Abstract

In this paper, the effects of different widths and lengths of collar around bridge abutment on local scour depth are studied numerically and experimentally. Numerical simulation of scour hole evolution at bridge abutment is more convenient than the experimental modeling, because the [...]

Abstract

The development of more and more potent computers and the recent research in the field of hidroinformatics makes possible the free surface flow modelling in two dimensions caused by earthen dam failures. In this paper, the results obtained by uni-dimensional model (HEC-RAS) and two-dimensional [...]

Abstract

In 2006, a work plan was conceived tor the development of a mud transport model tor the Scheldt estuary in the framework of LTV (Long Term Vision) (Winterwerp and De Kok. 2006). The purpose of this model is to support managers of the Scheldt estuary with the solution of a number of [...]

Abstract

This work presents a coupling between two numerical models, one for mesh generation and the other for heat transfer analysis, used to characterize the tree trunk thermal behaviour located in a forest fire environment. The geometry of the tree trunk is developed, using adaptive mesh [...]
