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.

Empirical relationships for debris-flow deposited volumes: a case study in taiwan
Author : J. C. Chen , S. D. Chang , J. S. Wang
In this paper, several hydrogeological parameters, including rainfall intensity, characteristics of watershed area, and deposited sediment, of debris-flow events from 1985 to 2001 occurred in Taiwan are collected. An empirical relationship, which related to the rainfall intensity, runoff coefficient and watershed area, for estimated peak discharge of debris-flow isdeveloped. According to the collected data, the peak discharge of debris-flow is evaluated based on the proposed relationship, and the relation between the peak discharge and the debris-flow deposited volume as well as the relationship of debris-flow deposited volume and watershed area in the view of probability are presented through statistical analysis. The empirical relationships proposed in this paper are also compared with those obtained from previous researches.
