  1. WATER RESOURCE MANAGEMENT OF PAKISTAN IJAZ -UL-HASSAN KASHIF SMALL DAMS ORGANIZATION ISLAMABAD

  2. INDUS RIVER BASIN FROM SPACE

  3. WATER RESOURCE MANAGEMENT • Water Resources Management is the integrating concept for a number of water sub-sectors • hydropower • water supply and sanitation • irrigation and drainage • environment. • An integrated water resources perspective ensures that social, economic, environmental and technical dimensions are taken into account in the management and development of water resources.

  4. OVERVIEW Pakistan is one of the world’s most arid countries, with an average rainfall of under 240 mm a year. The population and the economy are heavily dependent on an annual influx into the Indus river system (including the Indus, Jhelum, Chenab Ravi, Beas and Sutlej rivers) of about 180 billion cubic meters of water, that emanates from the neighboring countries and is mostly derived from snow-melt in the Himalayas

  5. OVERVIEW-2 The balance between population and available water already makes Pakistan one of the most water stressed countries of the world with rapid population growth it will soon enter a condition of absolute water scarcity

  6. DECLINING PER CAPITA AVAILABILITY OF WATER IN PAKISTAN (Cubic Meters Per Capita Per Year)

  7. WATER RESOURCES OF PAKISTAN • Rain fall • Glacier • Ground water

  8. RAINFALL • Pakistan lies in an arid and semi arid climate zone • Sources of rainfall • Monsoon • Western disturbances • Mean Annual rainfall • Lower Indus Plain < 100 mm • Upper Indus Plain > 750 mm • Average seasonal rainfall • Kharif = 212 mm • Rabi = 53 mm

  9. 10 YEARS AVERAGE(1990-99) RAINFALL OF SOME MAJOR CITIES

  10. GLACIER • Catchment area of Indus basin contains some of the largest glacier in the world outside the polar region. • Glacier area of upper Indus catchment is abut 2250 Km2 and accounts about 80% of summer runoff in river. • Kabul River originates from southern Hindukush and starts rising approximately a month earlier than Indus and fulfill the irrigation requirement of late Rabi and early Kharif crops. • Snow melt account for more than 50% of the flow in Jhelum River.

  11. SURFACE WATER ACCOUNT MAF

  12. DETAIL OF SURFACE WATER AVAILABILITY MAF

  13. SURFACE WATER SUPPLIES AND CONSUMPTIONS

  14. Ground Water Total Groundwater Potential = 55 MAF Groundwater Abstraction = 41.5 MAF Punjab(81 % abstraction) 80 % Fresh water, 20 % Saline Sind(12 % abstraction) 23 % Fresh water & 77 % Saline NWFP (5 % Abstraction) Balochistan (1.2 % Abstraction)

  15. GROWTH IN USE OF TUBEWELLS

  16. GROWING ROLE OF GROUNWATER IRRIGATION

  17. DEVELOPMENT OF IRRIGATION SYSTEM IN PAKISTAN

  18. INDUS WATER TREATY 1960

  19. INDUS WATERS TREATY, 1960 SALIENT FEATURES All waters of eastern rivers namely Ravi, Beas and Sutlej allocated to India. All waters of western rivers namely Indus, Jhelum and Chenab allocated to Pakistan except some specified uses in occupied Kashmir. Pakistan to meet the requirements of its eastern river canals from the western rivers by constructing suitable replacement works. Safeguards incorporated in the treaty to ensure unrestricted flow of waters in the western rivers.

  20. INDUS WATERS TREATY, 1960 SALIENT FEATURES Either party constructing a work affecting the other party to inform the other party at least six months in advance and supply necessary details to enable the other party to satisfy itself that the proposed work does not adversely affect the other party. Permanent Indus commission constituted to watch implementation of the treaty and resolve by negotiations any problem arising thereof. Procedure for settlement of differences and disputes outlined. Differences and disputes first to be resolved by negotiations by the permanent Indus commission failing which procedure for settling such

  21.

  23. KEY WATER INFORMATION

  24. ANNUAL CANAL DIVERSION AND ESCAPAGES TO THE SEA

  25. STORAGE PER CAPITA IN DIFFERENT SEMI ARID COUNTRIES

  26. INDUS RIVER BASIN

  27. INDUS BASIN IRRIGATION SYSTEM

  28. LARGE DAM IN PAKISTAN

  29. SALIENT FEATURE OF MANGLA DAM

  30. RAISING OF MANGLA DAM The capacity of Mangla Dam has been reduced by 19.22 % due to silting Raising of Mangla Dam is in progress, main features are: - Increase in height = 40 feet Additional storage = 3.1 MAF Additional power = 1000 GWh

  31. SALIENT FEATURE OF TARBELA DAM

  32. STORAGE LOSS IN EXISTING RESERVOIRS

  33. WATER ACCORD 1991

  34. SALIENT FEATURES OF ACCORD 1991 Existing uses of provinces remain untouched and protected. N.W.F.P / Baluchistan projects which are under execution are provided their authorized quota of water as existing uses. Need for additional storages on the Indus and other rivers admitted and recognized for planned future agricultural development. Need for minimum escapages to sea below Kotri to check sea intrusion recognized. Further studies desired to establish minimal escapage needs below Kotri.

  35. SALIENT FEATURES OF ACCORD 1991 • No restrictions on Baluchistan to develop water resources of Indus tributaries flowing through its area. • Need for establishing Indus river authority for implementation of the accord recognized and accepted. • IRSA to have headquarters at Lahore and to have representation from the four provinces. • Sharing procedure laid down in Para 14(b) of the accord • Provinces are free to under take new projects within their agreed shares. • Within their allocations provinces may modify uses both system wise and period wise.

  36. APPORTIONMENT OF WATERS OF THE INDUS RIVER SYSTEM BETWEEN THE PROVINCES-ACCORD 1991 (MAF) * INCLUDING ALREADY SANCTIONED URBAN AND INDUSTRIAL USES FOR METROPOLITAN KARACHI. ** UNGAUGED CIVIL CANALS ABOVE THE RIM STATIONS. BALANCE RIVER SUPPLIES (INCLUDING FLOOD SUPPLIES AND FUTURE STORAGES) SHALL BE DISTRIBUTED AS BELOW: PUNJAB SINDH N.W.F.P. BALUCHISTAN TOTAL: 37% 37% 14% 12% 100%

  37. SHARING PROCEDURE PARA (14) OF ACCORD. 14(a) The System Wise Allocations will be worked out separately on ten daily basis and will be attached with this agreement as part and parcel of it. 14(b) The record of actual Average System uses for the period 1977-82 would form the guide line for developing a future regulation pattern. These ten daily uses would be adjusted pro-rata to correspond to indicated seasonal allocations of the different canal systems and would form the basis for sharing shortages and surpluses on all Pakistan basis.

  38. APPORTIONMENT OF THE INDUS WATERS (PROMISE AND PROSPECTS) – AN HISTORIC ACCORD: 21 MARCH 1991 MAIN FEATURES Existing uses of all provinces to be protected. Allocations to different canal systems to be worked out separately on the basis of ten daily uses. These uses to help determine sharing of shortages and surpluses

  39. WATER APPORTIONMENT ACCORD 1991 SHARING PROCEDURE Sindh holds that the available river supply should be shared between Punjab and Sindh on the basis of para (2) accord allocations reflected in para 14(a) of the accord. Punjab emphasizes that the relevant clause for sharing of available river supply is para 14 (b) of the accord, which envisages sharing of shortages and surpluses on all Pakistan basis on the basis of average system uses 1978-82.

  40. SHARE OF THE PROVINCES AS PER WATER ACCORD 1991

  41. INDUS RIVER SYSTEM AUTHORITY • Comprises Five Members. One from each Province and one from Federal Government. • First Chairman Member Balochistan followed by NWFP, Punjab, Sindh and Federal. • Term of Office • Chairman One Year • Member Three Years

  42. DECISION MAKING PROCESS IN IRSA Decisions taken by majority votes. In case of equality of votes, chairman exercises casting vote. Aggrieved party to approach Council of Common Interest for redressal.

  43. WATER MANAGEMENT PROCEDURE

  44. PRESENT PROJECTS

  45. PAKISTAN WATER STRATEGY AND WAPDA’S VISION 2025 • The Pakistan Water Strategy and WAPDA’s Vision 2025 have reviewed likely future demands and the implied requirements for storage. • If no new storage is built, canal • diversions will remain stagnant at about 104 MAF and the shortfall will increase by about 12% over the next decade. • The Pakistan Water Strategy calculates that Pakistan needs to raise storage capacity by 18 MAF (6 MAF for replacement of storage lost to siltation and 12 MAF of new storage) by 2025 in order to meet the projected requirements of 134 MAF.
