General Statement: There are three main aspects associated with the cause of flood   in Jakarta: global, regional, and local.

Body : Global warming partly to support for heavy rainfall events

1.   Warmer air can hold more moisture.

2.   Extreme amounts of rain/increasing frequently and intensity of heavy rainfall.

3.   Global warming changes climate conditions.

B.     Regional Aspect       : Deforestation region because of development of farms plantations and housing has reduced rain water absorption.

1.  Discouraging flood prone area.

2.  Protecting natural system such as wetland that help buffer against floods.

C.     Local Aspect             : Deforestation region because of human presence and subsequent activities near river has also contributed the problem, the city ground surfaces are primarily covered by hard material.

 

III.    Conclusion

        To conclude, to accommodate the levels of rainwater needs integrated drainage system and an increase in the size of water channels also program to dredge sediment from the city’s rivers, canals and lake.

 

 FLOOD IN JAKARTA

 

As the rainy season comes, special district of Jakarta faces serious problem such as flood, the greater Jakarta districts is prone to floods and mudslides. The very heavy rains in Jakarta have created severe flooding in many parts of the capital and its surrounding districts. There are three main aspects associated with the cause of flooding in Jakarta: Global, regional and local.

Jakarta and all coastal cities in the world face a high potential of flooding due to global warming. Global warming partly to support for heavy rainfall events. Such as Global warming changes climate conditions, Warmer air can hold more moisture then extreme amounts of rain / increasing frequently and intensity of heavy rainfall. From the regional point of view, Jakarta’s flood resulted from large amounts of water from upstream rivers in West Java that flowed across the capital. Deforestation in the headwater regions because of development of farms, plantations and housing has reduced rainwater absorption, sparking massive water flows to lower areas and, hence, flood in Jakarta. To avoid the flood, there are some plans such as discouraging flood prone area, protecting natural system such as wetland that help buffer against floods, then develop artificial lakes to act as water reservoirs along the West Java border outside Jakarta to take the brunt of the overflowing river. The West Java authority is only reluctantly providing land for this purpose. The third cause of Jakarta’s flood is the local factor. Many urban experts argue that the lack of open spaces and green areas in Jakarta is a source of the flood, The city ground surface are primarily covered by hard material, as rainwater cannot be absorbed by the ground surface. Being an urban area, the city’s ground surfaces are primarily covered by hard materials in the form of buildings, roads, parking lots and other amenities.

Unfortunately, Jakarta does not have an integrated drainage system and even lacks appropriate water channels. Old channels, built in the 1960s are maintained to this day, although they are no longer sufficient to accommodate the current levels of rainwater. The water channels should be sufficiently large to accommodate the runoff water and so avoid overflowing water that causes flood. Beside an integrated drainage system and an increase in the size of water channels, there needs to be an ongoing program to dredge sediment from the city’s rivers, canals and lakes.
