Gravity Currents from a dam-break in a rotating channel

Helfrich, K; Mullarney, J


The generation of a gravity current by the release of a semi-infinite region of buoyant fluid of depth H overlying a deeper, denser and quiescent lower layer in a rotating channel of width w is considered. Previous studies have focused on the characteristics of the gravity current head region and produced relations for the gravity current speed cb and width wb as a functions of the local current depth along the wall hb, reduced gravity g′, and Coriolis frequency f. Here, the dam-break problem...[Show more]
