Plant traits determining biogeomorphic landscape dynamics: A study on clonal expansion strategies driving cliff formation at marsh edges

Despite the well-recognized importance of plant traits for biogeomorphic development of landscapes, our understanding remains limited of how species-specific plant traits respond to and serve as drivers for the sedimentary dynamics within a biogeomorphic landscape. By manipulating a series of laboratory experiments, using mesocosms and a...

Salt marsh establishment in poorly consolidated muddy systems: effects of surface drainage, elevation, and plant age

Conservation and restoration of salt marsh ecosystems are becoming increasingly important because of the many ecosystem services they provide. However, the processes controlling salt marsh establishment and persistence, especially on bare tidal flats in muddy areas, remain unclear. As muddy sediments typically experience a restriction of soil...

Challenges in modelling river flow and ice regime on the Ningxia–Inner Mongolia reach of the Yellow River, China

During winter the Yellow River in China is frequently subjected to ice flood disasters. Possible dike breaking due to ice floods poses a serious threat to the part of the region located along the river, in particular the Ning–Meng reach (including Ningxia Hui and the Inner Mongolia autonomous regions). Due to its special geographical location...

On the Formation of Radial Tidal Current off the Central Jiangsu Coast

In the South Yellow Sea off the Jiangsu coast, there exists a special type of sand bodies, which are known as radial sand ridge field (RSRF). One of the characteristics of this area is the distinctive radial tidal current field. Although many studies have focused on the hydrodynamic environment around radial sand ridges, the knowledge on the...

Further Research on the Tidal Wave System in the Southern Yellow Sea

A two-dimensional tidal wave model for the Chinese marginal seas with high resolution is set up and the verification results demonstrate that it can well simulate the large domain. Based on this model, a series of numerical experiments are constructed to analyze the influence of local bathymetry and reclamation of the Jiangsu coast on the tidal...

The tidal wave system in the Chinese marginal seas

A 2D large-scale tidal wave model is set up for the Chinese marginal seas and it is proved to simulate the tidal motion in this large domain well. Based on the model, sensitivity analyses have been carried out to investigate the influences of various factors on the tidal wave system. According to the results, the effect of river discharges and...

The influence of hydrodynamic forcing on sediment transport pathways and shoreline evolution in a coral reef environment

The genesis of the radial tidal current off the Central Jiangsu Coast

One of the characteristics of the radial sand ridge field (RSRF) in the South Yellow Sea off the Jiangsu coast is the distinctive radial tidal current field. Although many studies have focused on the hydrodynamic environment around radial sand ridges, the knowledge on the genesis of the radial tidal current is still in a very basic stage. This...

Toward nonlinear modeling of meander evolution

Nonlinear simulation of meander evolution

Evolution of meanders, a complex morpho-dynamic process, has been the focus of research challenging river engineers for decades. The study replicates the natural evolution of meandering processes by coupling the Bank Erosion and Retreat Model (BERM, by Chen and Duan) with a nonlinear flow model (by Blanckaert and de Vriend). Distinguished from...

Tidal flat evolution at the central Jiangsu coast, China

A schematized process-based model of tidal flat evolution was constructed with dimensions similar to the tidal flats near the Wanggang Mouth at the central coast of Jiangsu, China. The simulated flow patterns agree qualitatively with field observations from literature, i.e. involving tidal asymmetry, current directions and tidal wave features....

Technical note for sediment transport rate: Analysis of delta flume data and calculations

Data analysis of Delta flume observations and calculationsThe objective of the present study is to analyse the measurement data of profiles and velocity moments, to derive the measured cross-shore sediment transport rates from the profile records and to compare the observed transport rates with the results from several existing prediction models...
