Morphodynamics of Ebb-Tidal Deltas
… to learn more about the significant drivers of ebb-tidal delta morphology using observational methods and fundamental physical relationships between forcing conditions and morphological response. Two techniques were adapted in a novel way to study the dynamics of geomorphic features at an …

Long and Short-Term Morphologic Evolution and Stratigraphic Architecture of a Transgressive Tidal Inlet, Little Pass Timbalier, Louisiana
… barrier island shorelines can be attributed to tidal inlet processes, and therefore an understanding of these processes is important to effectively manage barrier systems. High rates of relative sea-level rise within the Mississippi River delta plain have resulted in rapid landwardmigration of …

Sand transport in Chioggia Inlet, Venice Lagoon and resulting morphodynamic evolution
… to be sand. In addition, the presence of an ebb-tidal delta, extending from the mouth of Chioggia Inlet, as well as two subaqueous spits, were identified. The ebb-tidal delta annual growth was estimated as 50,000 m3/a, suggesting the existence of an additional source of sand for the delta, in …

Spatial and temporal scales of the morphodynamic evolution within the Studland complex.
… over the last 500 years. The linkage between the ebb tidal delta and shoreline progradation has been reviewed. In addition,the temporal variability of the beach system between 2001 and 2004 has been examined. These objectives have been combined to produce a nested hierarchy of spatial and temporal …

Hydrodynamic and sediment transport numerical modelling and applications at Tairua Estuary, New Zealand
… Observations and numerical modelling showed the tidal wave was distorted as it propagated into the Tairua Estuary, becoming increasingly asymmetrical with distance from the entrance. The tidal wave underwent more distortion during spring tides than during neap tides, resulting in the influx of …

Sand transport in northern Venice Lagoon through the tidal inlet of Lido
… around Lido Inlet, the largest of<br/>three tidal inlets in Venice Lagoon, Italy. Morphological analysis has established the presence<br/>of an ebb-tidal delta extending from the mouth of Lido Inlet as well as other features typical<br/>of tidal inlets. The stability of the inlet, as well as …

Dredge spoil dispersion from an inner shelf dump-mound
… medium sands from Tauranga Harbour and its ebb tidal delta. Sorting and skewness parameters and pumice content indicate that a lag surface has formed over the dump-site. Natural sediments in the onshore vicinity of the dumpsites have been altered by the deposition of fine sand and pumice …

Sediment Transport and Morphodynamics at an Estuary Mouth: a Study using Coupled Remote Sensing and Numerical Modelling
… inlet system. The sandbars that form the ebb tidal delta are highly dynamic, leading to a cyclic morphological behaviour. Application of the numerical model (MIKE21 HD, NSW, ST) served two separate functions. The hydrodynamic model has been used for the image processing and, combined with …

From Representative Period Selection to Process‐Based Sediment Dynamics
… Frisian Wadden Sea (NFWS) is a mixed-energy tidal system of interconnected tidal flats, channels, ebb-tidal deltas and barrier islands, in which tides, waves and wind jointly govern sediment transport. Despite its ecological and morphological significance, the region remains comparatively …
