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)

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

8. Land Development– Erosion & Sedimentation Uncontrolled Land Development

9. Urbanization – Flooding

10. Solid Waste - River Pollution

11. Effluent Discharge - Water Pollution

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.)

15. MISI, VISI & OBJEKTIF IRBM MISSION, VISION & OBJECTIVES MISSION “To manage water resources, river basins, flood risks and coastal zone to achieve environmental sustainability and enhanced quality of life.” “To inculcate GIS culture for efficient and effective service delivery by 2020“ VISION • 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 OBJECTIVE

20. River Basin Geospatial Information Data Collection • Engineering Surveys of river • Alignment, Centre line, Banks • Longitudinal sections • Cross-sections • Reserve / ROW • Topographical Map • Cadastral Map • Satellite Images • DEM (liDAR or IFSAR) • Structures (Dam, Bed Control, Barrage, Gates, log boom etc.) • Hydrological Stations (water level, rainfall) • Water Quality Stations (DID, ASMA)

23. 1 STATE 1 RIVER–CONCEPT OF MINI IRBM 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

36. Application of Geospatial in River Management The way forward

37. What Next ? River Basin Monitoring • 5 urgent projects to use geospatial data for DSS • Sg. KlangRoL Project • Sg. Muar Basin • Sg. MudaBasin • 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.
