Summary Contact Technical specs In/Output Process Testing Other Component info Also known as Model type Single Model part of larger framework Note on status model Date note status model Incorporated models or components: Spatial dimensions 1D, 2D, 3D Spatial extent Continental, Regional-Scale, Landscape-Scale, Watershed-Scale, Reach-Scale, Patch-Scale, Grain-Scale Model domain Coastal, Marine One-line model description Bergen Ocean Model Extended model description A three-dimensional hydrodynamic multi-purpose model for coastal and shelf seas, which can be coupled to biological, re-suspension and contaminant models. Has been used in a variety of configurations from resolving grain-scale up to seasonal scale processes. Can be run with optional MPI parallelization or run-time visualization via PGPLOT. Programmed with the goal that the same executable can be used for all cases, by using allocatable arrays and cases defined via a single configuration file pointing to input data in files typically in the same directory.

Yes If above answer is no, provide end year model development Code development status Only maintenance When did you indicate the 'code development status'? 2020 Model availability As code Source code availability (Or provide future intension) Through web repository Source web address https://org.uib.no/bom/ Source csdms web address Program license type Other Program license type other Memory requirements Typical run time Describe input parameters Wind, rivers, submerged inlets, lateral open boundaries, surface heat flux, a limited number of numerical schemes can be chosen, ... Input format ASCII, Binary Other input format Describe output parameters Currents, salinity, temperature, ... all model variables. Output format ASCII, Binary Other output format Pre-processing software needed? Yes Describe pre-processing software idealized experiments can be run with simple text files as input, but for realistic cases input data needs to be created with e.g. python, matlab or fortran scripts. Post-processing software needed? Yes Describe post-processing software model supports a variety of output to ascii or binary files that relatively easy can be read into e.g. matlab or python plotting packages. Gnuplot as also been used. Visualization software needed? Yes If above answer is yes Matlab Other visualization software Python matplotlib, Gnuplot, etc. Describe processes represented by the model Free surface flow of water. Conservation of heat, salinity, mass, turbulent kinetic energy, dissipation. Describe key physical parameters and equations Current speed, temperature, salinity, sea surface elevation, wind speed, river fluxes. Based on Navier Stokes equations, Boussinesq approximation, terrain following coordinates (sigma) Describe length scale and resolution constraints Uniform horisontal resolution, i.e. works best for resolutions < 20km. Describe time scale and resolution constraints No assimilation means it works best for simulations shorter than ~6months unless boundary conditions are carefully tuned to avoid model drift. Describe any numerical limitations and issues Free surface formulation does not support rapid changes in water elevation like hydraulic jumps in rivers. Describe available calibration data sets Upload calibration data sets if available: Describe available test data sets Upload test data sets if available: Describe ideal data for testing Do you have current or future plans for collaborating with other researchers? Is there a manual available? Yes Upload manual if available: Media:USERS GUIDE for a modesplit sigma-coordinate numerical ocean model.pdf Model website if any org.uib.no/bom Model forum / discussion board Comments This part will be filled out by CSDMS staff OpenMI compliant No but possible BMI compliant No but possible WMT component No but possible PyMT component Is this a data component Can be coupled with:
