3D Numerical Modelling of Tailings Dam Breach Run Out Flow over Complex Terrain: A Multidisciplinary Procedure

Numerical Prediction of the Wind Flow over Real Hilly Terrain

In the present paper, a numerical prediction of the wind flow in a neutrally-stratified atmosphere over real hilly terrain is presented. For the solutions of the NavierStokes equations which are the governing equations of a microscale atmospheric flow, a numerical model based on the finite-volume formulation in a boundary-fitted coordinate system and the SIMPLEC pressure-correction algorithm is...

Numerical simulation of topographic effects on wind flow fields over complex terrain

This study addresses the issues pertinent to both the topographic effects on wind flow fields over complex terrain and the accuracy of computational fluid dynamics (CFD). The numerical simulations using isotropic eddy viscosity and wall functions are conducted based on the numerical solutions of the incompressible, nonisothermal, steady-state turbulent flows, in which a regional computational m...

Diversion of Water from a Tailings Dam

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...

Recirculation over complex terrain

This study generated eddy covariance data to investigate atmospheric dynamics leeward of a small, forested hillside in upstate New York. The causes and effects of recirculation eddies were examined to support the larger goal of improving measurement of the exchange of energy, moisture, and trace gases between the terrestrial biosphere and the atmosphere over complex terrain. Sensors operated at...
