Review of Experimental Studies on Rainfall-Induced Landslide Using the Laboratory Flume Technique

Abstract

Rainfall-induced landslides are one of the most influential disasters in the monsoon season for rainfall-rich parts of India, primarily southern and northeastern. Landslides are geotechnical phenomena that can be studied by conducting field experiments, laboratory experiments, and numerical modeling. Various methods can be adopted to study landslides, and the landslide flume seems to be one of the most widely used techniques for laboratory simulation of the landslides. The scaled models created in a flume can represent the real-world situations so far, which will be reviewed here. The essential aspects of this review include the practicality of the flume experiments from the previous findings, how they can be related to the real-world scenarios, the difference between field instrumentations and laboratory instrumentations, discrepancies that can occur due to the scaled effect of laboratory simulation, and recommended techniques for the future development of laboratory simulated landslides with tilting type flume incorporated with a rainfall simulator. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.
