Quantifying suspended sediment using multi-frequency echosounder measurements: Assessing the potential of single instrument sediment concentration inversions that account for variations in particle size

Echosounders are used to monitor suspended sediment concentrations (SSC) in coastal management studies and to monitor dredge plumes. Due to the dependency on sediment properties like particle size, shape and density, performance of single frequency measurements is limited when sediment properties are changing.<br/><br/>Using multi-frequency...

Quality control and clock error correction of passive seismic data from ocean bottom seismometers in the Red Sea

Three-component seismometers deployed on the sea bed have been used for many years. These so-called ocean bottom seismometers (OBS) are used to register both compressional and shear waves. The recorded seismic information is used to enhance our understanding of areas of interest located offshore, like hydrocarbon reservoirs, mid oceanic ridges,...

Calibration of optical backscatter sensor for measurements of sediment transport through the Marsdiep inlet

In highly dynamic and vulnerable tidal systems such as the Wadden Sea, the importance of understanding natural processes and how they are hampered by anthropogenic pressure is highly demanding. Within these processes the sediment transport is one of the most challenging movements to be monitored. With this in mind, suspended particulate matter ...

Progradation and erosion of a fine-grained tidally dominated delta: A case study of the Jiangsu coast, China

A large proportion of the world population lives in the coastal zone, which is facing a variety of natural and anthropogenic impacts on its evolution. A better understanding of coastal evolution can be obtained when it is based on an accurate knowledge of coastal dynamics. This thesis aims to study the long-term (hundreds of years) coastal...
