APPLICATION OF INUNDATION ANALYSIS MODEL IN NAGOYA CITY CONSIDERING SEA LEVEL RISE DUE TO GLOBAL WARMING

抄録

Nagoya city is one of the largest city located at central zone of Japan. Main rivers such as Shounai River, Shin River, Hori River, and Yada River etc. are passes through densely populated city area and terminated into Pacific Ocean. A synthetic urban inundation model is applied for the simulation of inundation in the Nagoya city in various cases such as sea level rise by 0.5m, 0.95m, 1.5m, 2.0m with the design rainfall of 10 years return period. From this study, it is found that if the sea level rises more than 1m then severe inundation occurs in the densely populated city area between the Hori River and Nakagawa canal. Furthermore, the effect of sea level rise on the sewerage system is examined.
