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.

Physical habitat simulations using unsteady flow model
Author : BYUNGWOONG CHOI(1), SEUNG KI KIM(2) & SUNG-UK CHOI(3)
ABSTRACT
Physical habitat simulations were carried out to investigate the impact of hydropeaking on the stream morphology and habitat
suitability. A 20 km long reach located downstream of a dam in Korea was chosen for the study area. Zacco platypus was found to be
a dominant species in the study area. The 1D unsteady flow model and the habitat suitability index model were used for the hydraulic
and habitat simulations, respectively. The results from the physical habitat simulations provided the impact of flow regulation on the
stream morphology and habitat suitability. The importance of considering the sorting of the bed materials on the stream morphology
and habitat suitability was also discussed. The validity of the quasi-steady model for computing the long-term change in the stream
morphology and the short-term change in the habitat suitability is also investigated.
