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.

Differential damage assessment due to dam failure
Author : ANGEL N. MEN®¶NDEZ (1), LEANDRO KAZIMIERSKI (2) & MART®™N SABAROTS GERBEC (3)
ABSTRACT
In the context of a dam failure risk assessment process for Yacyreta dam, on the Parana River, a numerical model study
to determine the consequences of the associated flood is described. The 1D model, based on HEC-RAS, extends 300
km downstream from the dam, and 400 km upstream Paraguay River, the main tributary of the Parana River. The model
is carefully calibrated and verified. Failure scenarios are established. The model is used to delimit the zones downstream
the dam where flood levels would be higher than the ones associated to natural floods, and the rate of rise of the water
level relative to natural floods. Issues regarding problem schematization, hypotheses verification, and information
extraction from model results are discussed. The obtained results are considered as illustrative for any very big dam in a
very big plain river basin.
