BETTER FORECASTING AND DIRECTION
Flood Control 2015 put together all the different pieces of the jigsaw, producing a single whole by establishing smart links between tried and trusted systems. This makes our forecasting more reliable. Traditionally, meteorology, hydrology, geotechnical engineering and crisis management operate separately. This means that margins of error and uncertainties accumulate. Linking the different fields leads to a major leap forward in reliability. That makes forecasting more accurate in terms of what is going to happen, and how probable future events are.
Consequently, the value of forecasts of water levels and wave heights depends on the quality of the forecast. This is a question of the accuracy and reliability of the data. Real-time decisions can then be taken on the basis of the predictions. This project revolves around the development of techniques and methods for improving forecasts and taking sounder decisions
