with an area of responsibility for planning and managing water
resources defined by the river basin. It has established six Sub-
basin Agencies which carry out delegated functions on behalf of
the basin agency. The River Basin Organization (RBO) design
provides for a River Basin Council which is to act as the main
decision making and coordinating agency for water resources in
the river basin. The Council is to guide the water management
actions of the River Basin Agency (in this case, the Panj Amu
River Basin Agency). As yet, the Council is not formed and thus
the RBO is developing, but not yet fully formed.

Water allocation
Water allocation is the process of sharing water among
groups of water users and individual water users within these
groups. The water users in the groups may be categorized by
the uses to which water is to be applied, such as environmental
maintenance, town water supply, irrigation of annual crops,
irrigation of permanent crops such as orchards, hydropower
and water use in industry and mining. The priority of water use
by such groups is set out in the Water Act.
Water stress can limit land capability, re- duce agricultural
production, and subsequently amplify the volatility of
agricultural commodity prices, adding to challenges in
realizing sustain- able rural community. Water stress can also
in- duce environmental externalities, and these externalities,
in turn, affect economic sectors and the natural environment
significantly (Hoekstra 2014; IPCC 2014). Discourses on water
scarcity are key to shape people's understanding of its causes,
consequences, and interaction among stakeholders (Hussein,
H., Alatout, Feitelson, E 2002).
There are two aspects to water allocation:
1. River basin planning in which water availability is
balanced against water demands over a long time period; and
2. Annual or seasonal water allocation where water demands
are managed to balance against forecast water availability for a
12 month period or shorter.
In both cases, the water balance between supply and demand
must be made for the entire hydrologic unit (usually a river
basin) and must be made at an appropriate time scale (usually
not more than a month) to allow for the variability in water
supply. Water demands need to be separated into different
categories which consider their sensitivity and ability to be
managed when restrictions in supply are imposed. Water supply
estimates need to consider the ability of infrastructure to «time-
shift» water through the use of storage.
Once the balance of supply and demand through the water
season is determined, the management task is to allocate
equitable amounts to water user groups and then to individual
water users within these groups. There are several important
tasks in this management process:
— Informing water users of the water supply and demand
forecasts and the need for management control
— Monitoring the water sharing arrangements, updating
the forecasts, re-calculating the water sharing arrangements
and re-announcing the water shares
— Policing the announced water shares
Clearly the underlying task in this management is
involvement of the water using community and communicating
and gaining agreement to the whole water allocation process.
It is good to have high-quality discharge data available
for our rivers, and meteorological data, but in case of non-
availability or data gaps the studies confirm that satellite rainfall
data can be used as a source of meteorological data which are
important for river basin planning and management studies
(Bl
ö
schl et al. 2013). Even in the recent periods using of the
collected data as remote and satellite precipitation products are
increased (N
