黃河的河套段北部和及下游入海部分,均會比南面河段提早結冰及延遲融冰。冬季時,河套北部及河口河段首先結冰;春季時,河套南部及河口以南河段首先融冰,產生大量的融冰水和碎冰塊,但因北部河段尚未開封,導致河流水位上升;兩者均使河道阻塞溢流,形成氾濫。

黃河中上游沒有大湖泊調節河流流量及過濾沙泥,也促成了氾濫的出現。






唔該

North Yellow River's He Tao section and the downriver enters the seato be partial south side, can compare the section of river to shift toan earlier time ices up and retards melts the ice. When winter, norththe He Tao and the river mouth section of river first ices up; Whenspring, south south of the He Tao and the river mouth the section ofriver first melts the ice, produces the massive friendly ice water andthe garrulous ice piece, but because north the section of river notyet Kaifeng, causes the rivers water level rise; Two causes the rivercourse to block the overflow, forms 氾 overflows. Middle and upper reaches Yellow River not the big lake adjusts therivers current capacity and filters the slag, also has facilitated theappearance which overflows.

Yellow River's the bend of a river section north and and downstream enters sea part, can than south reach freeze and delay melt ice advance average. Winter time, the bend of a river north and estuary reach first of all freeze; Spring time, the bend of a river south and estuary to the south reach first of all melt ice, bring forth a flood of melt ice water and broken ice, but because north reach not yet Kaifeng, lead to river water level on raise; Both make riverway obstruct overflow flow average, form Fan overflow.

Yellow River in headstream has no big lake regulating river rate of flow and filtrate sand mud, cause Fan overflow appear too.

North Yellow River's He Tao section and the downstream enters the sea part south side, can compare the section of river ahead of time to ice up and the detention melts the ice.
When winter, north the He Tao and the river mouth section of river first ices up; When spring, south south of the He Tao and the river mouth the section of river first melts the ice, produces the massive friendly ice water and the garrulous ice piece, because but north the section of river not yet Kaifeng, causes the rivers water level rise; Both cause the river course blocking overflow, forms overflows。
Middle and upper reaches Yellow River does not have the big lake to adjust the rivers current capacity and the filtration slag, also has facilitated the appearance which overflows.
