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.

Intensity-duration-quantitty (idq) analysis for probabilistic flood warning system
Author : J.G. KIM (1), B.S. KANG (2)
research is to suggest a probabilistic flood warning system procedure for river floods in small and midsized
basin. The procedure for estimating flood capacity at any duration using Intensity-Duration-Quantity (IDQ) originated
from the existing IDF, and its application example were described. Based on rainfall estimation by the IDQ analysis, it is
possible to calculate the equivalent peak hydrographs include same water level or quantity with various rainfall durations,
and IDQ curve derived under various water levels using hydrological model. This system includes uncertainty components
of hydrological model parameters and suggests probabilistic flood warning system using Monte Carlo simulation. This
study shows that the IDQ curve can estimate quickly an expected flood quantity and water stage in channels or reservoirs
using rainfall forecasting.Form Required :
