Pressure dependence of the water density in Delft3D-Flow - Coast/Estuary - Delft3D
intro story Coast / Estuary
Coast / EstuaryCoastal 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.

Pressure dependence of the water density in Delft3D-Flow

Dear all,
I have applied Delft3D to a deep lake (300 m) and faced problem with winter mixing.
In the downloadable version of Delft3D-Flow, the water density is calculated by using the one-atmosphere equation of state of seawater (Millero and Poisson, 1981).
Please could you let me know if another version with the full equation of state is available, in order to take into account the pressure dependence of the water density ? Or if a user has already programmed it ?
It should improve my simulations.
Cheers,
Frédéric
