Abstract: Based on the landform before flood period in 1998, to accept quasi-two dimensional sediment concentration mathematical model has carried out the forecasting calculation of flood routing between Huayuankou and Sunkou in the lower Yellow River with “1982's type” flood. It can be seen in contrast with measured data of 1982's flood that under the condition of landform at present, the flood stage is heightening in varying degrees, the reducing effect of peak flow increases obviously, the flood duration with7000m3/s above and flood propagation time increase to some extent. These have brought huge pressure and difficulties to flood control in the lower Yellow River. Therefore the situation of flood control in the lower Yellow River is still serious, the relative units should pay high attention to it.
