This paper presents a new marine water quality forecasting system for real-time and short-term predictions. The forecasting system comprises an integrated catchment-coastal model and a database management system. The integrated model is validated in an Irish catchment-coastal system using hydrodynamic and water quality data. The forecasting system was then used to provide short-term and real-time forecasts of Escherichia Coli (E. coli) and Intestinal Enterococci concentrations (IE) in the near-shore coastal waters of Bray, Ireland. Two hind-cast scenarios were simulated: 5F in which predictions were based on rainfall forecasts only; and I-5F where forecasts of 5F were improved by incorporating real-time data. Results indicate that predictions of E. coli of scenario I-5F are improved. Also predicted IE concentrations by Scenario 5F were comparably higher than the I-5F predications, but due to the wide scatter of observed IE concentrations, the superiority of one scenario over the second could not be definitively determined.

Keywords: Real-time forecasts; integrated model; marine water quality; three-dimensional hydrodynamics; MIKE; catchment modelling


The work has been funded by an INTERREG 4A (Ireland and Wales) project. Technical support on the use of the model was provided by DHI (UK and Denmark). Thanks are extended to Dr Ahmed Nasr, Dublin Institute of Technology (DIT) for his help and useful discussions and to Mr Garrett Keane, DIT, for the assistance in the calibration of the tidal constituents of the MIKE Global model. The authors wish to acknowledge the help and information provided by Irish EPA, Bray Town council, Wicklow County council and the staff of Shanganagh Treatment works.

Latest presentations confirmed for the MIKE by DHI Symposium on 13th May 2014

Clifford Williams (Modelling and Forecasting, Environment Agency) has kindly agreed to give a talk on 'Real Time Flood Forecasting in the Environment Agency'. In the context of the recent winter floods and storm surges, the presentation will focus upon flood forecasting systems used by the Environment Agency, how the Environment Agency interfaces with the Met Office, the hydraulic models used by the Environment Agency (incl. MIKE 11) and how the service is delivered (e.g. to Flood Resilience Teams).

Since 2002 DHI has operated an early warning system for
bathing water quality. It all began in Copenhagen when
the harbour bath was a reality, but since then the forecast
system has spread to a number of Danish and Swedish
municipalities and most recently a New Zealand municipality
has also initiated a similar system. The advantages of the
bathing water system are manifold: 1) It complies with the
EU bathing water directive, 2) it protects the public from
getting exposed to sewage water and 3) it allows the
municipalities to proactively monitor and manage the
bathing waters.
Adam Leonard-Williams (Senior Metocean Scientist, Met Office) will also be giving a presentation on 'Just how severe was the 2013/14 winter and how did the Met Office wave model perform?'. These topical presentations will be followed up within the training sessions on the second day of the conference by seminar style briefings on our own innovative forecasting technologies: -

  • Introduction to MIKE CUSTOMISED Real Time – monitoring, flood forecasting, early warning and efficient operational controls for urban and riverine environments – comprising a live demonstration of the technology, selected relevant case studies and Q&A session.
  • Introduction to a MIKE CUSTOMISED Bathing Water Forecasting System, for example (in Danish but self-explanatory!). The presentation will introduce the bathing water forecast system and the data / models needed to build a similar system. It will be followed by Q&A session.

There is still time to register for this free event! Please visit the Symposium website at or register now at

The world's water consumption rate is doubling every 20 years — twice as fast as the population growth rate. By 2025, water demand will exceed supply by 56%.

The critical need for water to sustain all aspects of human activity has driven us to inhabit floodplains and deltas close to rivers. Today, 82% of the global population lives in these areas and is exposed to a high risk of flooding.

We constantly strive to develop a robust understanding of the physical water environment as a precursor to any analyses influencing decision-making. Applying state-of-the-art modelling technologies and analytics ensures that we achieve this. We work closely with our clients and stakeholders to appreciate the water management issues that may affect their project outcomes. In so doing, we develop solutions that are appropriate, cost-effective and environmentally responsible.

Read our Newsletter to find out more about the work we have done in the field of 'Surface and groundwater' through few of our highlighted stories. If you have any questions or would like to know more, feel free to drop us a line. Read more >>>
