【摘要】 在洪水模拟中,由于资料的不完整性,所以通常要对原始的数据进行预处理,但以前常用的线性插值等方法已不能满足计算对资料光滑度的要求,本文提出以阿克玛(Akima)光滑插值对长系列资料进行处理的方法,并在城螺河段的洪水模拟中进行了检验,模拟结果表明该方法具有较高的精度,并克服了以往处理方法所引起的资料不连续、计算耗时等缺点。更多还原

【Abstract】 In flood simulation, we usually deal with the original data in advance because of the in continuity of them. But the linear interpolation method used in the past cannot be satisfied to the demand. The paper puts forward the AKIMA smooth interpolation method for deal with the long series data, this method is verified in flood simulation of Chengluo river. The result shows that this method has a high precision and overcomes the shortcoming in old method.更多还原
