CONSTRUCTION OF A REAL-TIME INUNDATION FLOW ANALYSIS SYSTEM AND DIRECTIONS OF ITS PRACTICAL USE

Abstract

For making flood-control measures during flood events, such as flood prevention activities and evacuation, more effective, real-time flood forecasting infomation, which reflects co ntinuously-changing precipitation and water level, is useful. In this paper, aiming at practical use of real-time flood forecasting information, a prototype of ʻthe real-time inundation flow analysis system’ is developed. In this system, radar rainfall forecasting data are automatically obtained, inundation flow analyses are performed, and the results of those analyses are automatically displayed. An example of applying this system to risk management assistance is also given.
