IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

Numerical simulation of hydraulic jump by 1-d implicit upwind model
Author : Won Kim, Hongkoo Yeo , Jisung Kim
Hydraulic jump is at many cases such as dam spillway, weirs in river, however, it is difficult to simulate hydraulic jump numerically because of the discontinuous flow. Hydraulic jump includes sub-critical, critical, super-critical, and sub-critical flow at the same region consecutively, so there are some limits to analyze hydraulic jump by numerical model. This paper deals with numerical simulation of hydraulic jump. New numerical model is proposed for the hydraulic jump, verified to weir flow, and applied to dam flow. This model can simulate hydraulic jump without any internal boundary, and any additional treatment. Verification of application of new numerical model shows very good agreement between numerical results and experimental data. Therefore, this new model proposed in this paper will be effectively used for the hydraulic jump.
