简介：Marius山是月亮的靠近的一边上的一个暴烈的高原。它具有为它暴烈的特征的高集中的大兴趣，包括屋顶，锥，山脉，和rilles。然而，这个高原的词法、按年代先后的特征很好没由于早使命数据的低分辨率被学习。这研究在月亮的侦察Orbiter(LRO)(0.5m/pix)上在Selene-1(10m/pix)和狭窄的角度照相机(NAC)上用地面照相机(TC)的最近的高空间的分辨率图象描述暴烈的特征的详细形态学。我们这里报导象熔岩试管的天窗和残余那样的一些新结构。我们与ClementineUVVIS数据划分了幽灵似地同质的区域并且在每光谱的联合起来与月亮的Orbiter(LO)IV和TC图象做了坑尺寸频率分发(CSFD)大小。我们首先报导1.10的绝对模型年龄为Marius暗岩1的Ga，为Flamsteed暗岩的1.49Ga，和为Schiaparelli的1.46Ga暗岩。另外，我们识别了几个更年轻的熔岩事件：他们是Marius暗岩2(814妈)，媒介到低钛暗岩(949妈)，和无差别的中等的钛暗岩(687妈)。最后，我们为Marius山的形成建议一种披风羽毛情形，它能解决以前的模型的矛盾。

简介：在世纪的功课上，河系统重重地为水，沉积和冰的安全分泌物的目的被训练了，并且改进航行。传统地，堤是被增强并且提高了更高保护国家免受以前的伤害洪水层次。其它比技术工程答案答案打字，例如增加洪水运输能力的措施(例如，丁提和泛滥平原阴沉，阻碍堤)变得更流行。这些答案可以然而增加河床动力学并且因此否定地影响航行，维护挖出和洪水安全。许多数字模型是可得到的在河过程上预言河恢复工作的影响。经常，很少注意都没对对无常的评价被给予。在这篇论文，我们显示出我们怎么能用一条随机的途径使无常明确。这条途径帮助识别无常来源并且在河过程估计他们的贡献到全面无常。途径给工程师系统行为的更好的理解并且使他们能与河系统干涉，以便避免不希望得到的状况。我们为在荷兰在来因河优化低地河恢复工作说明这条随机的途径的优点。
