Risk Response Strategy Research of Water and Sediment Regulation System running schemes in the yellow river

Based on the sensitivity analysis on risk factors, the risk response strategies were consequently proposed, and the basic theories of the strategies were introduced in detail. The main procedure of the strategies includes listing the risks to cope with, estimating the main risk resistance capability, developing the risk consistent measures and formulating alternative risk response strategies. Some principles were followed during the strategy formulation such as appropriateness, timeliness, consensus agreement, clear responsibility and optimization. Risk response strategies can be put forward from the following several aspects with consideration: risk management program, risk control strategy, project control, labor control and management control. To select risk response strategies, the risk loss as well as the nature and composition of the cost needs to be analyzed considerately. Finally, the countermeasures for risk mitigation were suggested, namely risk transfer strategies and risk retention measures.
