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.

Restoration of the elasticity of ci¨¦nagas in the canal del dique system in colombia
The Canal del Dique system is located in the North of Colombia. Large scale reconstruction works in the past have
resulted in a gradual enlargement of the flow capacity of the canal, leading to major environmental and social problems.
The project ¡°Environmental Restoration of the Canal del Dique System¡± aims at improving the environmental and social
conditions in the system. One of the components for restoration are the ci¨¦nagas, a cascade of fresh water lakes that
originally formed the water system before construction of the Canal. After construction, the hydraulic conditions changed
considerably, which resulted in environmental deterioration of the ci¨¦nagas. With the help of hydraulic and topographic
data analysis, aerial photographs and the 1D2D hydrodynamic model of the Canal del Dique it was possible to derive the
elasticity of the ci¨¦nagas, as a measure for the environmental quality of the ci¨¦nagas. Most ecological indicators are
determined by the hydraulic behavior of the ci¨¦nagas as a result of the interaction between Canal and ci¨¦nagas. Although
the hydraulic system has largely changed in time due to large scale reconstruction works in the Canal del Dique system,
the ecosystem has constantly been able to adjust to the new conditions.
