Flood inundation simulation in a river basin using a physically based distributed hydrologic model

Abstract

Abstract:A physically based distributed hydrologic model is developed in this study for¯ood inundation simulation combining newly developed overland and channel network¯ow simulation models with evapotranspiration, unsaturated zone and saturated zone models. The overland¯ow and river¯ow models are validated individually with test data, and then coupled with other models. The model can take ®ne resolution spatial data as input preserving spatial heterogeneity of physical characteristics of a river basin. River embankments play an important role in¯ood prevention. The model can incorporate river embankment data in¯ood inundation simulation. The model is applied in a river catchment in Japan to simulate a¯ood event in 1996. Outputs from the model show good agreements with observed¯ood hydrographs and surveyed¯ood inundation.

Flood Damage Function Model for Residential area in Kuantan: A Preliminary Study

“…From Table 8 it's found that the damage incurred associated with content damage (RM1,100-RM11,000) is higher than the structural damage (RM500-RM6000) for LPH, as well as for MPH category. The finding is in agreement with Dutta et al [8] where in their study, the residential content damage is higher by more than 50% compared to the structural damage. In addition, the LPH experienced damage more than the MPH.…”

“…5, corresponding to flood depth and flood duration respectively. This result is supported by Dutta et al [8] and Pistrika et al [37] who found that the content damage was higher than the structural damage in their study to develop a flood damage function curve in Japan and Greece respectively. The structural damage data given by the respondents were based on the cost of repair and replacement value.…”
