These features can be unlocked by Purchasing a License. Spatially resolved, coupled hydrodynamic-ecological model intended for simulation and prediction of water quality in lakes, reservoirs, estuaries and the coast. HydroNumerics develops, uses, sells and supports the 3-Dimensional coupled Hydrodynamic-Aquatic Ecosystem Model, AEM3D for simulating all water resources, including lakes, reservoirs, estuaries and coastal oceans.
Processed that are modelled include: Each license provides you with one year worth of updates and allows you to install the software on an unlimited number of machines for one user.
You can login or register Here Windows users may need to download the Intel redistributable libraries found Here to run the OpenMP version. AEM3D houses a series of mathematical algorithms that represent biogeochemical processes that govern water quality including primary and secondary production, nutrient and metal cycling, oxygen dynamics and sediment interactions.
Software ARMS included is used for visualisation. AEM3D has the capability to simulate a large number of biological species that may be present in the water body. Report a bug Atlassian News Atlassian.
Many kinetic transformations e. The configuration of AEM3D is flexible so that the user can select to model the processes that are of interest or within the limitations set by the availability of data and parameters.

Settling and resuspension; Sediment Oxygen demand; Sediment fluxes of both inorganic and inorganic components; Decomposition of particulate organic matter to dissolved; Mineralisation of organic to inorganic; Nitrification, denitrification; and Biological uptake. Quality control on code is exercised by the owner of the code see www. Time step is one hour, input data either daily or hourly for dynamic variables. Two weeks simulation time; One passive tracer; No ice model; No restarting; No dynamic bathymetry and No dynamic boundary condition files.
Time step from seconds to hours depends of domain size and grid sizes. Occasionally for periods of years. Initial data required to resolve vertical variations in lake concentration. The module will solve for pH and other solution properties, and optional mineral or gas phases can be included. HydroHubLite allows users to:. Comprehensive knowledge of lake hydrodynamics also extremely useful. Assistance is also provided through the HN Software Forums.
