Sediment diffusion method improves wastewater nitrogen removal in the receiving lake sediments

Hi! A new publication is available where we study nitrate reduction through spatial optimization of wastewater discharge. COHERENS was used here on a 10m grid along with laboratory analysis and field experiments. Sanni L. Aalto, Jatta Saarenheimo, Janne Ropponen, Janne Juntunen, Antti J. Rissanen, M...

Re: Coherens Installation From Clean Ubuntu 16.04 LTS

I just installed COHERENS V2.11 on Ubuntu 16.04.3 LTS and didn't have any major problems compiling. I used the netCDF version available from the Ubuntu repository: sudo apt install netcdf-bin libnetcdf-dev libnetcdff-dev And in my coherensflags.cmp I have: FCIFLAGS_NETCDF = -I/usr/include FLIBS_NETC...

CIF files with COHERENS V2.11

Has something changed in the later versions of COHERENS regarding the use of CIF files? I tried e.g. the plume test case with cifruns file and the run won't work because the CIF files are not written. I also tried writing a CIF file in other codes and having the line "myrun,W," in defruns ...

Re: Possible bugs in interpolation and nesting

Thank you Patrick! I totally understand your busy schedule. I'm very much looking forward to testing if the new code release will work for us. It has been difficult to try to fix these issues ourselves, as one fix seems to lead to another problem (or maybe we have tried to fix the wrong place), so w...

Possible bugs in interpolation and nesting

Hi, I'm having difficulties including gridded weather data in COHERENS V2.9 (and in V2.10.3). Both the model grid and the weather grid are uniform rectangular (nhtype=1), but different sizes. The weather grid has more coarse resolution. The problem is that weather data doesn't interpolate correctly ...

Re: How does the model calculate the time?

Hi Sou! Have you checked that the time_zone model parameter is set correctly? From the manual: time_zone : Time zone, i.e. the difference of the local time with respect to GMT [hours]. Difference is positive (negative) eastwards (westwards) from Greenwich (0). The parameter time_zone is of type REAL...

Janne from the Finnish Environment Institute

Hi everyone! My name is Janne and I work as a researcher at the Finnish Environment Institute (SYKE). I'm responsible for developing and maintaining our 3-D basin modelling capabilities. At SYKE we're using COHERENS for our modelling needs ranging from small inland freshwater ponds to the brackish B...
