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.

A numerical study of the effects of vegetation patternson wetland performance

ABSTRACT
Conceptual wetlands of simple geometry and randomly distributed vegetation fields with imposed statistical properties
(stem density average, variance and correlation length) were generated to assess their performance in the removal of
contaminants. The hydrodynamics was solved using a two-dimensional depth-averaged model where flow resistance is
generated by both bed friction and stem drag. Mass transport was solved using an advection-dispersion model with a
decay rate dependent on the local properties of the vegetation field. Wetland performance was found to depend primarily
on average vegetation density, but an increasingly significant effect on mass removal is observed as stem density
variance and correlation length increase.
