简介：在Changjiang河口的北方经过隧道的背淤泥力量的时间、空间的变化是调查u-sing实验直角的函数(文件结束)方法，与目的到决定强加的进程和时间规模。自从2000年3月，在隧道的每个挖出的单位的back-siltingquantity上的数据被收集了，主要一次15d。背淤泥力量的文件结束分析揭示二个重要模式，它完全解释58。第一个文件结束模式显示出的33%全面变化，和相应过程和time-scales.The是的一个清楚的年度周期由河流的水和输沙量决定了从在上游。第二个文件结束模式揭示在back-siltingstrength和工程活动之间的一种靠近的关系。因为这些过程极大地在这个学习案例中被互连，为41的另外的文件结束模式财务。67%全部的变化不显示出清楚的过程andtime规模。
