Abstract
Urban floods have large impacts particularly in terms of economic and social losses. Flood risk is commonly thought of as being a combination of the probability and the consequences of flooding. To analyse flooding requires a basic understanding of the hydrology of cities. The paper provides an overview of the consequences of urbanisation on the hydrology of towns and cities, try to describe the urban hydrological cycle and the processes within the cycle that result in flooding. We would like to introduce the process of urban flood risk management. The central concept of this paper is to represent how we can manage collectively the different aspects of the urban flood risk, and to demonstrate the successful management with them.
