Event description
Flooding has the highest frequency of occurrence of all types of natural disasters across the world.Between 2000 and 2015 floods accounted for 39% of all natural disasters. Producing global scale flood forecasts and risk assessments has been made possible in the past 10 to 15 years owing to the integration of meteorological and hydrological modelling capabilities, improvements in data, satellite observations, hydraulic modelling, as well as increased computing power.
There are many organisations in low income countries that operate flood forecasting systems and have produced flood maps. However, these are often for specific locations or river catchments. Global flood models can provide flood forecasts and maps in catchments where currently none are available.
This event will focus on two global flood models:
- The Fathom global flood model which simulates flood extents across all rivers in the world using a two dimensional hydraulic modelling framework.
- The Global Flood Awareness System (GloFAS) which produces probabilistic fluvial flood forecasts with up to two weeks lead time worldwide.
Examples will be given of the use of these systems for various case studies worldwide.
Part of the CIWEM Flood Resilience digital series.
