چکیده
The author presents an interesting method to forecast nonlinear kinematic flood waves (Serrano, 2006). As a first remark, the discussers would like to stress the fact that the proposed method is an approximate solution and not an analytical solution, as suggested by the title of the paper. Indeed, an analytical expression is given by the backwards characteristics methods, as in Eq. (6) of the paper. However, since this solution is implicit, the author proposes an approximate explicit solution by making simplifying assumptions. The discussers would like to raise two points in this discussion:

A Numerical and Analytical Solution for the Free Vibration of Laminated Composites Using Different Plate Theories
An analytical and numerical solution for the free vibration of laminated polymeric composite plates with different layups is studied in this paper. The governing equations of the laminated composite plates are derived from the classical laminated plate theory (CLPT) and the first-order shear deformation plate theory (FSDT). General layups are evaluated by the assumption of cross-ply and angle-p...
متن کاملFamily-oriented requirements engineering
Modern software products shall be developed within a short time and at the same time they should be of a high quality. Software engineering is able to fulfill these requirements by prefabricating components. Within a domain, planned and comprehensive reuse of components is supported by the concept of system family development. A system family is based on a reference architecture made of assets,...

متن کاملElectrostatic analysis of the charged surface in a solution via the finite element method: The Poisson-Boltzmann theory
Electrostatic potential as well as the local volume charge density are computed for a macromolecule by solving the Poisson-Boltzmann equation (PBE) using the finite element method (FEM). As a verification, our numerical results for a one dimensional PBE, which corresponds to an infinite-length macromolecule, are compared with the existing analytical solution and good agreement is found. As a ma...
