  1. Concepts in Water Resources Management Part (1)

  2. IWRM • Planning: is a scientific approach for decision making. • Understand; • Explore; and • Suggest. • Policy:Intention, What should be done? • Strategy: What could be done? • Program/Action plan: What will be done? • Reference framework: It sets the context, base and tools for the planning • Comprehensive integrated Planning: Integration of multi-disciplines associated with relevant stakeholders participation

  3. 27 Years Average Precipitation

  4. Human Interference on hydrologic cycle Man uses water or protects himself against water Water supply Irrigation Drainage Sanitation Flow regulation Power generation Navigation Flood protection Wastewater pollution Which of the uses are considered consumptive ?

  5. What Makes Water Special • Vital to sustain life • No substitute • High value • Public good • Finite • Consumptive uses • High demand than renewable • Private good • Fugitive • Difficult to assess • Stochastic • Common pool resources Why water is not an ordinary economic good, Hubert H.G. Savenije, 2002

  6. Important Terminologies Water Resources Development (WDP) Water Resources Planning (WRP) Water Resources Management (WRM) Integrated Water Resources Management (IWRM)

  7. Water Resources Development • WRD • Actions both physical and administrative that lead to the beneficial use of water resources for single or multiple purposes • To people in arid countries ?? • Drought relief • Irrigation • Jobs • Food security • To people in wet countries ?? • Water works • Navigation • Flood protection • Hydropower • To Palestinians ?? • Semiarid • Accessibility

  8. Water Resources Development • To water engineers • Dams, reservoirs • Flood protection • Water supply and distribution • Water treatment • To environmentalists • habitat • pollution • deforestation • wetlands • To lawyers • legislations • Water rights • International law • To economists • Economic development • Poverty alleviation • Employment generations Examples • Drilling new wells for domestic use • Upgrading and rehabilitation of water supply network • Construction of wastewater treatment plant which has multi-purpose

  9. Water Resources Planning • WRP • Planning for the development and allocation of a scarce resource (sectoral and inter-sectoral), matching water availability and demand, taking into account the full set of national objectives and constraints and the interests of stakeholders • Multi-sectoral • Domestic, industrial, agricultural, environmental, etc. • Multi-objective • Water supply, aquifer protection, flood prevention, etc. • Multi-constrained • Physical, financial, environmental, etc.

  10. Water Resources Management • WRM • The whole set of technical, institutional, managerial, legal, and operational activities required to plan, develop, operate, and manage water resources • A process including all activities of planning, design, construction, and operation of water resources systems Construction Planning Design Monitoring and Evaluation Operation

  11. Integrated Water Resources Management (IWRM) • IWRM • Water resources management that takes full account of: • All natural aspects of watershed • Interests of water users • National objectives and constraints • Institutional framework and stakeholders Include all forms of water occurrence (surface water, groundwater, fossil water, saltwater) Dimension 1 (water resources) Blue water: water in rivers, lakes , shallow aquifer Green Water : water in unsaturated zone

  12. Integrated Water Resources Management (IWRM) Household (domestic) Dimension 2 (water users ) Quantity and Quality of Water Industrial , agriculture, fishers, ecosystems, hydropower, recreation…etc. Dimension 3 ((Spatial Scale • Large Scale • International level • National level • Province and district level • Local level • Hydrological System Boundaries • River basin • Sub-catchment • Watersheds

  13. Strategic Issues • Sustainable development • Biodiversity • Green house effect • Climate change • Awareness • International water • Population growth • IWRM
