    Water quality model-based methodology to assess assimilative capacity of wastewater discharges in rivers by F.M. Torres-Bejarano, M. Verbel-Escobar, M.C. Atencia-Osorio

    Published 2022-10-01
    “…Higher concentrations of water quality parameters were mostly found in the dry season since lower velocities and river flows promote less pollutants mixing and dilution processes.CONCLUSION: The model spatiotemporal simulations showed the effect of the wastewater discharges on the Sinú River assimilative capacity and made it possible to find those scenarios where water quality parameters exceeded the reference limits, becoming an essential tool for water management and the development of strong water quality objectives by stakeholders and environmental authorities.…”
