  19. Objektif Projek • MembangunkanSistemRamalandanAmaranBanjiruntukLembanganSg. Klangberdasarkan data semasa

  20. JadualPerlaksanaan • Tahun 1 • Supply, Install, Testing and Commissioning hydrological instruments at RTUs and establish the control centre • Develop the Operation System for Control Centre and RTUs • Develop the flood forecasting model • Tahun 2, 3, dan 4 • Operational and maintenance • Model calibration and system fine-tune • Continuous training

  21. Butiran Projek • Contractor Name : ST DOT COM SDN BHD • Date Start: 13 July 2007 • Date End: 12 July 2008 • Date Start (Warranty) : 13 July 2008 • Date End (Warranty) : 12 July 2011 • Date End (Extended 1) : 30/11/2008 • Date End (Extended 2) : 31/01/2009 • Date End (Extended 3) 21 April 2009 • LAD (217*RM 500/day) : RM 108,500 • CPC : 25 Nov 2009 – 24 Nov 2012 • Date Start (Warranty – Extended): 22 April 2009 • Date End (Warranty – Extended): 20 April 2012 • Project cost : RM 25,406,200.61 Contract JPS/IP/H/1/07

  23. Sebab-Sebab (EOT1 dan EOT2) • Kelewatan pemberian tapak kepada Kontraktoruntuk 88 stesen, sepatutnya sebelum 12 Oktober 2007. Mula pemberian tapak utk 23 stesen pada 9 Jan 2009 • sehingga 12 Julai 2009 sebanyak 11 tapak masih belum diberikan dan tarikh terakhir pemberian tapak pada 28 Nov 2008. • 30 tapak ditebing sungai – perlu kerja ukur • tapak dikawasan agensi kerajaan dan swasta. • Masalah pemendapan tanah dan sampah – perlukan masa untuk baikpulih stilling well.

  24. Arahan Perubahan Kerja (VO) (EOT1, EOT2 dan EOT3) • Kerja tambahan diluluskan Kem. Kew pada 4 September 2008 : • Peralatan • Perisian • Skop kerja baru dimuktamadkan oleh Lembaga Perolehan pada 16 Jan 2009 • Kerja ukur (53 lokasi) • Sistem sekuriti Pusat Kawalan • Sistem Komunikasi Pusat Kawalan

  25. KomponenProjek • 88 new telemetric stations : • Rainfall (76) • Soil Moisture (36) • Water Level (52) • Water flow (5) • Water Quality (29) • Meteorological (3 ) • Open architecture System • 1 Control Center • 3 sub-control centre

  26. RTUs Station

  27. Pulling data from external sources JabatanMeteorologi Malaysia • Numerical Weather Prediction Models for QPF • lead time of 4 -8 hours lead time from RaDAR and 8 -36 hours from satellite

  28. 2. Stormwater Management And Road Tunnel system (SMART) 28 telemetric stations which consist of rainfall, water level and flow data. All SMART data will be integrated into the new system on real-time. Data will then be fed into the forecasting model

  29. Anti-vandalism measures for RTU • Fencing and housing • Motion Detector • CCTV • Siren • Automatic Locking Mechanism

  30. OUTPUT

  31. 88 new telemetric stations : • Rainfall (76) • Soil Moisture (36) • Water Level (52) • Water flow (5) • Water Quality (29) • Meteorological (3 ) • Open architecture System • 1 Control Center • 3 sub-control centre

  32. Forecasting Model • Produces forecasts in real-time • Can use observed data to improve its forecasts (‘updating’)

  33. SYSTEM OUTPUT Flood Maps • Forecast water level depth and flooding location • Forecast flood map location • Flood Risk Map (based on ARI) • Water quality monitoring • River Erosion and Sedimentation • Monitoring • Debris & mud flow forecasing • Drought Index & monitoring system Flood Risk Map

  34. FLOOD WARNING Flood Classifications • At each flood warning river height station, the  severity of flooding is described as minor, moderate or major according to the effects caused in the local area or in nearby downstream areas.
