Numerical Modeling of suspended sediment propagation in small torrents
This paper describes the Solfec computational code used to simulate multi-body systems with constraints. The Solfec code implements an instance of the Contact Dynamics (CD) method by Moreau and Jean, therefore the constraints are handled implicitly. One of the main goals of the software is to provide a user-friendly platform for testing formulations and solution methods for the (dynamical) frictional contact problem. It also serves as a development platform for other aspects of time-stepping methods (e.g., contact detection, time integration). The code applies several kinematic models (e.g., rigid, pseudo-rigid, finite element), contact detection algorithms, time integrators and constraint solvers (e.g., penalty, Gauss-Seidel). This paper also describes a method used to develop a computer code written in the Python programming language that is needed to produce a numerical model of suspended sediment propagation. The resulting computer code was applied to data from the Salt Creek stream in the Dubračina River basin. The paper also provides graphical representations of the Mud Flow simulation in the hypothetical example inside of the Salt Creek stream erosional base. Finally, some basic input parameters necessary for an efficient creation and execution of the numerical model are characterized and described in more detail.
