Flooding is one of the major natural disasters that
can cause not only disruptions to daily lives but also
damages to our properties. The study of flood models
to determine inundation areas has therefore become
increasingly more important for decision makers and
the authorities. Being readily accessible, the Artifi-
cial Neural Network (ANN) scheme was frequently
adopted for hydrology and flood modeling. Most
ANN techniques primarily take into account rainfall
data and then predict runoff consequences. Despite
convincing successes, they usually neglect other
causative factors. This study thus focuses on con-
figuring and improving generic ANN for inundation
areas identification using various flood deterministic
attributes. Accordingly, an ANN was developed using
nine flood causative factors, derived from relevant
thematic layers. They consist of flood plain in
the past, height above sea level, water density, water
blockage, sub basin areas, soil drainage capability,
land uses and monthly rainfall, whose prognostic values
were previously reported and assessed against the
full scale census and comprehensive GIS survey with
satisfying cogency. The guidelines and precautions
suggested in this paper may be applied to various
ubiquitous ANN based frameworks for flood forecasting
and related risks assessment.
