  Welcome to the Course "Assessment of National needs and capabilities in End-to-End Flood Forecasting and Early Warning Systems", a joint activity of the WMO Capacity Development Pannel (CDP) and the Hydrological Coordination Panel (HCP).
  This will be our way of communicating until we meet in person at Facultad de Ingeniería y Ciencias Hídricas of the Universidad Nacional del Litoral, one of the components of the WMO Regional Training Centre (RTC) in Argentina, in Santa Fe city, from September 12 to 15.
  In this part of the training, we will focus on the concepts that we need to handle for becoming an evaluator for assessing the national needs and capabilities in End-to-End Flood Forecasting and Early Warning Systems (E2E FFEWS) of a country.
  In this Moodle you will find:
  Who the trainers will be
  How WMO is working on Hydrology and Water Resources
  Which the WMO main programmes and activities in Hydrology are
  What the Associated Programme on Flood Management is
  How WMO Assessment Guidelines was born, and the objectives and purpose of the training
  Which the main concepts of Flood Forecasting and Early Warning System are
  and finally examples of Flood Forecasting and Early Warning System in some countries.
  
  We hope you find this material suitable, and we wish see you in September in Santa Fe, Argentina.

Flood Forecasting and Early Warning System
- The next two sections introduce us to the elements that we must consider when we are dealing with flood forecasting and early warning system, such as type of river basin; physical processes; types and causes of floods; type of service; forecast lead time; data requirements; infrastructure and human resources; and also to their fundamental considerations (structure of flood forecasting and warning system; components of flood forecasting and warning systems; meteorological and hydrological considerations; nature of risks and impacts; institutional and legal aspects; dissemination of forecasts and warnings; the role of flood forecasting in flood management).
  These concepts will help us to work with the tools developed to assess the status and needs of a National Hydrological Services.
- Main aspects of Flood Forecasting Systems Book
  
  The recognition of the need for flood forecasting and warning systems is witness to the reality of the limitations of structural and non structural flood protection systems. Due to the existence of settlements in flood-prone areas and to the need to meet present-day expectations of community safety and protection of assets, the provision of an adequate flood forecasting and warning service is a growing necessity in many countries.
  To design a suitable flood forecasting service, it is necessary to understand:
  (a) The hydromorphological characteristics of the basin, topography, geology and soils, and the degree of structural development;
  (b) The main physical processes occurring during hydrometeorological events;
  (c) The type of service that is required or can be achieved technically and economically.
  Items (a) and (b) are matters relating to the physical conditions of the catchments concerned, whilst item (c) concerns organizational and operational considerations. Each point will be examined in the following subsections.

- Fundamental Considerations of Flood Forecasting and Warning Systems Book
  
  The problem of floods occurs throughout the world, in regions with diverse climates (from very humid to desert) and affects both developed countries and countries with a lesser degree of development. Therefore, a National Hydrological Service should be prepared for it. This item describes some of the fundamental considerations when dealing with flood forecasting and early warning systems.
