Decadal changes in variability of salinity patterns in an estuarine network
In this subproject, we aim at quantifying the statistics of salt intrusion lengths in an estuarine network under influence of changing external forcing conditions, geometric changes and anthropogenic measures. Statistics will include the probability density distribution, from which e.g. mean, standard deviation and return periods will be computed. Salt intrusion length will be defined as the distance of the 1 psu isohalines in the network to the mouth, but also the statistics of positions of other isohalines conditions will be calculated. External forcing conditions concern hourly variations of wind, tides and incoming waves, and daily variations in freshwater discharge as well as the occurrence of events, such as storm surges. Interventions that will be considered include deepening of channels, closure or opening of branches. The challenges addressed in this subproject are:
- To explain the decadal time-scale behaviour of salinity patterns in an estuarine network, with the RM-estuary as a prototype system.
- To quantify the statistics of estuarine salt patterns resulting from variability in forcing conditions, changes in the geometry and trends in external forcing conditions.
