numerical methods on shallow water modeling
 

Hi I want to work on shallow water modeling, so I am searching for references on advanced method for modeling scoure in open channel using finite volume method. thank you for your attention. M.R.Hadian phd student on hydraulic eng.,dept. of civil eng.

Dear Mr. Hadian,

Please check out TIDAL, the finite-volume CFD code specifically written for shallow water bodies such as bays, estuaries, rivers, lakes and coastal waters.

Information on TIDAL can found at:

http://www.acricfd.com/software/tidal/tidal.htm

The pricelist for TIDAL is also online.

Cheers,

Tolga Sakman

Most of the numerical methods concerning open chanel flow are presented in these three journals : Journal of Hydraulic Research, IAHR; Journal of Hydraulic Engineering, ASCE; International Journal for Numerical Methods in Fluids. There are many papers concerning the computation 2D shallow water equation by finite volume methods.

Some useful references are :

Re: numerical methods on shallow water modeling
 

I have, personally, found the account of Shallow-water model in S Al-Sanea "Numerical Modelling of Shallow-Water Flows" especially easy to read and make use of.
The number of his examples and experiments have been used to validate the performance of PHOENICS solver to simulate subcritical, turbulent and supercritical shallow-water flows as a stepping stones for the creation of ROSA package to handle the oil spill simulation in natural rivers.

Dear MR Hadian

I suggest you look at the website: numeritek.com and the library NUMERICA. This has sub-library called HYPER-WAT that consists of 13 source finite volume codes for the shallow water equations.

See also forthcoming book: "Shock-capturing methods for free-surface shallow flows" by E F Toro, Wiley and Sons 2001, to appear.

Hello,

Are there any possibilities to get the NUMERICA code from somewhere?

Anuga
 

Hell M.R. Hadian,

I have come across the open source program ANUGA in the past (named so as it was developed by the Australian National University (ANU) and Geoscience Australia (GA)):

http://sourceforge.net/projects/anuga/

and:

http://anuga.anu.edu.au/

The program solves the 2D shallow water wave equations using a finite volume implementation - originally developed for the solution of inundation and dam break problems. It is written in python, and, as such, requires a python interpreter to work.

I've got minimal experience in using it myself, but it seems to have a growing band of users.
