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.

Integrated Water Management Solutions from Cloud to Coast: Application to Ribble Basin
Author : Brian A. Boye, Roger A. Falconer and Roger A. Falconer
This paper reviews the traditional approach of linking models to cover integrated water management from the upper reaches of catchments through river basins, into estuaries and the coastal\marine environment. It highlights some of the de?ciencies in the approaches currently being adopted in many non-integrated studies, where arti?cial boundaries are included in the system and then highlights the need for a more integrated conceptual approach. A case study is discussed, namely the non-compliance of bathing waters along the Ribble Estuary from riverine inputs, with the inputs arising from Waste-water Treatment Works, outfalls and drainage systems. A more integrated approach was applied to this estuary, with re?nements to the arti?cial boundaries. Both hydrodynamic and solute transport processes in 1-D and 2-D domains of this estuary were modelled for a wet event in June 1999. The kinetic decay process representation included the impacts of salinity, solar radiation, turbidity and water temperature. Solutes modelled included faecal coliform, temperature and salinity. From the resulting coliform levels in the integrated model, it was concluded that a better calibration of the model could be obtained by including the e ects of cloud cover on decay rates and a more complete inclusion of agricultural or urban run-o . The more integrated approach therefore results in a better inclusion of the physics, giving improved model predictions. Hence better decisions can be made when considering investment strategies, appropriate for various treatment options and solutions in the river basin upstream.
