IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

Cormix model aplication in time series for different scenarios of effluent types
Author : PASSOS G.J.S.(1) & BLENINGER T.(2)
ABSTRACT
This work will demonstrate the effects that different effluents and discharge configurations have on marine waters. The
method uses CORMIX, a hydrodynamic modeling software capable of predicting the geometric characteristics and
dilution of the initial mixing zone. The model was run in a time-series mode, representing one month data and changing
the ambient and effluent characteristics. This series was simulated by CorTime, a post-processing submodule of
CORMIX, for nine study scenarios. There were three effluent types (treated sewage, cooling water and industrial effluent)
discharged by three different discharge configurations (multiport diffusers, submerged single pipe and open channel with
free surface). The best dilution occurred with the multiport diffusers. The other discharges presented dilutions under 100,
with lower efficiency, thinner plumes (less than 2.4 m), concentrated on the surface (treated sewage) or on the sea
bottom (industrial effluent). These cases need greater investment in effluent treatment, they cause greater environmental
impact, visual aspect concerns on the surface and the ecosystem on the sea bottom. The plume of the onshore channel
discharge configuration always reached the coast, thus having the potential of problems related to bathing water quality.
