Tidal Inlet Morphodynamics

How do tidal inlets evolve, and how can we manage them better?

Morphodynamic evolution of tidal inlets and estuaries (specifically ebb-tidal deltas); hydrodynamic processes at tidal inlets and in estuaries; spatial and temporal variations in grain size.

Sediment Pathways on Ebb-Tidal Deltas

After 5 years of blood, sweat, and tears, I present to you my PhD thesis: Sediment Pathways on Ebb-Tidal Deltas: New Tools and Techniques for Analysis! I will defend my PhD on March 8th. How do sand and mud move around on our coasts?  This is a question that we need to answer in order…

Predicting the Unpredictable

Ebb-tidal deltas are notoriously unpredictable. Battered about by waves and tides, their ever-shifting sands can be a royal pain in the arse for everyone from coastal residents to pirates. I have spent most of the past five years trying to identify the pathways that sand takes across these deltas as part of my PhD. However,…

Casa en la Playa

This morning as I was finishing my first coffee, one of my Deltares colleagues shared a video of a house on the beach in El Salvador. It was a surreal, post-apocalyptic, Planet of the Apes scene, made all the more mysterious by the accompanying news text (translated from Dutch): “Abandoned villa washes up entirely on…
