| Summary: | Juwana Catchment has been suffering several major past flood events with
significant loss. Since 2010, the flood risk management is applied in this
catchment includes the plan of retention basin and dam development in Logung
Sub-Catchment in 2014. The establishment of retention basin and dam to reduce
the flood risk especially in Logung Sub-Catchment should be evaluated. This
study conducted an assessment of flood risk before and after the establishment by
using OpenLISEM as flood model to generate the flood hazard map. The
vulnerability assessment is focused on crops with four crops type: red chili,
watermelon, sugarcane and paddy. These crops are the predominant crops on the
flood prone area. Risk evaluation shows that the retention basin and dam only
reduce the total discharge for 2 years and 10 years return period but for 25 years
return period the retention basin and dam are giving very small influence to
reduce flood risk.
