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.

Multiple event analysis of fine sediment pollutant transport through a sustainable urban drainage system
rch gap in the analysis of this multiple event sediment deposition, distribution and pollutant flushing
efficiency through Sustainable urban Drainage Systems (SuDS). Past study of SuDS efficiency in urban pollutant
conveyance has focused on event and snapshot analysis. Recent studies have assessed event based suspended solid
mitigation by SuDS assets, while sedimentation research considers deposition over multiple annual periods within wet
(blue) assets. The functionality of ephemeral or ¡®green¡¯ SuDS assets and treatment trains comprised of both blue and
green systems is less well understood over the longer term. The novel tracing technique was an in-house developed REO
La tag. Field data collected were rainfall, tag concentration, TSS and deposition mass. Conclusions specific to the case
study are: (i) resuspension and transport of material within the SuDS treatment train occurs for a minimum of 16 weeks; (ii)
linear wetland assets general outperform alternative SUDS assets in terms of TSS mitigation and deposition; (iii) using a
multiple event analysis highlights significant under-performance of SuDS assets against design capacities.Form Required :
