3. Introduction-River Basin Planning
 A river basin can be defined as the geographical area demarcated by the topographic
limits of the system of waters, including surface and subsurface water, flowing into a
common point.
 River basin planning is defined as the process by which decisions are made over the
competing uses and different demands for water resources and associated systems
within the basin of the river.
 River basin management is defined as the management of water resources of a basin
as a part of natural ecosystem and in relation to their socioeconomic settings.

4. Need for river basin planning and
management
 River basins are the natural entities in which freshwater appears, the ultimate source of
nearly all water used and nowadays also the receptors of most wastewater.
 From the earliest civilizations up till now, river basins have played an important role in
sustaining communities of people and other forms of life. They are used ever more
intensively and many of them are under pressure.
 Conflicts may increased of the upstream and downstream areas of the river.

5. Need for river basin planning and
management continued…
 Such conflicts may be exacerbated is international river basins, where socioeconomic
inequities among them are often much greater ,as are differences in power, and where
conflicts may lead to loss of life and a reduced capacity of governments to respond to
domestic needs.
 The slightly exaggerated term “Water wars” is appearing now and then in newspapers.
 The incidence of floods in quantity and in severity is also considered to be increasing.
Causal links with unbalanced human occupation and watershed destruction are also
likely.

6. Need for river basin planning and
management continued…
 Thus management of river basins becomes necessary as freshwater and other services
provided by basins become scarce and competition increases for their use.

9. Function of water resources planning
 To assess the current situation, formulate visions, set the goals and targets
 To provide a framework for public participation and feedback
 To increase legitimacy
 To interactions among the concerned organizations and the stakeholders

10. Introduction-Integrated Water Resources
Management
 Integrated water resources management(IWRM) has been defined by the technical
committee of the global water partnership(GWP) as “a process which promotes the
coordinated development and management of water, land and related resources, in order
to maximize the resultant economic and social welfare in an equitable manner without
compromising the sustainability of vital ecosystem.”
10

11. Why Integration Needed ?
 River basin development involves the coordinated and harmonious development of the
various works in relation to all the reasonable possibilities of the basin.
 These may include irrigation and drainage, electric power generation, navigation, flood
control, water treatment, industrial and domestic uses of water, recreation and wildlife.
 The complexity of the physical river system, the exchange of groundwater and surface
water vice versa and the continuous interactions between the environmental elements is
a physical imperative.
11

12. Why Integration Needed ?
 To prevents disputes between the states in
respect to river to meet social and natural
demands in river basins, Integrated Approaches
are indispensable.
12

13. Why Integration Needed ?
 Integration of environmental objectives, combining quality, ecological and quantity
objectives for protecting highly valuable aquatic ecosystems and ensuring a general
good status of the water resources.
 Integration of all water resources, combining fresh water and ground water bodies,
wetlands, coastal water resources at the river basin scale.
 Integration of all water uses, functions and values into a common policy framework,
investing water for the environment, water for health and human consumption, water
for economic sectors, transport, water as a social good.
13

14. Why Integration Needed ?
 Integration of disciplines, analyses and expertise, combining hydrology, hydraulics,
ecology, chemistry, soil sciences, technology engineering and economics to assess
current pressures and impacts on water resources and identify measures for achieving
the environmental objectives of the directive in the cost effective manner.
 Integration of all significant management and ecological aspects relevant to sustainable
river basin planning including those which are beyond the scope of flood protection
and prevention.
 Integration of water management from different member states for river basin shared
by several countries, existing and/or future states.

15. Conceptual view of IWRM
 Conceptual view of IWRM has been
presented by the van beek (2002) who termed
it as a “structured process of policy analysis.”
 Integration of the Natural system itself
considered as land and water.
 Storage of the water depends on the
vegetation cover and land properties.

16. Concept of IWRM continued…
 The concept of IWRM as an integrating
handle, growing from subsectoral to cross
sectional management.
 Water resources management modelling
of a river basin system should include not
only natural and physical processes but
artificial processes like hardware and
software processes include.

17. Principles of IWRM
 Social equity: It means ensuring equal access for all users (particularly
marginalised and poorer user groups)to an adequate quantify and quality
of water necessary to sustain human well being.
 Economic efficiency: It means bringing the greatest benefit to the
greatest number of users possible with the available financial and water
resources. This requires that the most economically efficient option
selected.
 Environmental (Ecological) sustainability: Ecological sustainability
requires that aquatic ecosystems are acknowledged as users and that
adequate allocation is made to sustain their natural functioning.
17

18. Objectives of IWRM
 The main objective of IWRM is to establish a balance between the existing natural
functions of the water resource system and the development aspects of the system.
 Management actions should fulfil the expectations of the society for industrial use
,recreation, nature management and agriculture purpose.
 Primarily coordination of multiple activities and resolving conflicts, particularly those
stemming from negative externalities are the key functions of integrated water
resources management.
 Those activities involve financing and development of infrastructure in a manner that
ensures sustainability of the ecosystem and therefore water.

21. Models for Integrated Water Resources
Management
 Streamflow Synthesis & Reservoir Regulation (SSARR)
 SIMYLD-II
 Interactive River Aquifer Simulation (IRAS)
 European Hydrological System (SHE)

22. Impact of Climate Change on Water
Resources Management
 According to the past research of the Lattenmaier et.al.,1996 Global concentrations of
carbon dioxide have increased by about 25% since the industrial revolution and are
expected to double within about next 80 years.
 Global Warming is directly or indirectly affect the precipitation, snowmelt, volume and
peak for hydrograph as well as peak of runoff, recharging of ground water.
 Hydrological processes change due to global warming and climate change so it is
directly affect the river basin management.
