Model description
Model type: | Modular model for the terrestrial, coastal and marine domain. |
Description: | wave-current interaction, (non) hydrostatic flow (2D/3D), salinity, temperature, (non) cohesive sediment transport, morphology, bed stratigraphy, water quality, ecology, structures & control, particle tracking, curvilinear multi-domain mesh in cartesian or spheric coord., online visualization, GUI. |
Technical information
Supported platforms: | Linux, Windows |
Programming language: | Fortran77, Fortran90, C, C++ |
Model development started at: | 1988 and development still takes place. |
To what degree will the model become available: | As executable and conditionally as code |
Current license type: | Commercial |
Memory requirements: | 20MB-2GB |
Typical run time: | hours-days |
Input / Output description
Input parameters: | Area schematization (mesh, bathymetry/topography, characteristics of structures, open boundary locations), process selection, initial conditions, forcings (boundary,atmospheric), time step, time frame, numerical settings, output options |
Input format: | ASCII |
Output parameters: | Time series of 2D/3D map data and selected point data, particle tracks |
Output format: | Binary |
Post-processing software (if needed): | No, but there is a tool available for conversion to netCDF. |
Visualization software (if needed): | Not needed since there is a GUI included. Plugins available for ESRI (GIS) and Matlab |
Process description
Processes represented by model: | drying/flooding, turbulence and large eddies, stratification, internal waves, density effects of salinity, temperature and sediment, free surface flow, wave-current interaction, wind forcing, precipitation and evaporation, sediment sorting, fluid mud, morphological change, biochemical reactions, algae modelling, nutrient cycling, atmosphere-water exchange, adsorption and desorption of substances, deposition and re-suspension of particles and adsorbed substances, bacterial , predation |
Key physical parameters & equations: | water level, velocity, temperature, salinity, density, pressure, turbulent energy, wave heights & forces, roller & breaker energy, sediment fractions, bed levels, concentrations (chloride / salinity, coliform bacteria (E. Coli, faecal and total), oxygen and BOD, temperature, organic C, N, P and Si, inorganic phosphorus, ammonium, nitrate and silica, algae (diatoms, greens, bluegreens), heavy metals, PCB-153, HCB, lindane, fluoranthene and benzo(a)pyrene) |
Length scale & resolution constraints: | length scales of modelled domains: decimeter (lab scale) to global; typical grid resolution 10 m - 10 km |
Time scale & resolution constraints: | minutes (time scales of eddies) to centuries (long-term morphology) |
Numerical limitations and issues : | relatively mild stability and accuracy constraints (depending on application) due to implicit numerical schemes |
Testing
Available calibration data sets: | generic model, no specific calibration data sets |
Available test data sets: | various public and limited access data sets used for during software development; regression testcases used for release updates; first version of formal validation document available for flow module |
