The document discusses MRC's Decision Support Framework (DSF), which is a suite of computer models and tools used to simulate the Lower Mekong Basin river system and predict the environmental and socioeconomic impacts of development changes. The DSF includes hydrological, simulation, and hydrodynamic models as well as impact analysis tools. It was developed to provide an analytical basis for determining sustainable resource use and planning decisions in a transparent way that encourages cooperation. The DSF helps assess the impacts of changes on both the river systems and communities living in the Lower Mekong Basin.

 What is MRC’S DSF/Toolbox ?
 Why MRC’S DSF is needed?

What is Decision
Support Framework
(DSF) ?

4. By understanding and being able to predict the
behavior of the river system under changed
conditions in the future, MRC can determine:
Appropriate “rules” to safeguard the
environment and riparian interests
 Plans that make best use of the
water resource system within these
constraints

5. What is the Decision Support
Framework?
 A suite of models SHARED by all
member countries with capacity
building and support in their use
 Able to simulate behavior of the LMB
river systems under different
development conditions
 Assist in predicting environmental and
socio-economic impacts as a result of
changes in those conditions

6. Three main computer models to simulate
the system:
Hydrological model
(Sediment and WQ)
Simulation model

together with a set of impact analysis tools
as well as TRANSFER Tool for linking other
models (WUP-FIN 3D-EIA, HEC etc.)

Why Decision Support

needed?

11. Informal Donor Meeting, 26 Aug 04, Vientiane 11
The 1995 Agreement provides a clear framework for
cooperation in development and management of the
Basin’s water and related natural resources
The Agreement sets goals of socio-economic development,
environmental protection and inter-dependent regional
growth
Establishment of water utilisation rules and a rolling Basin
Development Plan are key instruments In implementing
the Agreement

12. Informal Donor Meeting, 26 Aug 04, Vientiane 12
The Decision Support Framework has been developed to:
n Provide an analytical basis for determining equitable use,
sustainable limits and planning decisions …
n … in a manner to encourage mutual trust and
cooperation through transparency and replicability

13. Informal Donor Meeting, 26 Aug 04, Vientiane 13
The Decision Support Framework has been developed to
(continued):
n Assess the impacts that change has on the water
resource system …
n … and in turn to help assess the impacts that changes
have on the natural environment and on the socio-
economy of the LMB
