Deposition and erosion of silt-rich sediment-water mixtures

From a granulometric point of view, sediment can be classified as sand, silt and clay. Silt is thereby defined as sediment with particle sizes equal to, or larger than 2 μm and smaller than 63 μm, with quartz or feldspar as base mineral. Note that quartz and feldspar particles can be smaller than 2 μm. To date, our knowledge on deposition and...

On the hindered settling of silt-water mixtures

The sedimentation behavior of silt particles in the hindered settling regime has been considered. Therefore, laboratory experiments are carried in especially designed settling columns. Silt-water mixtures are prepared and allowed to settle at various initial concentrations. During the settling process, a continuous vertical concentration profile...

Calibration Report Annular Flume: At the Faculty of Coastal Engineering, Zhejiang University

Estuarine systems worldwide contain large quantities of fine (cohesive) sediment. Fate and transport of these sediments is to a large extent governed by erosion and deposition processes. Knowledge on the behaviour of these sediments is required for modeling purposes in order to predict impacts on morphology and environment as a result of e.g....

Coastal Erosion Processes near sea dikes in Hai Hau district, Vietnam

The erosion problem in Hai Hau coastal district (Vietnam) is the subject of this thesis. The exact processes that drive this ongoing erosion however are not well defined yet, and therefore two main goals are defined. The first goal is to gain more insight into the processes that drive the ongoing erosion in Hai Hau. The second goal is to predict...

Physical model tests with movable bed in front of seadikes

Coastal erosion is a serious problem in several coastal areas in Vietnam. One of these areas is the district of Hai Hau, located in Nam Dinh province. This district suffers from severe coastal erosion, the coastline has been retreating for more than 100 years. Efforts have been made to stop this erosion which resulted in the construction of...
