“…However, such approaches can significantly simplify a number of processes concerning sources, transport, survival and transformations of harmful contaminants (e.g., see in [10]). The number of additional terms and associated parameters required to account for transport and fate processes exacerbate non-identifiability and equifinality issues which are a common problem for complex integrated models [16]. To develop a more robust understanding of health risks posed by urban flood waters, detailed information is required concerning individual processes associated with sources, transport pathways and life cycles of pathogens from sewer/drainage networks to surface flows and on urban surfaces.…”

Surcharging urban drainage systems are a potential source of pathogenic contamination of floodwater. While a number of previous studies have investigated net sewer to surface hydraulic flow rates through manholes and gullies during flood events, an understanding of how pollutants move from sewer networks to surface flood water is currently lacking. This paper presents a 3D CFD model to quantify flow and solute mass exchange through hydraulic structures featuring complex interacting pipe and surface flows commonly associated with urban flood events. The model is compared against experimental datasets from a large-scale physical model designed to study pipe/surface interactions during flood simulations. Results show that the CFD model accurately describes pipe to surface flow partition and solute transport processes through the manhole in the experimental setup. After validation, the model is used to elucidate key timescales which describe mass flow rates entering surface flows from pipe networks. Numerical experiments show that following arrival of a well-mixed solute at the exchange structure, solute mass exchange to the surface grows asymptotically to a value equivalent to the ratio of flow partition, with associated timescales a function of the flow conditions and diffusive transport inside the manhole.

“…Many studies have confirmed that heavy metal residues in contaminated aquatic habitats accumulate in the bodies of microorganisms, aquatic plants and animals and ultimately enter human bodies via the food chain [7][8][9][10][11][12][13][14][15][16][17]. The contamination of fresh water by heavy metals causes great hazard on the ecosystem and serious health risks [3,4,[18][19][20]. Therefore, heavy metal pollution in freshwater systems is a serious environmental problem and widely investigated at present [18,[21][22][23].…”
