Sesam is a software suite for structural and hydrodynamic analysis of ships and offshore structures. [1] It is based on the displacement formulation of the Finite Element Method . The first version of Sesam was developed at NTH, now Norges Teknisk-Naturvitenskapelige Universitet ( NTNU Trondheim ), in the mid-1960s. [ 2 ]
MIKE 11 has been used in hundreds of application around the world. Its main application areas are flood analysis and alleviation design, real-time flood forecasting, dam break analysis, optimisation of reservoir and canal gate/structure operations, ecological and water quality assessments in rivers and wetlands, sediment transport and river morphology studies, salinity intrusion in rivers and ...
Although a flexible hydrodynamic modelling tool, ANUGA has a number of limitations that any potential user needs to be aware of. They are: The mathematical model is the 2D shallow water wave equation. As such it cannot resolve vertical convection and consequently not breaking waves or 3D turbulence (e.g. vorticity).
SPH is used to model hydrodynamic flows, including possible effects of gravity. Incorporating other astrophysical processes which may be important, such as radiative transfer and magnetic fields is an active area of research in the astronomical community, and has had some limited success. [25] [26]
The linear-reservoir model (or Nash model) is widely used for rainfall-runoff analysis. The model uses a cascade of linear reservoirs along with a constant first-order storage coefficient, K, to predict the outflow from each reservoir (which is then used as the input to the next in the series).
It supports river hydraulic and storm drain models, lumped parameter, regression, 2D hydrologic modeling of watersheds, and can be used to model both water quantity and water quality. As of January 2017 [update] , supported models include HEC-1 , HEC-RAS , HEC-HMS , TR-20 , TR-55 , NFF , Rational , MODRAT , HSPF , CE-QUAL-W2 , GSSHA , SMPDBK ...
In fluid dynamics, hydrodynamic stability is the field which analyses the stability and the onset of instability of fluid flows. The study of hydrodynamic stability aims to find out if a given flow is stable or unstable, and if so, how these instabilities will cause the development of turbulence . [ 1 ]
It provides analysis and real-time forecast guidance (1–16 days) on marine meteorological, oceanographic, and cryospheric parameters over the global oceans and coastal areas of the US. Products include: Ocean Waves; Sea ice; Marine Meteorology. Marine Winds - Satellite Remote Sensing; Coastal Ocean Visibility; Open Ocean Visibility; Vessel Icing
