HydroAS | Description
HydroAS is a versatile and reliable software for the 2D simulation of watercourses and the surface runoff of precipitation. It is based on the numerical solution of the shallow water equations using the Finite-Volume-Method.
HydroAS provides script-driven simulations: Thus, model data can be changed, queried, output or read in during the simulation. Therefore, very complex control processes can be modeled in water management systems.
HydroAS has a wide range of applications including:
- River flooding analysis
- Heavy rainfall analysis/ urban flash flood modeling
- Sediment erosion/depositions studies in river channels and floodplains
- Tidal wave propagation
- Pollutant dispersion in a waterway
HydroAS | Features
Short calculating time for millions of elements
Calculation accuracy guaranteed by extensive lab tests and real-world applications
High stability, robustness and accuracy for a wide spectrum of hydrodynamic conditions
Volumetric accuracy of the tidal wave propagation over complicated topography
Results showing flow speed, direction, and flood depth
Current changes caused by sediment aggradation/erosion are accurately simulated due to fully coupled transport (solid matter/pollutant/heat) and hydrodynamic solver
Transport simulation transport of up to twelve grain dimensions at the same time
Easy data input and operation through coupling with Aquaveo software SMS
64-Bit Windows-Version and Linux Version available
Optional performance boost through the use of graphics cards (GPU) or multiprocessing
A graphical user interface allows you to conveniently run calculations, test procedures and export data.
Available in English and German for Windows and Linux
HydroAS MapView enables the visualization of results in interactive animations.
HydroAS | MapView
The MapView add-ons enable the creation of impressive map animations from HydroAS results, to illustrate the progression of a flood caused by heavy rain or a flood event.
MapView Converter conveniently creates the required data set for the animation from the result files. Numerous display and control functions can be defined. MapView Converter requires a separate license and supports HydroAS version 5.2 or higher.
MapView Online provides the animation of the flood progression via internet. It enables you to publish heavy rainfall hazard maps for a municipality on the internet or communicate calculation results to your client very easily.
MapView Desktop is used for the offline presentation of calculation results. It visualizes the results interactively, offering many display and control functions.The map animation can be exported to and played from a memory stick.
HydroAS MapView Desktop is available free of charge.
HydroAS | Scripting
With HydroAS you can replicate very complex control systems for water management by script-controlled simulations. Model data can be changed, queried, exported or imported during the calculation. The technical base is the widely used scripting language Lua.
HydroAS thus provides a foundation on which users can creatively develop their own applications.
- Control systems for weirs, sulices, etc.
- Automatic reading of inflow time series
- Bidirectional interaction with other models (groundwater, sewer network models)
- Simulation of dike or dam breaches
