Then, the distribution parameters of the probability model are amended using the small sample of the measured highest flood water level of last 10 years.
再利用后10年的实测最高洪水位的小样本，对模型的分布参数进行了修正。
South Africa raised the flood-warning level for its central Orange River area today as water levels in places were expected to reach the highest since 1996.
南非提高了洪水警报级别，奥兰治河水位已经达到了自1996年已来的最高位。
When applied to flood routing for the river reach in large water years the curve obviously improves the simulated flood processes especially the result of the highest water stage.
应用到大洪水年份河段洪水演进中，显著地提高了洪水过程特别是最高洪水位的拟合精度。
