CHy Focus Area: Hydrological Applications, Products and Services

The AWG members will, with support from OPACHE experts as required, maintain responsibility for the following activities:

  1. WRM and drought: develop and/or recommend tools for water resources assessment and planning to assist decision-making including under climatic variability and change, such as preparing guidelines for assessing hydrological drought severity and impacts for water resources management, possibly through the use of hydrological drought indicators. This could be achieved through the establishment of a Community of Practice on Droughts;
  2. Global Hydrological Status and Outlook: Oversee the establishment and work of the expert Task Team coordinating the pilot phase of the initiative;
  3. Seasonal Hydrological Prediction (SHP): follow and summarize the development of the usability of climate sub-seasonal to seasonal to inter-annual forecasts (including RCOFs outputs) for hydrological and water resources management applications (link with the Couple Hydrology-Atmospheric Modelling and Prediction (CHAMP) project and SASCOF SHP demonstration), assisting in building interfaces to water users (agriculture, energy production, health, etc.);
  4. DRR: contribute to the development of identifiers for cataloguing of hazardous events (promote hydrological perspective) and lead the finalization of the Manual on Flood Risk Mapping, including investigating the applicability of Common Alerting Protocols (CAP);
  5. Implementation Strategy for the End-to-End Early Warning Systems (E2E EWS) for flood forecasting (using the Community of Practice approach): develop assessment guidelines for NHSs to evaluate their E2E EWS for flood forecasting, furthering the earlier work on “Efficiency of flood forecasting services” (including testing developed procedures) possibly through the establishment of a Task Team/Working Group, consistent with the FFI-AG Work Plan of 2016–2019, develop access to the interoperable technologies including platforms and models for use in flood forecasting; provide access to training and guidance material, in conjunction with item (g) below, on the aforementioned items; and assist in the development of projects;
  6. FFI: ensure that all major projects under FFI (CIFDP, FFGS, SWFDP) include the requirements and reflect best practices for effective and sustainable flood forecasting, including urban areas, consistent with the FFI-AG Work Plan of 2016–2019. Co-chair the Project Steering Group (PSG) of CIFDP, participate in CIFDP sub-projects, coordinate closely with OPACHE member(s) participating in CIFDP and similarly contribute to the SWFDP and other projects/activities, ensuring improved flood forecasting early warning systems;
  7. APFM: work with APFM on provision of guidance and training material on E2E EWSs for Flood Forecasting through the IFM HelpDesk, and other topics such as preparation of guidelines on how to formulate numerical weather prediction information for use in flood forecasting, consistent with the FFI-AG Work Plan of 2016–2019. Represent CHy on the APFM AC/MC meetings.
