Abstract: The acceleration of urbanization and global warming are making urban rain-flood disaster more ordinary and more serious recently. Summing up the characters of urban rain-floods, the mechanism of urban rain-flood disasters is analyzed. More ever, the main countermeasures to prevent urban rain-flood disasters are stated. Finally, the optimal method to utilize urban rain-flood comprehensively is put forward with the aid of artificial neural network.

Abstract: Analyzed the variation reasons and its influence factors of the Lower Yellow River (LYR), the characteristics of typical water environment abnormal variation caused by human activities and the natural influence factors are put forward. The concept of environmental abnormal variation has been proposed. Further more, the reparation methods for the environment abnormal variation in the Lower Yellow River are stated.

Abstract: Analyzed the variation reasons and its influence factors of the Lower Yellow River (LYR), the characteristics of typical water environment abnormal variation caused by human activities and the natural influence factors are put forward. The concept of environmental abnormal variation has been proposed in analyzing the processes of environmental change, and the types of water environment abnormal variation have been defined according to the characteristics of different reaches and human activities. Further more, the reparation methods for the environment abnormal variation in the Lower Yellow River are stated.

Abstract: Urban rain-flood disasters become more ordinary and serious recently under global warming and unreasonable exploitation. Summed up the characters of urban rain-floods, the mechanism of urban rain-flood disasters is analyzed. More ever, the main countermeasures to control and utilize urban rain-flood comprehensively and effectively are put forward.
