulate with WASP computer programs the water quality of the Guayji estuary. The characterization of the physicochemical parameters of water quality was carried out, which they had: Biochemical oxygen demand (BOD), dissolved oxygen (DO), hydrogen potential (pH), temperature (oC), and electrical conductivity (CE). Seven sampling points were established, which were: section 1, section 2, section 3, section 4, upstream of section 1, the initial download of section 1, a tributary beginning of section 4, with 8 biweekly sampling campaigns during the months August, September, October, November, considered in the dry season. The applied mathematical model was based on the Streeter-Phelps equations, which allowed the water quality of the Guayji estuary to be modeled to obtain the BOD and OD profiles, where in the first stay the constants were obtained by applying the respective mathematical equations, to then calibrate the kinetic constants of reairration (Ka), deoxygenation (Kd) and total removal of the BOD (Kr) using statistical software Statgraphics using the Monte Carlo simulation tool, obtaining 10,000 possible variations of the kinetic constants. Finally, the simulation of water quality was carried out by implementing the QUAL2K program, entering the required hydrodynamic information of the stream and the calibrated constants. Key words: Dissolved Oxygen, Biochemical Oxygen Demand, Water Quality, Streeter-Phelps, calibration, kinetic constants, Monte Carlo simulation, Qual2k.
