What is Decision Support Framework (DSF) ?

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

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

Three main computer models to simulate the system:

Hydrological model (Sediment and WQ)

Simulation model (Sediment and WQ)

Hydrodynamic model (Sediment and WQ)

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

Time-Series Analysis Tools:

- Low Flow Analysis

- Flood Frequency Analysis

- Probability Exceedence

- …..

Impact analysis tools

Spatial Analysis Tool:

- Delta Mapper

Why Decision Support Framework (DSF) is needed?

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

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

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
