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

Frontiers 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.

Singularly perturbed degenerated parabolic equations and application to seabed morphodynamics in tided environment [PDF]

, 2010
In this paper we build models for short-term, mean-term and long-term dynamics of dune and megariple morphodynamics. They are models that are degenerated parabolic equations which are, moreover, singularly perturbed.

A review on morphodynamic processes and mechanism of braided rivers

Shui 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

Simple assessment of spatio-temporal evolution of salt marshes ecological services [PDF]

, 2019
A number of previous research studies have addressed the enormous role played by biodiversity and ecosystems in human well-being and have placed particular emphasis on the consequences of the reduction or loss of these services. A handful of studies have

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

Royal 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 ...

A parameterization of flow separation over subaqueous dunes [PDF]

, 2007
Flow separation plays a key role in the development of dunes, and modeling the complicated flow behavior inside the flow separation zone requires much computational effort.

Cross-Shore Suspended Sediment Transport in Relation to Topographic Changes in the Intertidal Zone of a Macro-Tidal Beach (Mariakerke, Belgium)

Journal of Marine Science and Engineering, 2019
Sediment transport is a key element in intertidal beach morphodynamics, but measurements of sediment transport are often unreliable. The aim of this study is to quantify and investigate cross-shore sediment transport and the resulting topographic changes

Comparing Aggradation, Superelevation, and Avulsion Frequency of Submarine and Fluvial Channels

Frontiers in Earth Science, 2020
Constraining the avulsion dynamics of rivers and submarine channels is essential for predicting the distribution of sediment, organic matter, and pollutants in alluvial, deltaic, and submarine settings.
