Abstract - A simple method for the computation of dam-break waves
We describe a simplified method for computing dam-break waves and the results of the corresponding validation tests. Computation for one given cross section only uses data relative to the dam and that section completed by the Manning-Strickler coefficient for the reach between the dam and that section. The references of the various comparisons consist of computations with a model solving de Saint-Venant equations. Results are generally good as well for maximum water heights (difference less than 30% in more than 90% of sections) as for maximum velocities and wave arrival times. We also note this important point that the uniform flow equation is verified between maximum discharge and maximum water height.

What is OpenURL?

The OpenURL standard is a protocol for transmission of metadata describing the resource that you wish to access.

An OpenURL link contains article metadata and directs it to the OpenURL server of your choice. The OpenURL server can provide access to the resource and also offer complementary services (specific search engine, export of references...). The OpenURL link can be generated by different means.

  • If your librarian has set up your subscription with an OpenURL resolver, OpenURL links appear automatically on the abstract pages.
  • You can define your own OpenURL resolver with your EDPS Account.
    In this case your choice will be given priority over that of your library.
  • You can use an add-on for your browser (Firefox or I.E.) to display OpenURL links on a page (see http://www.openly.com/openurlref/). You should disable this module if you wish to use the OpenURL server that you or your library have defined.
