Brienz/Brinzauls slope instability and potential landslide-dammed lake

山体滑坡阻塞河道是一个普遍的全球现象。过去河流淤塞的痕迹包括以前蓄水处的湖泊沉积物（在那里，异常大的扇形表明平静的水），河流剖面上的裂缝点，河流海盗，以前湖泊上游和大坝遗址直接下游的三角洲沉积物，大坝决口洪水沉积物，以及大坝本身的残余物（如果没有完全被侵蚀的话）。然而，高山河谷的湖泊沉积物也可能有非常不同的起源，比如冰川或构造。在瑞士阿尔卑斯山的一个活跃的、缓慢移动的滑坡中，破译湖泊沉积物的起源是这个项目的目标，因为这个地点目前显示出加速的斜坡运动。了解这个地点过去是否经历过足以阻塞河流的快速运动，将有助于我们指导未来的调查，并更好地了解这个有人居住的斜坡的动态。

Blocking of river courses by landslides is a common global phenomenon. Traces of past river blockages include lacustrine sediments in the former impoundment (where unusually large fans tell of quiescent waters), knickpoints in the river profile, river piracy, delta-sediments upstream of the former lake and directly downstream of the dam site, dam-breach flood sediments, and remnants of the dam itself (if not completely eroded) flanking a prominent breach. However, lacustrine sediments in Alpine river valleys can also have very different origins, such as glacial or tectonic. Deciphering the origin of lacustrine sediments at an active, slow-moving landslide in the Swiss Alps is the goal of this project since this site is currently showing accelerated slope movements. Knowing whether this site has experienced movements rapid enough to block the river in the past will help us guide future investigations and better understand the dynamics of this inhabited slope.
