Water Losses Factors

• Land use changes
• Increasing of residence and industrial areas
• Decreasing of forest and agricultural areas
• Increasing of Runoff Coefficient

13
Flood in 2002 inundated 85 locations with covered
16041 ha ( 17 of total area). Water logging
ranged 0.2 m to 3.0 m depth in 2 hour to 10 days
length

INTEGRATED WATERSHED MANAGEMENT

• Prevent floods (water losses) and increase
  infiltration through integrated watershed
  management
• Establish Jakarta Megapolitan water management
  system
• Transfer of water from adjacent rivers (Citarum
  and Cisadane)

Transfer water from West Tarum canal
approximately 16.0 cms or 504.6 million cmy

Integrated Watershed Management Activities

• Integrated and proper land use planning
• Implementation of conservation farming
• systems (strip cropping,
• Multiple crops farming systems including fish
  and/or livestock)
• Implementation of appropriate conservation
  techniques (mulching, terracing, contour
  planting, ridge and furrow planting)

17

• Practicing appropriate soil management techniques
  (minimum or no tillage, contour tillage, contour
  planting)
• Spring development
• Building of grass waterways, diversion ditch,
  drainage ditch
• Efficient irrigation systems and
• Building of check dams/water retardance
  structures or situ (s) in appropriate site.

CONCLUSION

• Potential water resources is 3.151 billion cmy.
• Total water demand is 2.852 billion cmy.
• Total retained water in the watershed is 1.296
  billion cmy.
• Jakarta is facing serious floods and lost of
  water during rainy season about 1.317 billion
  cmy.
• Jakarta has been deficit of water particularly
  during dry seasons.
• Jakarta Megapolitan need an integrated and
  holistic watershed management programs and
  transfer of water from neighbor watersheds.
