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.

B-jump in abruptly expanding channel

ABSTRACT
For a B-jump in abruptly expanding channels, both symmetric and asymmetric flows are observed. The hydraulic
condition required to form a symmetric flow is necessary for design purposes. In this study, the flow conditions of the Bjump
are classified into symmetric flow, periodically deflected flow, and asymmetric flow, according to the change of the
tailwater level. An expression is presented for the formation of each flow condition, determining the hydraulic condition
for the formation of symmetric flow. The relation of the sequent depths of the jump is derived from the momentum
equation. Additionally, the expression for the length of the jump is determined by considering the physical meaning of
the jump length.
