Friction-Induced Roll Motion Short-Crested Surface Gravity Waves
2009/1/16
Induced streaming due to deep water surface gravity waves propagating at oblique angles to each other is studied theoretically on the basis of a Lagrangian description. The ocean is slightly viscous, ...
Hydraulic Control of Sill Flow with Bottom Friction
Hydraulic Control Sill Flow Bottom Friction
2009/1/13
The hydraulics of strait and sill flow with friction is examined using a reduced gravity model. It is shown that friction moves the critical (or control) point from the sill to a location downstream. ...
