Floods in Hubei Province are generally caused by multi-factors of the global and the Yangtze-River-basin scales.The former represents the global climate anomaly,while the latter includes the physical disadvantages and the unreasonable exploitation in the Yangtze River basin.The present tactics against floods include ecological and also engineering measures,which have some significant role in preventing disasters from floods.By analyzing the cause of floods and the methods to cope with floods,a quantitative index is proposed to measure the extent of floods with total population and total proper...
