FLUXOS-OVERLAND

• Soure code for the FLUXOS-OVERLAND model. The original code (named as FLUXOS) was written in FORTRAN and consisted of the coupling of 2dmb, +QeS2, MODFLOW and MT3DMS.

• Modifications (from FLUXOS to FLUXOS-OVERLAND):

  • Converted to C++
  • Uses: Armadillo template-based C++ library for linear algebra
  • Removed: MODFLOW and MT3DMS (currently there is no baseflow)
  • WINTRA algorithm was integrated for calculation of runoff-soil interactions and nutrient release: https://onlinelibrary.wiley.com/doi/full/10.1002/hyp.11346

Branches

• master: All changes made in adesolver and adesolver_wintra have been merged into master
• developnment: branch used for development before merge with master
• adesolver: Adection-Dispersion-Reaction equation solver was converted to C++ and debugged
• adesolver_wintra: the wintra algorithm was added

Compiling

• cmake: CMakeList is provided
• Library dependencies: Armadillo
• Cmake minimum version: 3.10

Execution (and input files and folder needed)

• Create a folder with name "Results" inside the working directory where the input files and fluxos are
• input files (see examle in Working_example folder)
  • master input file: e.g., modset
  • DEM file (Esri ASCII-format raster with headers removed -> this will be fixed soon)
  • DEM of the basin (sub-set of the main DEM file for FLUXOS to know where the boundaries of the basin are)
  • Snowmelt timeseries (time,mm/day)
• to execute: ./fluxos_cpp "argument_1" (where "argument_1" is the mater input file)

Visualization of results (stored inside "Results" folder)

• visit: https://wci.llnl.gov/simulation/computer-codes/visit/

Supporting scripts (post-processing)

• "fluxos_python" folder

Working example

• "Working_example" folder
