CONTENT
  • Role of WMO in Hydrology and Water Resources
  • Objectives of WMO in Hydrology and Water Resources
  • Flood-related Activities
  • Other WMO Programmes
  • Conclusions
slide3
ROLE OF WMO IN HWR
  • Safety of life and property
  • Information and knowledge in support of Integrated Water Resources Management
  • Capacity building
  • Support for knowledge based operations and policies
  • Promotion of risk management approach
slide4
OBJECTIVE OF WMO IN HWR

To apply hydrology to:

  • meet the needs for sustainable development and use of water and related resources;
  • the prevention and mitigation of water-related disasters; and
  • ensure effective environmental management at national, regional and international levels.
slide5
FOCUS OF WMO IN HWR
  • The measurement of basic hydrological elements form networks of hydrological and meteorological stations
  • The collection, processing, storage, retrieval and publication of hydrological data
  • The provision of hydrological data and related information for use in planning and operating water resources projects and monitoring the status of water resources
  • The provision of effective flood forecasting and warning services
slide6
COMPONENTS OF THE HWRP
  • Basic Systems in Hydrology
  • Forecasting and Applications in Hydrology
  • Sustainable Development of Water Resources
  • Capacity Building in Hydrology and Water Resources
  • Water-related Issues

slide14
GLOBAL/REGIONAL SHORT-TERM HYDROLOGICAL FORECASTING SYSTEM

RECOMMENDATIONS

  • The tools should be tested in different river basins (in particular, in an arid/semi-arid region);
  • Preference should be given to river basins that are multi-national;
  • The role of the NHSs and other stakeholders must be recognised and maintained
  • The involvement of relevant WMO Regional Association Working Groups on Hydrology should be sought; and
  • Possible river basins include: the Limpopo, Lake Victoria, a river basin in West Africa, the Mekong, Central America, the Niger and the Oka.
slide15
GLOBAL/REGIONAL SHORT-TERM HYDROLOGICAL FORECASTING SYSTEM

STEPS/STAGES

  • A compilation of the approaches (QPE, QPF, etc);
  • A study identifying in greater detail the strengths and weaknesses of the approaches;
  • A comparative testing of targeted elements of the forecast capability;
  • Development of a prototypical composite system or systems; and
  • Preparation of project packages for funding (including a needs assessment).

Modelling

    • Spatially distributed, event-based
    • National system - scaleable
  • Hydromet Inputs
    • Quantitative radar rain
    • NWP, QPF
  • Web Products
    • Maps and data bulletins
    • Updated hourly – daily
RECENT DIRECTIONS
single most important action
Single Most Important Action?
  • Community education, engagement & awareness – participation, empowerment, ownership. People should be made aware of their personal risk
  • Improved agency coordination – national consistency/national agency, improved agency coordination framework
  • Better risk communication – incl. use of technology, radio/media accessibility
slide18
CONCLUDING REMARKS
  • WMO is doing a lot in its areas of expertise
  • Where should we target future initiatives?
  • Any flood forecasting system is only as strong as its weakest link – how do we involve all of the stakeholders?
  • Stress the need for greater collaboration between NHSs and NMSs in flood forecasting
  • Look forward to the presentations and discussions from this week to futher define and refine the HWR work plan
