Abstract: From 2012-2013, the ice-run situation features of Yellow River Ningmeng section are:the flowing ice, the early frozen river, the low water-level of frozen river, the large water-storage of groove, the early open-up-river, the small flood peak of open-up-river and so on.The low temperature of earlier stage of frozen-river, the high temperature of earlier stage of open-up-river, the long-period flood scour of Ningmeng section of 2012 flood season are the main factors of the above features.The riverway form, the hydrologic condition, the reservoir regulation are also the important factors to influence this year’s ice-run situation.It is suggestion that the cascade reservoir united dispatch should be used to do proper water and sediment regulation to Yellow River Ningmeng section in ample-waterd year flood season and reduce pressure of the ice-run.
