摘要
应用张启舜的“河流与水库泥沙冲淤过程计算数学模型”对黄河河口三角洲及其以上河道的冲淤过程进行了验算,并在验算过程中依据实测资料,对模型的模式和程序进行了部分修正。使用该模型对1965—1987年艾山以下河道和钓口河、清水沟两流路冲淤变化实测资料进行了拟合验算,取得了较好成果。验算结果表明,现行清水沟入海流路,只要经过流路的合理安排,科学治理和适当提高设防水位,还可延长使用30～50年。
By using the 'Mathematical Model for Calculating the Procedure of Scouring and Silting in A River or Reservoir' by Zhang Qishun, the scour and sedimentation in estuarine delta and the upper course of it were calculated. In the same time, the structure of model was partly revised according to the data measured. The model revised was used to check the practical scour and sedimentation in two courses: one is from Aishan to Diaokouhe (1965—1975) and another is from Aishan to Qingshuigou (1976—1987). The results were agreed well with the data measured. Consideration from the calculating results, that the course being in operation now from Aishan to Qingshuigou could last 30—50 years further if rational arrangement, scientific regulation and properly raising the design flood level were provided.
