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.

Coupling a distributed hydrological model with a hydraulic model forflood inundation simulations

ABSTRACT
In this study, a distributed biosphere hydrological model (WEB-DHM) has been coupled with a 1D hydraulic model
(HEC-RAS) to simulate flood inundations in river basins. The newly coupled system is then applied to the upper
Citarum River Basin, Indonesia for checking its performance in reproducing flood events (particularly the inundated
area). Results show that the new system is capable of calculating flood parameters (e.g., peak flow rate, and flood
inundation area) very well in continuous simulations. The peak flow rates are well reproduced with a relative error of
-1.85% for the calibration period (1986) and 3.5% for the validation period (2005); while the simulated inundation
areas agree fairly well with the observed ones, having coincided area around 70% in both calibration and validation
periods.
