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 calibrate astronomic tide forcing components?

How to calibrate astronomic tide forcing components?

Hi everyone,

I'm modelling water level for an estuary just for a month. I am using water level with astronomic forcing as the open boundary. I just have two things, the astronomic components (amplitude, phase) for my open boundary and the observed time series data for the month I'm interested in. I'm not sure how to calibrate the armonic components, since I don't have the corrections or other data. Is there a simple way to calibrate this data? Maybe with statistic as if it were two sets of time series data?

Thanks for all the help!
