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.

Modelling and application of one-dimensional river ecosysem model
Author : YOSHIHISA AKAMATSU(1) & HIROYUKI NAGANO(2)
ABSTRACT
In the river assessment, it is necessary to discuss the mass balance in the river ecosystem using river ecological model. A
new model of river ecosystem consists of one-dimensional unsteady flow, one-dimensional calculation of bed variation,
heat balance, water quality and biological model. This model was applied to Saba River, where water quality and
biological environments have been observed at four points in the river basin in two month intervals. The temporal
variations of water level, water temperature, dissolved oxygen and amount of attached algae obtained from this model
show a good agreement with the observed results, indicating that this model is valid for simulating the mass balance in the
river ecosystem.
