frey hydrodynamics provides the development and application of hydrothermodynamic simulation models on the highest scientific level. Because of its comprehensive capacity, the model MACH3 developed by frey hydrodynamics yields efficient decision assistances. MACH3 can be applied on all inland waters (ponds, lakes, rivers, estuaries) and on all oceanic waters (inland seas, shelf seas, oceans). The possible applications imply comprehensive investigations of waters dynamics and transport of matters as well as assessment and optimization of sustainable measures. MACH3 is the indispensable tool not only for the physically adequate recording of the basic hydrodynamics, but also for investigations in subjects of Environmental Protection   Ecology   Coastal Protection   Hydraulic Engineering These applications are exacting very high qualities from a numerical model. Why MACH3 fulfils these requirements, this you can look up in detail in the - scientific - description of the model MACH3
