How to Reduce Flood Impacts

Devastating floods sometimes occur. Humans had to combat against flood impacts in all their history, and we must also tackle such floods of the present and future eras. Indeed, the flood risk is generally increasing for the ongoing global warming. Warmer air may hold higher amount of water vapor, and some recent highly devastating flood events show direct relations to record breaking precipitation amounts for the changing climate. In this respect the outlooks to the rest of this century are unfavorable, since the atmospheric greenhouse gas concentration still grows fast, and observed air temperatures show substantial warming trend worldwide [1].
