Brienz/Brinzauls slope instability and potential landslide-dammed lake

山体滑坡阻塞河道是一种普遍的全球现象。过去河流堵塞的痕迹包括前蓄水池中的湖泊沉积物（异常大的扇体告诉人们静止的沃茨）、河流剖面中的断点、河流盗采、前湖泊上游和坝址直接下游的三角洲沉积物、溃坝洪水沉积物以及突出溃坝两侧的大坝本身残留物（如果没有完全侵蚀）。然而，阿尔卑斯河谷的湖泊沉积物也可能有非常不同的成因，如冰川或构造。该项目的目标是破译瑞士阿尔卑斯山一个活跃、缓慢移动的滑坡的湖相沉积物的起源，因为该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够快的运动来阻挡河流，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.
