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 Fate and Transport of Faecal Bacteria in the Ribble Estuary, UK
Author : Guanghai Gao, Roger A. Falconer and Binliang Lin
The decay rate of faecal bacteria is influenced by many environmental factors, such as, sunlight intensity, temperature, salinity, sediment concentrations etc, however, it was normally treated as a first order constant process in hydro-environmental model studies The paper detailed a numerical model developed for faecal bacteria fate and transport in receiving waters in a coastal basin in the UK. Faecal coliform, used as the indicators, were numerically modelled using a hydro-environmental model. Dynamic decay rate, which includes effect of salinity, temperature and light intensity were used in current study, compare to most other studies constant decay rate were normally used. In particular, the numerical model used in this study includes the effects of sediment on bacteria transport processes in surface water. This model was first validated by comparison with the field measurements of faecal bacteria concentrations. The model simulations agreed well with the observation data.
