  11. Water Losses Factors • Land use changes • Increasing of residence and industrial areas • Decreasing of forest and agricultural areas • Increasing of Runoff Coefficient

  12. 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

  13. 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)

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

  15. 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);

  16. 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.

  20. 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.
