Abstract
Abstract. Flooding has been the most severe hazard in China from time immemorial, due
to its special geographical, climatic and socio-economic conditions. In
recent years, against the background of global climate change and rapid
urbanization, extreme hydro-meteorological events have obviously increased
in China, in turn affecting the sustainable social and economic development.
This paper analyses how modern flood risk management has evolved from the
early “build and protect” flood control approach to a broader flood risk
management approach by analyzing what has happened in China and the role of
major floods in this evolution. The development of flood forecasting models
and systems in terms of how they have informed decision-making as flood risk
management has evolved over the years. The challenging of recognizing and
dealing with forecast uncertainty and flood risk in decision-making is also
analyzed in the paper.
