Disentangling spring–neap suspended particulate matter (SPM) dynamics in estuaries
Published 2025-01-01“…</p> <p>We demonstrate the use of this framework on two model cases implemented in the idealised width-averaged iFlow model: an idealised test case where the sediment dynamics do not affect the water motion and a case representative of the Loire estuary, with strong feedback between sediment and the water motion through sediment-induced damping of turbulence. The first is illustrative as it allows a full understanding in terms of cause and effect between water motion, transport, and SPM concentration. …”
