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.

Estimation of Floats Flow Measurement by Means of Three Dimensional Flow Analyses around Bridge Piers
Author : Akihiro Kadota and Shoji Okada
The field measurement by tracking the floats is usually conducted to estimate flood discharge in rivers. It is assumed that the movement of floats is associated with flow velocity on water surface. The estimated surface velocity is multiplied with some correction factor so that the cross-sectional mean velocity and discharge are estimated. In order to estimate the accuracy of float flow measurement, 3D flow analyses were conducted. The observed mean velocity was compared with the result of 3D flow analysis for the accuracy of mean velocity estimation from float flow measurement.
