Landslide dam - Wikipedia
A landslide dam or barrier lake is the natural damming of a river by some kind of landslide, such as a debris flow, rock avalanche or volcanic eruption. [1] If the damming landslide is caused by an earthquake, it may also be called a quake lake. Some landslide dams are as high as the largest existing artificial dam. [2]
The formation and impact of landslide dams – State of the art
Apr 1, 2020 · With this review we aim at offering a unified landslide dam terminology, propose a new classification scheme based on existing ones, compile existing landslide dam inventories and thereby create a worldwide database, present the state of the art on formation and stability, and, review the impact of landslide dams over multiple timescales (see 1 ...

Most landslide dams are remarkable short-lived. In a sample of 63 documented cases, 22 percent of the landslide dams failed in less than 1 day after formation, and half failed within 10 days. Overtopping was by far the most frequent cause of landslide-dam failure.
Characteristics and classification of landslide dams associated …
Apr 4, 2017 · In this paper we aim to study a number of representative landslides of various types as well as the corresponding landslide dam features and stability. We then propose a new classification system of landslide dams according to dam composition material and sedimentological features.
Recent technological and methodological advances for the investigation ...
Jul 1, 2021 · New research on the interior structure and depositional facies of large landslides helps better understand the relationship of landslide sedimentology to dam stability, such as preferential seepage pathways or processes of overtopping failure.
Landslide Dam - SpringerLink
Jan 1, 2016 · Landslide dams are formed by landslide (see entry Landslide ) deposits or moving landslides which block a permanent or ephemeral water course leading to the formation of a natural reservoir which fills with water and/or sediments.
Recent Advances in Stability and Failure Mechanisms of Landslide …
Mar 28, 2021 · Numerous landslide dams have been induced in recent years as a result of frequent earthquakes and extreme climate hazards. Landslide dams present serious threats to lives and properties downstream due to potentially breaching floods from the impounded lakes.
PERSPECTIVE ON LANDSLIDE DAMS. - USGS Publications …
PERSPECTIVE ON LANDSLIDE DAMS. The most common types of mass movements that form landslide dams are rock and soil slumps and slides; mud, debris, and earth flows: and rock and debris avalanches. The most common initiation mechanisms for dam-forming landslides are excessive rainfall and snow melt, and earthquakes.
Recent research on landslide dams - a literature review with …
Different approaches in methodology and their relevance and application potential for engineering and mitigative measures are reviewed and several shortcomings outlined, with a view towards possible future research directions.
A global-scale applicable framework of landslide dam formation ...
Jul 12, 2024 · A framework of landslide dam formation susceptibility evaluation was designed for large-scale studies to avoid the traditional dependence on landslide volume calculations based on empirical relationships, which requires comprehensive local inventories of …
