Environmental Fluid Dynamics Code (EFDC) is a multifunctional surface water modeling engine that includes hydrodynamic, sediment-contaminant, and eutrophication components designed to simulate aquatic systems in one, two, and three dimensions.

Over the years, DSI has continued developing EFDC and into what is now known as EFDC+. To learn more about different versions of EFDC, please visit A Review of EFDC Versions - EEMS Blog

After you Prepare your environment.

Execute the following:

git clone https://github.com/dsi-llc/EFDC_Plus.git
cd EFDC_Plus
chmod -x toolkit-setup.sh

Run the setup script and pass in your package manager parameter (ubuntu users would use apt).
If you want to be able to compile the code, use option -c. If you just want to be able to run efdc, use option -r.

toolkit-setup.sh <-r or -c> <package manager name> 
# example: toolkit-setup -r apt

Alternatively, you can download and follow the installation steps from intel:
Intel OneApi Base Toolkit
Intel OneApi HPC Toolkit

Load the intel environment variables.

source /opt/intel/oneapi/setvars.sh

Install NetCDF library (for Ubuntu users)
Run the command to update the package lists for upgrades for packages that need upgrading

sudo apt update

Install hdf5 and hdf5-devel libraries using the command:

sudo apt install hdf5-tools hdf5-helpers libhdf5-dev libhdf5-doc libhdf5-serial-dev

Install the libnetcdf-dev:

sudo apt install libnetcdf-dev

Install m4 package:

sudo apt-get install m4

Download netcdf-fortran-4.5.2 from the website https://github.com/Unidata/netcdf-fortran/releases/tag/v4.5.2
Go to the netcdf-fortran-4.5.2 folder and create config-intel.sh as the following:

export FC=mpiifort
export F77=mpiifort
export F90=mpiifort
./configure

Run config.sh

./config.sh

Build NetCDF-Foxtran
Go to the NetCDF-Fortran source code folder and run the following commands

make check
make install

Run the below command for checking whether NetCDF and NetCDF-Foxtran are installed propertly or not

nc-config --all

Add the DNCOUT flag to the FFLAGS section in the makefile for supporting NetCDF

make -f Makefile
chmod -x efdc.x  # this allows the built file to be executed as a program.

The run command structure is

cd /path/to/project
mpiexec -n <number of nodes> path/to/efdc.x -NT<number of omp threads>

An example of a run command for a model with 4 mpi domains, running with 6 omp threads per domain (24 cpu cores total) would look like:
mpiexec -n 4 ~/code/efdc/efdc.x -NT6
