Observations of Multiple Internal Wave Packets in a Tidal River Plume

Remotely sensed images document the occurrence of multiple packets internal solitary waves (ISWs) in Rhine River plume at same time. We use a combination field observations, and non-hydrostatic hydrostatic modeling to understand processes that lead generation retention ISW within plume. Previous numerical shows tidal front is trapped mid-field for more than one cycle due straining recirculation plume, resulting presence fronts near-and regions. In this work, we show how variations strength these can release packets. conclude region modulation explain A frontal Froude number analysis generated during previous ebb tide ISWs addition newly released front.
