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.

Spillways labyrinth discharge coefficients according to position in relief channel
In recent times more dams are starting to use labyrinth weirs to replace structures due to the fact that the original structure
is insufficient. This weir increases the volume of discharge in a high event situation. The advantage is the actual increase
of the body's normal level of water to replace dam volume losses, while maintaining the same level of high water. These
losses might be due to sedimentation and incomplete hydrology. The position of the weir in the discharge channel
influences the increase of the discharge, and it is well known that the larger amount of water that is placed above this
structure, far from the effects of the channel walls, the larger the discharge coefficient becomes. The numerical
specification (graphics discharge coefficient) is important to be implemented in any design or rehabilitation. This aspect is
important in cases where spill weirs are replaced by maze cornices, which seek to maximize the available space.
