Albert Dai, Auteur ; Marcelo H. Garcia, Auteur |A dense inflow from a river into a lake or reservoir initiates gravity currents through a plunging process with intense mixing. The classic two-control-volume theory for the analysis of plunging phenomena has been recently corrected. In particul[...]

Albert Dai, Auteur ; Marcelo H. Garcia, Auteur |In this study we develop a theoretical model for the buoyancy-driven flow in a two-story compartment. In particular, the influence of the vent area (A*/H2) and the upper story height (beta) on the evolution of the “first front” is presented. We [...]

Robert R. Holmes, Auteur ; Marcelo H. Garcia, Auteur |An experimental field study of flows over bedforms was conducted on the Missouri River near St. Charles, Missouri. Detailed velocity data were collected under two different flow conditions along bedforms in this sand-bed river. The large river-s[...]

Francisco Pedocchi, Auteur ; Marcelo H. Garcia, Auteur |Observations of turbulent, oscillatory boundary-layer flows show that the behavior of the friction coefficient in the transition from hydraulically rough to smooth regimes is not well captured by existing semi-empirical expressions obtained for [...]

José F. Rodriguez, Auteur ; Marcelo H. Garcia, Auteur |Laboratory experiments have been carried out in order to study secondary circulation and flow variability in straight open channel flows over a rough bed. 3D flow velocities and turbulence characteristics were measured using a micro Acoustic Dop[...]

Albert Dai, Auteur ; Marcelo H. Garcia, Auteur |The meandering instability of a two-dimensional vertical plume is considered in this paper. The base flow profile is derived using boundary layer approximation and similarity hypothesis, in the spirit of Blasius boundary layer solution. Using li[...]

Fabian A. Bombardelli, Auteur ; Mariano I. Cantero, Auteur ; Marcelo H. Garcia, Auteur |Issues associated with the adequate representation of flow instabilities of saline, discontinuous density currents in two and three dimensions are discussed. First, simulations of the experiments by Alahyari and Longmire (1996) developed with an[...]

Octavio E. Sequeiros, Auteur ; Mariano I. Cantero, Auteur ; Marcelo H. Garcia, Auteur |Management of fine sediments presents an important engineering and environmental problem. The active dredging of large volumes of sediments from harbors and reservoirs involves the use of expensive equipments with large operational costs. In sev[...]

Albert Dai, Auteur ; Marcelo H. Garcia, Auteur |The stability of a pair of line vortices is considered. The two line vortices are different in strength of circulation and can be counter- or corotating. This work is a generalization reported by Crow in 1970 and Jimenez in 1975. We find that th[...]
