description | event The flood on December 26, 2007, in Bengawan Solo, the Province of Jawa
Tengah has caused loss and submerged housed of thousands of people. The growing issue
in regard to the event indicated that the cause was the changing response of the cathment
area to the rain due to the land use changing. The changing of the hydrograph shape and
the amount of peak discharge can be interpreted as the form of land use changing
consequences. Thus, it is required to have a hydrological analysis to identify the changing
of the peak discharge due to land use changing.
catchment areas as the critical
In this study, hydrological analysis was carried out for Dengkeng and Jlantah
catchment areas. The hydrological analysis method used
was calculating the measured unit hydrograph (observed) by using the Collins method in
the conversion process of rain into flow, calculating the effective rain by using the Soil
Conservation Service-Curve Number (SCS-CN) and calculating the planned flood with
repetition periods of 2, 5, 10, 25, and 50 years by using the frequency analysis method.
The planned flood calculation was carried out for various land use conditions.
catchment areas from 2003 to 2009 has not
Results of this study showed that the CN value as the determinant variable of the
land function in Dengkeng and Jlantah
indicated significant improvement changes. Therefore, it is required to rehabilitate forest
and critical land as well as to optimally improve the development of the catchment areas
in the future by making efforts of land use control. Based on the plans by BPDAS Solo,
the results indicated that such rehabilitation influenced the changing of CN value and the
losses factor as well as to the effective rain in rain-flow diversity. This was indicated by
the declining flood peak discharge in 2025 from 18% to 66%. |
