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.

Modelling the Far-field Effluent Plumes from a Multiport Diffuser
Author : Anton Purnama
A far-field mathematical model for effluent discharge through a marine outfall with multiport diffusers is developed using a two-dimensional advection-diffusion equation based on a flat seabed that incorporates the effect of a tidally oscillating flow. Using the asymptotic approximation of the analytical solutions, the maximum diffuser-induced shoreline's concentration is formulated to predict the long-term potential impact of sea outfall discharge in the coastal waters and to measure its effectiveness over the single outfall discharge. The result shows that a long sea outfall with a perpendicular line diffuser (to the flow direction) is capable of thoroughly mixing and diluting the discharge effluent plume into the far-field.
