intro story Coast / Estuary

Coast / Estuary

Coastal systems are among the most dynamic physical systems on earth and are subject to a large variety of forces. The morphodynamic changes occurring to coastlines worldwide are of great interest and importance. These changes occur as a result of the erosion of sediments, its subsequent transport as bed load or suspended load, and eventual deposition. 
 
Estuaries are partly enclosed water bodies that have an open connection to the coast. Estuaries generally have one or more branching channels, intertidal mudflats and/or salt marshes. Intertidal areas are of high ecological importance and trap sediments (sands, silts, clays and organic matter).
Within the Delft3D modelling package a large variation of coastal and estuarine physical and chemical processes can be simulated. These include waves, tidal propagation, wind- or wave-induced water level setup, flow induced by salinity or temperature gradients, sand and mud transport, water quality and changing bathymetry (morphology). Delft3D can also be used operationally e.g. storm, surge and algal bloom forecasting.

How to consider sea level rise escenarios with Delft3D Flow?

Padawan Posts: 25 Join Date: 4/6/17 Recent Posts
Hi, I want to use Delft3D to simulate different escenarios of sea level rise in an estuary.

In a previous work I simulated water levels in a time series format using for the open boundary tide gauge measurements for two different periods of time of the year. Now I would like to use the same input data to simulate different sea level rise escenarios (Since I do not have tidal constituents). Is there a way to incorporate a sea level rise rate in the model?

Thank you in advance for your help.

Hi Esther,

 

I've been searching for the examples and found several references to Storm Surge Modeling of Typhoon Haiyan at the Naval Oceanographic Office Using Delft3D and Integrated Biogeomorphological Modeling Using Delft3D
 on Worldwidescience. Hope there examples could be helpful for your research too.

Hi Esther.  Can you not simply add a constant value to the timeseries values in your .bct file?

I am thinking about this problem too, or may we just add a constant value (sea level variation) to the bathymetric data, since the depth  below mean water level and is defined psoitive downward.

I think it's better to add sea-level rise to the water level for the open boundary.

It's great that coastal system could be observed by 3d models, as example literature review dissertation writing could do the same
