A service-oriented architecture for ensemble flood forecast from numerical weather prediction
Flash floods in mountainous river basins are generally highly destructive, usually causing enormous losses of lives and property. It is important and necessary to develop an effective forecast method to prevent suffering flash flood disasters. This paper presents a general framework of a service-oriented architecture (SOA) for ensemble flood forecast from numerical weather prediction (NWP), taking the advantages of state-of-the-art technologies, e.g., the high accuracy of the NWP, the high capacity of cloud computing and the interactive inherence of Web Service. A more accurate prediction for atmospheric condition and meteorological phenomena in the near future, e.g., the rainfall, can be obtained from the NWP. Then the predicted rainfall drives the hydrological model to run automatically on the cloud. Judging from the results of computed streamflow and the flood control requirements offered by different users, warning information of flash floods will be generated for potential sufferers and then sent to them as soon as possible if needed. Moreover, by using Web Service in a social network, users can acquire such warning information on the client as well, and make their decision whether they will prepare for the possible flood disaster. Along with the real-time updates of the NWP, the results of computed streamflow would be refreshed timely, and the latest warning information would always be available. So far, the SOA has played an important role in a wide variety of applications, and it is regarded as a feasible way of establishing the ensemble flood forecast system by using the NWP. After being put into practice, it would be useful for preventing or reducing the losses caused by flash flood disasters in mountainous river basins.
