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.

Compiling Delft3d on OS X Yosemite successful but...

Hi all,

I followed this post and managed to successfully compile Delft3d on my OS X Yosemite (10.10.5) using necessary libraries I installed from MacPorts.

But when I test run the examples I have some runtime errors associated with date and time.

For example, when I run an example in example/01_standard (after modifying the paths in, I got the following:

Deltares, FLOW2D3D Version, Nov 14 2017, 23:11:10 entry Flow2D3D::Run

Part I - Initialisation Time Dep. Data module...
runid : f34
At line 92 of file vermdf.f90
Fortran runtime error: Bad value during integer read

The run generated 2 files before terminating,
td-diag.f34 and

The date and time in td-diag.f34 was bad (has unprintable ^@ characters, see below).

*** Deltares, FLOW2D3D Version, Nov 14 2017, 23:11:10
*** built from :
*** runid : f34
*** date,time : 2017-1^@-^@1,^@^@^@:21:07

I suspect this has to do with some differences in c/c++ time structures between Linux and OS X.
This is not surprising when I look again in the config.log file. In OS X, the -lrt library is not available and hence produced an error in the configuration stage.

Here's a snippet from my config.log.
configure:25486: checking for clock_gettime in -lrt
configure:25519: gcc-mp-7 -o conftest -O2 -I/opt/local/include -L/opt/local/li
ld: library not found for -lrt
collect2: error: ld returned 1 exit status

Can someone point me to some suspected parts of the code where this can be fixed?

Thanks very much for your attention and help.
