| Summary: | This study explores the origin of community perception about flood hazard and applied it into
flood hazard mapping, which is based-on community perception and action to reduce the
impact of flood hazards. The aims of this study are: 1) mapping flood hazard area based on
land physical characters and local community perceptions of flood hazards risk, 2) identifying
the coping strategy to flood hazards risk reduction, and 3) identify the suitable mitigation
action based on the community perception.

This study interviewed 147 households by questionnaire sheets in Kudus Regency, Indonesia.
This location has flood prone areas due to its topography on the flat and intermountain basin
area . Flood hazard mapping based on community
perception is produced from overlaid between flood mapping based on land physical
characters and community perception. Through scoring analysis and GIS model, the result
shows that almost 35% area of Kudus Regency is potential for flooding hazard. Most of
hazardous areas are located at the south part of Kudus Regency, which has land physical
characteristic of plain areas with 50% of clay material soil and use as rice field. These land
physical characters cause longer process of soil infiltration and consequently cause higher
surface runoff depth for longer period.

analyses reveal three coping strategies, which have been developed by local people to adapt
the negative impacts of flood: technology/structural building, social and economic. The
structural building strategy became the main influence factor due to the enormous destruction
of these floods. People constructed their first floor higher and strengthen it to reduce damages
on their properties, while the wealthy ones typically constructed second floor, or made

these flood prone areas were working together to clean their muddy environment and rebuild
the damaged. Unfortunately, this good behavior only conducted momentarily during and after
the flood hazard. Therefore, community should conduct this behavior regularly to keep their
environment and canal in clean condition. In term of economy strategy, the result shows that
some local people try to save their property such as television, electronic, furniture, and
clothes to the safety and higher place. However, both social and economic strategies do not
have significant influences among these communities.
In order to mitigate flood hazard disasters, community should ask the government to restore
Wulan, Juwana River, and canal/irrigation system frequently. The other solutions are
strengthen the Undaan embankment and construct some retention areas in the highly prone
areas or low areas, such as in Karangrowo Villages at Undaan District, Jetis Kapuan village at
Jati District, and Kirig Village at Mejobo District. Flood management should be improved, which
include improving function of Wilalung flood gate, improving the early warning system,
establishing the disaster group discussions, action, training, education and socialization about
flood disaster (emergency response, evacuate, law and regulation, etc.). In addition, there is a
need of intensive coordination between government and community as the victims of flood
hazards.
