CIEE’04
PREAMBULE
Perpetuating its tradition, the Higher National School of Hydraulics
organizes this international meeting on water and environment al issues. The
context of this conference reflects firstly the willingness of the academic
community to address issues of water shortages and environmental pollution by
consultation approaches and discussions with professionals, researchers a nd
decision makers to solve this crisis that threatens our future and survival.
Only concrete actions and the proposal of solutions to establish good
governance approaches and strategies for sustainable development especially in
the developing countries can be adopted. This is one of the reasons why
governments and society need to confront the challenges by harmonious
approaches, supported by cooperation between countries that can implement
integrated strategies of water and environment management.
In this context, five themes were chosen to be developed and discussed
during this conference:

Management techniques of drinking water and sanitation systems.

Sea water desalination.

Basin hydrology (modeling, flood, drought).

Management of irrigation systems.

Resource and environmental protection.
It should be noted that the communications gathered in the proceedings are
selected after assessment, and have an undeniable scientific interest, because
they are mainly related to the main fields of the various themes mentioned
above. They aim, in a concrete way through the presentations and discussions
that will take place during this work, to give a contribution and propose
solutions to problems related to the mobilization, management and protection of
water and environment.
We hope that this conference will be marked by a willingness to conceal
any speech or academic discussion on the water crisis and the issues related to
the environmental protection through the development of concrete actions by
the implementation of solutions thanks to effective cooperation and solidarity of
specialists,
in an objective of preserving the vital commodity «blue gold», promoting the
integration of the principles of sustainable development of natural resources in
accordance with the Rio Declaration and the action program of the 21st century
(Agenda 21 ).
At this occasion, we would like to pay tribute to all communicators, who
wanted to participate in this scientific event. At the same time, we express our deep
gratitude to the members of the scientific committee, who kindly agreed to assess
communications and
provide their assistance and advice to the success of this
meeting. We would like to thank all of our sponsors for their financial support, without
which we could not organize this meeting.
We express our gratitude to our colleagues and wish them a pleasant stay.
Convinced by the exchanged ideas and information that will undoubtedly meet the
challenges.
Finally, we invite all players in the water and environment sector to
combine their efforts by exchanging information and we encourage the organizers of
this type of scientific events.

RECOMMENDATIONS
After discussing these issues, on the basis of introductory presentations,
the following conclusions and recommendations were achieved
A. concerning the prevention of the silting up of dams:
Considering the fact that the natural phenomenon of sedimentation in
dams is a technical, socio economic and ecological concern, which
requires an integrated management to reduce its impacts, the participants
recommend the following actions:
1. Identify, on watersheds, areas in need of protection according to
the degree of soil erodibility. This step will allows us to develop
tools for estimating erosion as well as integrated anti-erosive
measures (soil protection and restoration, reforestation species
selection, agricultural practices, torrent control, etc. …).
2. Develop research on representative basins for developing
assessment models of sediment transport, taking into account the
specific features of the semi arid Mediterranean regions.
3. Deepen the knowledge of the processes of distribution,
settlement and consolidation of the sediments transported and
deposited in dams. The modeling of these processes would help
to improve the efficiency of the dredging and disposal systems of
sediment deposits.
4. Correlate periodically the bathymetric surveys in reservoirs
with predictions of the sediment formed during the dam study
phases.
5. Develop actions to rehabilitate dams, using the most efficient
dredging techniques in terms of water and energy consumption.
B. concerning the reuse of wastewater:
Considering that the imbalances between the available conventional water
resources and the evolution in water demand requires the integration of non
conventional resources in the water balance, and taking account of technical
progress in the world and especially in some Mediterranean countries as
regards the reuse of wastewater, the participants recommend the following
actions:
1. Implement pilot projects at the decentralized level and that, on the basis of
an inventory of sites with favorable conditions of reuse, especially in
terms of management of sewer and wastewater treatment systems.
2. Promote the reuse of wastewater for watering five green spaces, nurseries
and ornamental crops as well as in industry.
3. Capitalize the operating results of the pilot projects for the production of
technical and sanitary standards, on the basis of a multidisciplinary
monitoring of activities.
4. Develop, as the same time as experimentation, a strategy to upgrade the
management of sewer and wastewater treatment systems and to protect
natural environment, in a view of a controlled exploitation of treated
water in terms of health and ecological risks.
C – Concerning the wastewater treatment techniques,
The participants examined especially the benefits of lagoon-based wastewater
treatment process. Given the diversity of the existing treatment processes, it is
necessary to:
1 – Consider the lagoon as an alternative solution by integrating
technical and economical criteria.
2 – Develop pilot projects at the decentralized level in order to enhance the
monitoring capacities which are locally available at both the university and
the profession.
D – Concerning the rehabilitation of irrigated perimeters,
Participants focused particularly on problems related to water valuation
and soil conservation, at both the perimeters of northern Algeria and
palm groves and development areas in the south.
In this context, the participants recommend to:
1- Systematize the preliminary studies of soil mapping and determination
of technical standards and guidelines for irrigation and drainage.
2- Establish networks to measure hydrodenamic characteristics in the
irrigated development areas in order to observe the phenomena of soil
evolution and establish measures for land improvement.
3- Reactivate the hydro agricultural research and experimentation by
mobilizing the research capacities available in the various regions of
the country.
CONCLUSION
Recognizing the urgent need to build bridges of technological
development between research, university and profession;
Convinced that the synergy between the research themes and
water resource development projects and programs is a decisive factor
for the development of technical solutions adapted to the specific
characteristics and needs of the Mediterranean countries and Algeria in
particular,
The participants in the Water workshop of CMEE 2002 express
their joint commitment to work together and develop their working
relationships for social and economic development. They also called on
the authorities concerned to create the organizational and support
conditions able to support the achievement of their common goals and
recommendations resulting from their works.
