简介：水库的存储能力逐渐地由于在能力(ASC)弄弯的区域存储引起变化的沉积累积被减少。建立这些曲线并且预言他们的未来变化是为水坝的规划者，设计者和操作员的一个重要问题。许多实验、半实验的途径为为这些曲线建立并且预言未来变化被建议了。在这研究，四个实验、半实验的方法被评估，他们中的三个被修改由于沉积在ASC曲线被用于变化的预言，基于为在USA的11座水库的存在沉积调查数据。为评估，这些途径被考察并且过去常决定沉积深度并且建立ASC为Mosul水坝水库(MDR)弯，它是在北伊拉克的河底格里斯河上的最大的水力的结构。MDR开始与11.11的一个存储能力在1986操作?km3和水出现区域380?在正常操作舞台的km2(330?ma.s.l)。从这些方法获得的结果用在25年水坝的操作以后在2011被收集了的观察深测术的调查数据被评估。评估结果证明三个方法为关于1.06-3.30%与百分比错误在水坝地点估计水深度或沉积深度介绍了更精确的结果。虽然为建立ASC弯，一个方法与调查数据介绍了好协议结果。而且，在为时期的MDR的水坝地点的ASC和沉积深度50，75，100和125年用修改途径和区域减小方法被估计。当与区域减小相比方法由开垦的美国局求婚了，协议及时随增加变得更好时，修改方法的结果提供了合理同意时期。

简介：在二维的空间R2的bivariate插值在一维的空间R是比那更复杂的，因为没有在R2的连续功能的Haar空间。因此，bivariate插值没为一套任意的不同pairwise点有一个唯一的答案。在这个工作，我们建议取决于点的基础的一种类型以便bivariate插值为不同pairwise点的任何集合有唯一的答案。在这种情况中，bivariate插值的矩阵把半继承因式分解。
