Ouagadougou, Burkina Faso
In Ouagadougou, Burkina Faso, AMMA-2050 is supporting flood-resilient planning using new hydrological mapping models and associated future scenarios fordecision makers at national, regional and local levels, and with national, city-level and mayoral offices. To develop this mapping AMMA-2050 engaged with a group in Montpellier France (IRD who lead the Raincell project in Ouaga) and established a working remote connection to the Athys model developed by IRD. ATHYS (A Telier Hydrologique Spatialisé) is rainfall-runoff transformation model, developed by the Research Institute for Development (IRD) of Montpellier. The basic principles of ATHYS are a hydrological environment for distributed modelling, including a series of models, DEM processing, hydrological and rainfall data and geographical display, spatial data interpolation. The flow generated for a rain event (rainfall-runoff transformation) is calculated for each cell, the amount of rain is estimated by the production model which will contribute to runoff. For the purposes of AMMA-2050, the team are interested in future flows under climate change. AMMA-2050 carried out an initial model scoping and calibration exercise and established a working relationship with IRD and Raincell project, including access to Raincell data for our monitoring period (2016-17).
