Discussion of “Efficient Algorithm for Computing Einstein Integrals” by Junke Guo and Pierre Y. Julien.

The article presents discussions on articles related to hydraulic engineering. According to the author, the calculation scheme for Einstein Integrals has been proposed on the foundation of the work of one author. The new suggested algorithm can be applied in morphodynamic models. On the other hand, calculation for roughness factor for laminar flows by the use of the method stated in the equation has not been effective on the simulated results.
