Our solution delivers a fully operational flood forecasting system for each of the catchments. As part of the development of the warning systems we assessed the various inputs to the system and advised on both the accuracy and reliability of these sources. The forecasting systems are automatically linked to real-time data sources, which include rainfall (rain gauge, observed radar and forecast numerical predictions) and water level gauges. Incoming gauge data is automatically quality checked for data inaccuracies and infilled as required.
The forecasting system produces forecasted water levels and flows at thousands of locations along the rivers and on the floodplains, allowing flood warnings to be targeted at specific people. Warning locations include schools, hospitals, mosques and villages, as well as key points in rivers.
The forecasting system has automatically scheduled flood forecasts with forecasts being issued several times each day. All key results, including rainfall, water levels and flood maps are provided to the national flood control centre, where it is analysed and then disseminated to all relevant authorities. Evacuation and emergency response can then be organised in a timely fashion, saving people from flooding.
