Numerical modelling of overflows is significantly more complicated than standard 1-dimensional
river or sewer modelling. The objective of this study is to determine to which extent the
physical models can be replaced by numerical computations. Only main points and
examples are given in this paper; a more complete description is found in Nielsen (2007). …
In order to assess the numerical model for a 3-D flow situation where the flow direction
changes in the area of critical flow, a model of a side weir was set up. Figures 5 and 6 show …
Abstract
The present study uses laboratory experiments to evaluate the reliability of two types of numerical models of sewers systems:
