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
Ideal data for testing: controlled laboratory experiment, or well documented field study with extensive measurements and/or remote sensing data

User groups

Currently or plans for collaborating with: cooperation with various US institutes and universities (ONR/NSF context), USGS, NUS Singapore, Dutch universities and institutes, ...

Documentation
