Geologically controlled sandy beaches: their geomorphology, morphodynamics and classification [PDF]

open access: yes, 2020
Beaches that are geologically controlled by rock and coral formations are the rule, not the exception. This paper reviews current understanding of geologically controlled beaches, bringing together a range of terminologies (including embayed beaches ...

The Impact of Inherited Morphology on Sandbar Migration During Mild Wave Seasons

open access: yesGeophysical Research Letters, 2023
Sandbars are ubiquitous morphologic features found in the nearshore environment throughout the world, yet predictive capabilities of their evolution remain limited.

The DynaDeep observatory – a unique approach to study high-energy subterranean estuaries

open access: yesFrontiers in Marine Science, 2023
Subterranean estuaries are connective zones between inland aquifers and the open sea where terrestrial freshwater and circulating seawater mix and undergo major biogeochemical changes.

A review on morphodynamic processes and mechanism of braided rivers

open access: yesShui kexue jinzhan, 2021
Braided river as a primary alluvial river pattern is of great importance on fluvial geomorphology, aquatic habitat, river exploitation and ecological protection. According to the literature review on braided rivers, the basic definition and morphological

Morphodynamics of phyllotaxis

open access: yesThe International Journal of Developmental Biology, 2006
A morphodynamic model for phyllotaxis based upon an axiomatic approach is presented. We show that the helical forms of alternate phyllotaxis can be derived from the assumption of the rudiment's growth and movement on the cylindrical embryo surface in the absence of a longitudinal displacement.

Observation of Rapid Seabed Erosion Near Closure Depth During a Storm Period at Hujeong Beach, South Korea

open access: yesGeophysical Research Letters, 2019
We report extraordinary seabed erosion that occurred at a depth of ~8.3 m at Hujeong Beach, South Korea. The seabed was eroded for 0.7 m during a ~2.3‐day period under storm conditions. The maximum significant wave height was ~3.8 m, which was unexpected

Quasi-two-layer morphodynamic model for bedload-dominated problems: bed slope-induced morphological diffusion [PDF]

open access: yesRoyal Society Open Science, 2018
We derive a two-layer depth-averaged model of sediment transport and morphological evolution for application to bedload-dominated problems. The near-bed transport region is represented by the lower (bedload) layer which has an arbitrarily constant ...
