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.

Hi,

Where i can find the source code of calculate surface temperature
tsurf  = r0(nm,k0,ltem)
and temperature in layer?

Thanks.

Hi Mitia,

You are looking for heatu.f90. This code is situated in src/engines_gpl/flow2d3d/packages/kernel/src/compute/
See comments in the file for explanation of the formulas.

Regards,

Dmitry

Hi Dmitriy,

No, i can't find computation of surface temperature in heatu.f90. In this file variable tsurf eq. r0(nm,k0,ltem). So i asked where i can find computation of r0(nm,k0,ltem).

Thanks.

Hi Mitia,

In heatu.f90, heat fluxes at the surface are computed and stored in the arrays sour/sink.

In "src/engines_gpl/flow2d3d/packages/kernel/src/compute/difu.f90" (or the Van Leer variant difuvl.f90), the constituent array at the new time, r1, is computed, based on the constituent array at the previous time, r0, and the sour/sink terms.

Regards,

Adri
