Abstract
An estuary
forms the transition between the ocean/sea
and a river and within its boundaries fresh
and salt water mix. Fresh water intake points
may be located within the reach of salt intrusion.
In order to justify political and managerial
decisions it is thus necessary to understand
and be able to predict the process of
salt intrusion in estuaries. For
one-dimensional dynamic simulation of the
hydrodynamics and salinity intrusion the
modelling suite SOBEK is available. In the Netherlands this software is used to evaluate the impact of for example measures and climate change on salinity intrusion in the Dutch Rhine Meuse Delta (RMD). Recent validations of SOBEK have mainly focused on water levels and discharges, while less attention was payed to its capability to
describe salt transport. Therefore the
objective of this research is to obtain
a better understanding of dynamic
one-dimensional modelling of salt transport
and improve the governing formulations
with the newest scientific insights
