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 ...
This type of model would be considered a “lag convolution”, because of the predicting of the “lag time” as water moves through the watershed using this method of modeling. Time-series analysis is used to characterize temporal correlation within a data series as well as between different time series. Many hydrologic phenomena are studied ...
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] The foundations of hydrodynamic stability, both theoretical and experimental, were laid most notably by Helmholtz, Kelvin, Rayleigh and Reynolds during the nineteenth ...
The partial differential equations modeling the system's stream function and temperature are subjected to a spectral Galerkin approximation: the hydrodynamic fields are expanded in Fourier series, which are then severely truncated to a single term for the stream function and two terms for the temperature. This reduces the model equations to a ...
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).
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 ]
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 ...
