Abstract
In the recent years, the urban areas in
Taiwan are highly developed with many
buildings, which constrain the surface runoff
during floods and change the flow
conditions. The existing domestic and
foreign inundation models usually use the
ground elevations as the only input of
geographic data, without considering the
effect, of buildings in urban areas, on the
water movements. Consequently, the
simulation results of the traditional models
can not completely reflect the physical
hydraulic phenomena.
The study will integrate the spatial
information in urban areas, including the
topography, flood-proof and drainage
systems, roads and buildings, by using the
Geographic Information Systems to
establish a GIS-based inundation model for
urban areas in three years. The proposed
model takes the artificial facilities into
account for better reflecting the flood
propagation processes in urban areas.
The study will also collect the related
researches and well-developed inundation
models for model comparisons. The theory,
numerical method, applicability, limit,
functions, and operation interface of these
models would be reviewed and compared.
The comparison will provide as the
reference for the model developing of the
follow-up researches.
For practical applications, the
information techniques will be introduced to
improve the user operation and result
displaying interfaces for the developed
numerical model. The integrated software
package of the GIS-based inundation model
for urban areas will be supplied to the
professional users of water authorities for
further researches and applications, and to
international academic scholars and experts
for cooperation and experience exchanges.
