Abstract
In the Dutch coastal zone, where
the marine environment is characterized by shallow depths and highly energetic
hydrodynamic conditions, the cohesive sediments, or mud, play an important role
in the local morphology. For instance, mud deposits and high concentrations of
suspended particulate matter (SPM) occur frequently, especially during extreme
wave conditions, which lead to a great concern to transportation authorities
and coastal managers. Several researchers contributed to the understanding of
the cohesive sediment dynamics in the Dutch coastal zone. Nevertheless, the
mechanism of cohesive sediment transportation, deposition and resuspension,
especially due to wave effects, needs further studies and careful formulation.
The main objective of this study is
to increase the understanding of the complex patterns of cohesive sediments
transportation, deposition and resuspension due to wave effects with tide,
wind, density-driven flow in the Dutch coastal area. The study focuses on the
areas adjacent to the approach channel of the
Based on the scale linkage theory
of de Vriend and rules of Roelvink to keep models simple, the study is carried
out with three models at different spatial and temporal scale. Firstly, the
study starts with the extension of the existing ZUNO model of the
A distributed simulation solution software is
developed to utilize the distributed computation abilities in the local area
network based on the named pipe technology. And it has been proved to be
efficient during the models simulations.
