  1. 4th On the Job Training on Operational Flood Forecasting Tank Model Urban Flood Risk Management in a Changing Climate : Sustainable and Adaptation Challenges IrMohdZaharifudinMuhamad Ali Department of Irrigation and Drainage of Malaysia MACAO August. 6 - 10, 2009

  2. 4th OJT Background • Under the Regional Corporation Project Implementation Plan (RCPIP), Malaysia has agreed to conduct (4) four On-the-job Training on Flood Forecasting between TC members (OJT). • The 1st OJT was held from 21 Jan – 28 February 2008, • The 2nd was held on 1 December – 31 December 2008 • The 3rd OJT was held from 21 July – 23rd August 2009. •  The fourth and final OJT was held from 12 July until 6 August 2010 at DID office (Division of Water Resources Management and Hydrology), Kuala Lumpur, Malaysia. • The programme was arranged for 20 days to cover all the modules that have been planned by the DID • The 4th OJT was attended by 18 participants, comprising of 15 DID Engineers and the 3 Typhoon Committee (TC) members (Department of Meteorology and Hydrology Laos PDR, Ministry of Water Resources of China and Ministry of Water Resources and Environment Vietnam).

  3. Johor Flood Dec. 2006 – Jan.2007 (Johor River Basin) 4th OJT Objectives • gain knowledge, appreciation and experience on use of the Tank Model for flood forecasting • configure a flood forecasting model based on the Tank Model for a selected catchment in the participant’s country • calibrate the Tank Model and preparing the model for operational use in the participant’s respective organization • develop expertise in writing simple macros (MSExcel) to automate model computations – a skill which can be used to customize the model and further enhance the model in the future • Technical knowledge sharing among participants

  4. OJT Output • understanding the concept of the Tank Model in simulating flood runoff. • configure and calibrate a Tank Model for a river basin in the participant’s country • develop expertise in simple programming techniques which is useful for future continual enhancement of the model which is to be expected

  5. 4th OJT programme WEEK 1 • WEEK 1 - Introduction to flood forecasting • WEEK 2 – Data processing &VB programming • WEEK 3 – Introduction to telemetry and SCADA system • WEEK 4 – Report and Assessment on the OJT • Flood Forecasting using Tank Model • MSExcel Macros application • Configuring the Tank Model

  6. 4th OJT programme • WEEK 1 - Introduction to flood forecasting • WEEK 2 – Data processing &VB programming • WEEK 3 – Introduction to telemetry and SCADA system • WEEK 4 – Report and Assessment on the OJT WEEK 2 • DataChecking • Data processing • Estimate Catchments parameter • Development of Excel Macros codes

  7. Modules of the 4th OJT • WEEK 1 - Introduction to flood forecasting • WEEK 2 – Data processing &VB programming • WEEK 3 – Introduction to telemetry and SCADA system • WEEK 4 – Report and Assessment on the OJT WEEK 3 • Fine tuning of model • Calibration process • Field visit to SMART control centre • Telemetry and SCADA system

  8. Modules of the 4th OJT • WEEK 1 - Introduction to flood forecasting • WEEK 2 – Data processing &VB programming • WEEK 3 – Introduction to telemetry and SCADA system • WEEK 4 – Report and Assessment on the OJT WEEK 4 • Model enhancements • Report preparation

  9. 4th OJT Result A. China • Huaihe River Basin (HRB) • Catchment area about 2,400km2 (134km length) • The basin divided into 1 sub-basin • Using 6 rainfall station, 2 discharge station and 1 evaporation station The hydrograph outputs on validation (Data from 3th Jun to 19th Sep 2003)

  10. B2 B1 N1 B3 N2 3rd OJT Result B. Vietnam • Ngoi Thia River • Catchment area about 1,652km2 • The basin divided into 3 sub-basin • Using 3 rainfall station, 1 streamflow station

  11. 4th OJT Result C. Loas • Nam Lik Kasi River basin • Catchment area about 5,115km2 • The basin divided into 3 sub-basin

  12. 4th OJT Result D. Malaysia • Dungun River basin • Catchment area about 1,513.5 km2 • The basin divided into 5 sub-basin • Using 4 rainfall station, and 1 streamflow station

  13. Future Planning • Year 2010 is the final year of 5 year Malaysia Plan • Director General of DID Malaysia did not give any instruction on any international commitment due to restructuring of Malaysia Plan for 2011 to 2015. • Next year, the planning of international programme will be done based on approved budget and new policy from Ministry and Government Malaysia

  14. Thank You! The Director General of DID Malaysia, on behalf Malaysia Government send regards to everybody and thank very much to UNESCAP/WMO TYPHOON COMMITTEE AND MEMBERS for the commitment, support, cooperation in OJT project.
