Tóm tắt

When a concrete dam failure occurs, negative reverse waves often appear at upstream and positive forward waves appear at downstream. This article presents several hydrodynamic characteristics of dam break wave dynamics at the reservoir upstream in case of a concrete dam breaks. Results obtained from computational research using 3D mathematical models with the RNG k-ε turbulence flow model, show that at upstream there is a pair of negative reverse waves in front and positive waves behind
