Dam Break Wave with Energy Dissipation : Two Case Studies
Abstract: Flood waves resulting from dam break and spillway gate malfunction may have dramatic impacts. Two related cases are the overtopping of a dam by flood waves and a sudden water release down a stepped cascade. In each instance, some energy dissipation takes place and classical dam break theory are inappropriate. Both cases were investigated in large-size facilities and in a prototype. Ne...
متن کامل1D and 2D Numerical Modeling for Solving Dam-Break Flow Problems Using Finite Volume Method
The purpose of this study is to model the flow movement in an idealized dam-break configuration. One-dimensional and two-dimensional motion of a shallow flow over a rigid inclined bed is considered. The resulting shallow water equations are solved by finite volumes using the Roe and HLL schemes. At first, the one-dimensional model is considered in the development process. With conservative fini...
متن کاملDam Break Wave of Thixotropic Fluid
Thixotropy is the characteristic of a fluid to form a gelled structure over time when it is not subjected to shearing, and to liquefy when agitated. Thixotropic fluids are commonly used in the construction industry e.g., liquid concrete and drilling fluids , and related applications include some forms of mud flows and debris flows. This paper describes a basic study of dam break wave with thixo...
متن کاملA 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 ...
متن کاملA Mathematical Model for Forecasting the Dam-Break Flood Routing Process of a Landslide Dam
Once a landslide dam bursts, its reservoir discharges quickly in a flood which will cause catastrophic damage to life and property downstream. For a specific landslide dam, the peak flow rate and the evolution of downstream flood are influenced by the shape and size of the dike breach when dam-break occurs. According to the general nature of landslide dams and field observations of dike-breach ...
