Li, W. (author)
Hyperconcentrated flow/flood is a water-driven sediment transport phenomenon, which is characterized by high sediment concentrations between normal sediment-laden flow and debris/mud flow. In a hyperconcentrated flow, strong interactions exist between water flow, sediment, and river bed, which may not only change the flow rheological properties,...

The Sand Engine is a mega-nourishment constructed in 2011 with the purpose of replenishing the surrounding southern Dutch coast by exploiting the strength of local alongshore currents for the next 20 years. Long term monitoring of the Sand Engine depends upon remote sensing coupled with in-situ measurements due to both its large spatial and...

Land reclamations and island coasts often involve strongly curved shorelines, which are challenging to be properly modeled by numerical morphological models. Evaluation of the long term development of these types of coasts as well as their response to storm conditions requires proper representation of the governing physical processes. Not all...

The morphology of tidal basins includes a wide range of features developing along different spatial and temporal scales. Examples are shoals, channels, banks, dunes and ripples. Coastal engineers use their engineering tools to answer questions on the processes governing the short term (< decades) development of these morphological features....

The Rif and the Engelsmanplaat form together a supra- to intertidal flat-complex at the fringe of the ebb-tidal delta and the back barrier area in the Frisian Inlet, located between the Dutch Wadden Sea Islands Ameland and Schiermonnikoog. The complex divides the Frisian Inlet into the Pinkegat Inlet in the west and the Zoutkamperlaag Inlet in...

A process-based model for the Yangtze Estuary is constructed to study the sediment transport in the estuary. The proposed model covers the entire tidal region of the estuary, the Hangzhou Bay and a large part of the adjacent sea. The dominant processes, fluvial and tidal, are included in the model. The calibration of the model against extensive...

Thuan An is a tidal inlet located in Vietnam in a tropical monsoon area. The inlet is very dynamic and variable under the influences of not only tides and waves from the sea but also flows and floods from upstream rivers. Therefore, morphodynamic behaviour of the inlet is very complicated and not well understood. Studies on inlet are also facing...

We model branching channel patterns in short tidal basins with two methods. A theoretical stability analysis leads to a relationship between the number of channels and physical parameters of the tidal system. The analysis reveals that width and spacing of the channels should decrease as the slope of the bottom profile and the Shields parameter...

The Feiyun River, with a length of 203 km and a catchment area of 3252 km2, is one of eight rivers in Zheijiang Province (see fig.1-1), China. It flows into the East China Sea in Shangwang of Ruian City. The source of Feiyun River is at Xialing located in the border between Zheijiang and Fujian Province. The tidal influence can reach up the...

The present paper describes an analysis of the morphological integrityof the multiple channel system (MCS) of the Western Scheldt estuary. The tidal flats and surrounding ebb and flood channels form morphological cells, and the entire MCS can be schematized as a chain of such cells. The major ebb and flood channels have lost their one time...

Bed-levelling experiments are conducted in a straight laboratory channel. The experiments involve a significant fraction of suspended sediment transport. The purpose of the experiments is to provide data for modelling of the direction of sediment transport on a transverse sloping alluvial river bed, specifically in presence of suspended sediment...

A suspended sediment transport experiment in a straight flume with a mobile bed is reported. The bed topography is non-horizontal. The flow is steady. Due to an obstruction in the entrance a steady bed oscillation is generated. The bed topography is measured by means of manual bed soundings (by Delft Hydraulics). Suspended sediment...

A laboratory experiment in a 180 degree curved flume with a mobile bed and suspended sediment transport is reported. The flow is steady. The bed topography is measured by means of a profile indicator. Free and forced alternating bars are present. The steady part of the bed topography, which is forced by curvature, is characterized by a below...

Some information is given how to use the scour model DUCT-SUSTRA (Hoffmans, 1991). The scour model predicts the morphological process in scour holes or trenches and consists of two separated sub-models: a flow model DUCT and a morphological model SUSTRA. The flow model is based on the equation of continuity and the momentum equations for...

A laboratory experiment in a 180 degree curved flume with a mobile bed and suspended sediment transport is described. The flow is steady. The median sediment diameter (160 micrometer) is larger than in the preceeding experiments, run no. 1 to 3 (90 micrometer). The bed topography is measured by means of a profile indicator. The bed topography is...

It is very convenient to make use of rivers as water supply for various purposes, i.e. irrigation, industrial and domestic uses. Even if it is a very common practice, the utilization of river waters must be carefully planned and its consequences analysed. For example, before starting on a new withdrawal of water the need of water supply more...
