2. Definition of River and River Basin
“River” means any river, stream, creek or other natural water course, and/or any tributary, distributary or artificial deviation thereof
(National Land Code 1965)
“River Basin” means the area of land from which all surface runoff flows through a sequence of streams, rivers and possibly lakes into the sea at a single river mouth, estuary or delta
(European Union Water Framework Directive 2000) 2

3. RIVER BASIN

4. Definition of River “Rehabilitation”
To bring back river to its original condition (back to nature) with a healthy eco-system
Multi-action and steps to recreate the dynamic balance and function of the river to a sustainable state

5. River Rehabilitation Objectives
To restore natural water quality
To restore flow regime
To restore channel stability and geometry
To restore riparian community of life
To restore vegetation and aquatic life

12. The Need for an Integrated River Basin Management (IRBM)

13. INTEGRATED RIVER BASIN MANAGEMENT (IRBM)
“The process of coordinating conservation, management and development of water, land and related resources across sectors within a given river basin, in order to maximize the economic and social benefits derived from water resources in an equitable manner while preserving and, where necessary, restoring freshwater ecosystems.”
(Adapted from Integrated Water Resources Management, Global Water Partnership Technical, Advisory Committee Background Papers, No. 4, 2000.)

“To manage water resources, river basins, flood risks and coastal zone to achieve environmental sustainability and enhanced quality of life.”
VISION
“To inculcate GIS culture for efficient and
effective service delivery by 2020 “
provide an integrated framework for planning and management of water resources
facilitate decision making on water resources and water resources related issues
enhance the awareness of the trends & potential benefits on water resources management

River Mapping
i. Identify sources of pollution
Monitor Water Quality Index at regular intervals
Form River Monitoring Committee
Identify responsibilities of each department to control river pollution
v. Each department bid for allocation to overcome river pollution problems

37. What Next ? River Basin Monitoring
5 urgent projects to use geospatial data for DSS
Sg. Klang RoL Project
Sg. Muar Basin
Sg. Muda Basin
Sg. Damansara Sub-Basin
Sg. Selangor Basin
Progress Report under Geospatial Steering Committee at NRE Ministerial Level

38. River Basin Monitoring
Activities in the river basin / catchment
Land use changes
Development activities
River corridor illegal encroachment, Squatters
Deforestation
Sand Mining
Pollution discharge
Changes in water quality

39. Conclusion
River as a valuable asset to the country (not a liablity) should be well managed, conserved and rehabilitated from time to time.
Geospatial data capturing the location and ground condition is a very useful information tool that helps in making sound decision within a river basin.
