Uncertainty Analysis of Spillway Erosion Parameters

چکیده
Windows Dam Analysis Modules (WinDAM) is a set of modular software components that can be used to analyze overtopped earthen embankments and internal erosion of dams. WinDAM is being developed in stages. The initial computational modules address routing of floods through the reservoir with dam overtopping and evaluation of the potential for vegetation or riprap to delay or prevent failure of the embankment. The next module, WinDAM B, incorporates dam breach analysis; i.e., analysis of the breach failure of a homogeneous embankment through overtopping and drainage of stored water. Current work is underway to include analysis of internal erosion, nonhomogeneous, zoned embankments, and analysis of various other forms of embankment protection. The focus of this paper is on the overall software architecture, interfaces between legacy software and the existing modules, and the integration with Sandia National Laboratories’ DAKOTA software suite to conduct parameter studies and uncertainty analysis on a range of input parameters.

Internal erosion under spillway rested on an embankment dam
In this paper we investigate the mechanism of internal erosion caused in the right abutment of the Shahghasem dam’s spillway. Shahghasem dam is an earthen dam located in Yasouj, in southwest of Iran. A significant hole and pipe have been observed in the corner of the right abutment from upstream view. The foundation is Marlstone, which has low cohesion and susceptible for internal erosion and p...
متن کاملModel Investigations of Stepped Spillway
Stepped block protection has considerable potential as a low-cost method for the construction of chute spillways and the protection of embankments from erosion by overtopping flow. Stepped spillways are structurally stable, resistant to water loads and significantly increase the rate of energy dissipation on the spillway face thus eliminating or greatly reducing the need for a large energy diss...
متن کاملExperimental Study of Parallel Jets Scouring, considering the effect of jets distance on erosion rate
The scouring process at downstream of the hydraulic structures is a complex phenomenon and many parameters affecting its amount. Failure to control this phenomenon causes damages to the dam and its associated hydraulic structures. In this research, the scouring caused by the combination of jets outlet from a gated spillway was investigated experimentally and the combination of jets adjacent to ...
متن کاملDetermination of the Height and Overtopping failure of Reservoir Dams by Using Reliability Analysis (Case Study: Namrood Dam)
Generally, the design of dams and other hydraulic structures is carried out based on deterministic approaches. However, there are many uncertainties in the estimation of different effective parameters in hydraulic structures design. The inherent uncertainties in these parameters necessitate reliability analysis to ensure the structure stability. In this study, after investigating various uncert...
متن کاملSolution of Flow Field Equations and Verification of Cavitation Problem on Spillway of the dam
The main objective of this paper is to formulate a mathematical model for finding flow field and cavitation problem on dam spillways. The Navier-Stokes Equation has been applied for the computation of pressure and velocity field, free water surface profiles and other parameters. Also, for increasing accuracy of the problem, viscosity effect has been considered. Because of internal flows the eff...
