Simulation of tailings release in dam break scenarios using physical models

Break fill-dam simulation using GeoStudio (case study: Safarood earth dam, Kerman)

One of the main reason of earth-dam breaks is inner erosion which is caused by washing fine soil particles and finally lead to seepage inside the dam. Seepage will decrease effective tension in the earth-dam's core and arching phenomena is occurred. More settlement of core than to shell is the consequence of arching and occurrence of cracking. In this paper, GeoStudio software based on finite e...

Floods from tailings dam failures.

This paper compiles the available information on historic tailings dam failures with the purpose to establish simple correlations between tailings ponds geometric parameters (e.g., dam height, tailings volume) and the hydraulic characteristics of floods resulting from released tailings. Following the collapse of a mining waste dam, only a part of tailings and polluted water stored at the dam is...

A Dam Break Analysis Using HEC-RAS

This paper firstly described the dam break in the aspects of theories and models. Break parameters prediction, the understanding of dam break mechanics, peak outflow prediction were shown as the essential for the dam break analysis, and eventually determined the loss of the damages. Secondly, as an application example, Foster Joseph Sayers Dam break was further modeled and analyzed using USACE ...

Diversion of Water from a Tailings Dam

Human Life Saving by Simulation of Dam Break Using Flow-3d (a Case Study: Upper Gotvand Dam)

Dam break analysis plays a very important role in the risk assessment of dams. Large dams pose significantly higher risks to the people and property downstream of the dam as compared to smaller dams. So the flooding risk due to the possible failure of large dams is more crucial. The simulation of exceptional events characterized by high hydraulic and hydro-geologic risk is an actual problem for...
