One of the important component in flood disaster risk reduction is the
availability of spatial information on flood risk that include: flood discharge
(q), flood depth (h), flood extent (A), flood duration (t), and the lost value
due to flood which could be quantified in the form of damage costs (Q). Change
in the value of risk f(h, A, t, Q) was hypothesized to be sensitive to climate
change and other environmental factors that exist at a river basin area.
Therefore, it is quite important to control the flood disaster risk as a part
of adaptation program to the climate change impacts and to deal with the
increasing pressure due to anthropogenic activities. Additionally, to support
the action plan and to increase the understanding and awareness related to the
flood disaster mitigation, spatial information on flood risk which having high
resolution and precision is required.
This study aimed to quantify the spatial
information of flood risk with high spatial resolution. 2-D flood-modelling
system (e.g., rainfall-runoff-inundation), climate change projection and risk
assessment have been used as the main method. Furthermore, this study has been
focused in Batanghari River basin, Sumatera and 13 river cacthments flowing
through Jakarta Capital City, Indonesia. Obtained risk information forms the
basis for long term management decisions on improving operational flood risk
management, especially in order to cope with impacts of the future climate
change.
