Sažetak
Infrastructure management system comprises the design, construction, operation, monitoring and maintenance of roads and bridges. For roads adjacent to streams and bridges over water, an infrastructure management system should also consider issues of flooding and scour hazards. In this paper we present a case study of a new flood early warning system as valuable tool for safer management of roads and bridges over water. Besides existing gauges, the new hydrological monitoring system also comprised the development and installation of new weather and water level gauging stations which provide information on rainfall, soil moisture and air temperature in the area and water level at bridges in real-time. The new flood early warning system is developed around the rainfall-runoff model on contributing catchments and provides information on the existing and forecasted water levels and discharges on dedicated locations, such as bridges and low-laying roads. The deployment of flood early warning system required a calibration of hydrological model, automatization of data manipulation to/from hydrological model and forecast verification. The resulting water levels and discharges on dedicated locations are obtained for measured rainfall data (flood nowcasting) as well as for rainfall predictions (flood forecasting). Information from this system can be seamlessly included in the decision processes at different stages of infrastructure management, including the construction stage, operation and monitoring stages. One of the key aspects is the dissemination of warnings in advance of potentially hazardous events. The study of flood early warning system is given in a case of a new Bandon Flood Forecasting System in Ireland by using Delft FEWS platform. The unique feature of the Bandon system is the scour depth prediction at bridges on the basis of the flood forecasts.
