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.

Error running examples

Padawan Posts: 25 Join Date: 3/25/12 Recent Posts
Hi all,

I compiled Delft3D tag 5740 on Ubuntu 14.04 LTS using gfortran.
Everything seem OK but when I run the examples I always get the following error:

At line 831 of file prterr.f90 (unit = 33, file = 'tri-diag.f34')
Fortran runtime error: Sequential READ or WRITE not allowed after EOF marker, possibly use REWIND or BACKSPACE


However, this errors seems not to affect the result of the simulations.


Besides, when I run specifically example 10 I get:

At line 136 of file rdpart.f90 (unit = 902, file = '')
Fortran runtime error: File already opened in another unit

Delwaq2 did not run correctly.


Thank you very much for any help.
Best regards,
Francesco

I am running into the exact same error when trying example 10. Does anyone have a good idea of how to fix this? I cannot run example 10 successfully (and am having issues with another Del-waq test case I've been trying).

Thank you,
