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

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
Planning
Design
Construction
Operation
Monitoring and Evaluation

11. Integrated Water Resources Management (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
Dimension 1
(water resources)
Include all forms of water occurrence (surface water, groundwater, fossil water, saltwater)
Blue water: water in rivers, lakes , shallow aquifer
Green Water : water in unsaturated zone

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