Abstract


This research is aimed to assess the flood hazard in part of Surakarta using
hydrodynamic modelling. Flo2D software is used to simulate the flood for 10, 25
and 100 year return period. The modeling results include two flood parameters, i.e
water depth and flow velocity. A comparison was made in flood hazard mapping
between single parameter and multi parameters. The multi parameters hazard
maps improve the reliability of the hazard class delineation. The impact assessment
is done in two point of view, human safety and property damage. The further
impact assessment is done by calculating the number of buildings affected by flood.
