Abstract:

Flood hazard is one of the most harmful disasters in the world for over 40% of the natural hazard damages are caused by flood hazard every year. Focusing on the problem of forecasting flood, the goal of this study is to investigate Flood Index (FI) during flood events. Such a flood index based on effective precipitation is utilized to estimate flood index from floods over Ramsar from October 15 to November 15 in 1976 and October 1 to October 30 in 1993. Daily precipitation on Ramsar station from January 1975 to December 2002 is examined to calculate indices and to compare with result. FI is calculated by considering precipitation and produces the Available Water Resources Index (AWRI) by precipitation. Comparisons of validation results from FI and AWR with observed flood over events are purposes. This study reveals FI to be promising tool for warning flood.
