Modelación de un vertimiento doméstico sobre una corriente hídrica aplicando el modelo de Streeter y Phelps

Abstract

The present study evaluated the assimilation capacity of a domestic discharge on a water current applying the Streeter and Phelps model. For this the quality of the resource was determined through the Water Quality Index-ICA proposed by the IDEAM, besides the hydrodynamic processes and their purification capacity were evaluated. Applying the model to a specific stretch of the Mensulí, according to the behavior of OD and BOD resulting, the shedding begins its recovery at 0.89 km, but its complete assimilation is given to 17 km. Bearing in mind that there are more downstream discharges, it is important that all users of the stream commit themselves to mitigate the environmental impact produced on the resource. The case study allowed to verify that the Streeter and Phelps model is a valid tool to evaluate the assimilation of an effluent, as well as for the decision making based on the recovery of the water resource, so it is a methodology that can be used in environmental procedures.
