intro story Lake


Lakes and reservoirs are important resources for communities around the globe. They provide food, drinking and irrigation water and can also offer spots for recreation. Under certain conditions lakes can also represent a threat for local communities, such as flooding or limnic eruptions. The ecological state of shallow lakes may be hampered by suspended sediments due to wind driven currents and waves. In deep lakes, stratification can cause undesirable anoxic conditions in the deeper areas. Understanding these systems is crucial to enable a sound management of these water bodies.

Delft3D is the state-of-the-art modelling framework for hydrodynamics, water quality, ecology, waves and morphology.
Here, in this space, we share knowledge & experiences, and discuss issues related to modelling of lakes.

compilation and linking problems....

compilation and linking problems....

I am attempting to install delft3d open from a tagged version which I understand is stable. I am using VS2012 and Intel 2017. In the downloaded files was a Python file which I understand prepares the solution files for the compiler. That ran OK, however, when I ran the solution files through the compiler it generated over 700 errors, 900 warnings and 55 remarks. Most appear to be of the form "Error 1025 error LNK2001: unresolved external symbol @__security_check_cookie@4 nefis.lib(gp.obj)" so I checked the FAQs and noted that the correct IFORT has to be referenced in the vcproj files. However, this is indeed correct in the files, but clearly these libraries are not being found. The warnings appear to relate to mismatched argument lists....but...first if anyone can help with the first 700 errors that would be excellent! The entire process took over 10 hours which seems a rather long time required to build a modelling system....
