General Summary

dsc00311The Stakeholders Workshop for JCOMM-CHy Coastal Inundation Forecasting Demonstration Project (CIFDP-BSW)
 was opened at 1000 hours in the conference room of the Bangladesh Meteorological Department (BMD), Dhaka, Bangladesh, at the kind invitation of BMD.  Dr Arjumand Habib, Director of Bangladesh Meteorological Department (BMD) and the Permanent Representative of Bangladesh to WMO, welcomed all participants from national agencies and the Project Steering Group. In her opening remark, she emphasized the importance of this timely initiative of CIFDP to protect life and property in the coastal zones of Bangladesh, and urged all participants from Bangladesh and from the Project Steering Group to make utmost efforts to achieve the goal in close partnership.

 The objectives of workshop included:

  • clearly defining the roles of national stakeholders participating in the project implementation, for a Definitive National Agreement; and,
  • collecting and review stakeholders’ needs and requirements, for detailed design of the Bangladesh sub-project proposal to funding agencies.

The Stakeholders Workshop involved more than 50 participants including members of the Project Steering Group and other international experts as well as a large number of stakeholder agencies in Bangladesh, including the Bangladesh Meteorological Department (BMD), Bangladesh Water Development Board (BWDB), Cyclone Preparedness Programme (CPP), Disaster Management Bureau (DMB), and Bangladesh Coast Guard (BCG), Regional Integrated Multi-Hazard Early Warning System For Africa and Asia (RIMES), and many others. 

All participants, under the guidance of WMO and the Project Steering Group (PSG), actively discuss on the current status of coastal inundation forecasting/warning in Bangladesh, and on the required development and general direction in implementing the CIFDP National Sub-Project in Bangladesh (CIFDP-B). As the final outcome of this workshop, a Definitive National Agreement (DNA) and Terms of Reference for the CIFDP-B National Coordination Team (NCT) were agreed by all participating stakeholders. The Project Steering Group (PSG) and all participants also agreed on the work plan for the first year of the National Sub-project (CIFDP-B). 

The Workshop, with satisfaction of all national stakeholders participating in the discussion, closed at 17.00 hours on Thursday 1 December 2011.

CIFDP-B General Direction


Participants in the Workshop agreed on the general principles for the implementation of the CIFDP-B as following:

  • The direction of the project will evolve along with the progress of the project.
  • Both institutional agreements (Definitive National Agreement through MoU) and technical development should be carried out in parallel, and be initiated as soon as possible.
  • The project should start and be implemented from what is presently available in the country and region, while ensuring the possibility/flexibility to plug-in updated/modified modules for each component along with the technical development.
  • A small dedicated team of technical experts should be identified by each of the technical partners within the NCT, to carry out the technical development on:
    • improvement/creation of datasets
    • identification of the best-suited models for Bangladesh
    • improvement of (operational) model characteristics and mode of operation
    • model validation and historical dataset building
  • For each model/module development, the NCT/Technical Team should make sure to document the “procedure / best practice” for operation (e.g. optimum run time / resolution / operation cycle)
  • General coordination of the work by NCT will be led by BMD, and by a major leading role by BWDB under the agreement within the NCT.
  • Throughout the project implementation, the NCT will ensure the consideration of the end-user perspectives through the Stakeholders (defined in the ToR of NCT).

Key Elements for Technical Development in CIFDP-B

The Workshop identified the key technical elements to be considered in the implementation of CIFDP-B, as following:

  • Improvement/creation of datasets
    • Digital Elevation Model (DEM) + Bathymetry – Survey of Bangladesh
      • Provision for 10m resolution DEM by 2014/2015. In the meantime, the best available dataset will be used.
    • MetOcean input (in real time and hindcast) - Bangladesh Meteorological Department
    • Water level data, (in real time and hindcast), data on infrastructure - Bangladesh Water Development Board
    • Inundation extent and depth (in situ and satellite)
    • Socio-economic data - Bangladesh Bureau of Statistics
  • Identification of the best-suited models for Bangladesh
    • Among currently operated models, such as IIT-D storm surge model, MIKE-11
    • Consider other available models possible to be operated in Bangladesh, such as MRI storm surge model, SLOSH, ADCIRC, DHI, and others
    • To consider both “solution for NOW” as well as “solution for FUTURE” involving sophisticated but not yet operational (in Bangladesh) models
    • BMD (staff trained at IIT-D), Hydrological agencies (staff to be identified by FF&WC), RIMES
  • Improvement of (operational) model characteristics and mode of operation
    • Improve coastal inundation forecasting by coupling tides, storm surges, and river flood forecast models
    • Develop optimum mode of operation (run time, etc.)
    • Consider allowed runtime for operation (based on required response time and selected method)
    • Consider move toward pre-run look-up table
    • BMD (staff trained at IIT-D), Hydrological agencies (staff to be identified by FF&WC), RIMES
  • Model validation and historical dataset building
    • Validate models in set of historical storms (hindcast)
    • Assess forecast performance (errors and uncertainty in forecast), as guidance for development for users
    • Build historical dataset
      • Identify past inundation cases (e.g. Cyclone Sidr, Aila)
      • Collect the best possible dataset on inundation
      • Collect satellite imagery (e.g. UNOSAT archive)
    • Coordinate with the UNDP-CDMP project on Multi-Hazard Risk Vulnerability and Assessment Modelling and Mapping

CIFDP-B Timeline / Activities for Year-1

The following timeline and milestones were proposed by the Workshop, with the key target of a progress review by the NCT and the PSG in December 2012:

  • PSG to provide outline of the concept and plan for CIFDP-B, based on the CIFDP Implementation Plan: January 2012
  • Technical Partners of NCT to identify members of the dedicated team for technical development: January 2012
  • Technical development team / NCT to complete the plan of action for Year-1: February 2012
  • BMD, with cooperation/assistance by NCT members, to get the MoU signed by 1 June 2012
  • NCT and PSG to compile and submit funding proposals: December 2012
  • PSG and NCT to review progress: December 2012
