This paper presents the results of a survey of an estuary in Senegal since a human-induced breach was opened in a bar at the mouth of the embayment in October 2003 to reduce the effect of a major flood event. The evolution of the new mouth's width has been analysed using a Landsat time series of 94 scenes, covering the period 2003-2010. This series is complemented by recent high resolution Alos-PRISM data, and very high resolution Ikonos data. The AA. focus on the consequences for the new mouth and the surrounding coastline. Methodological conclusions are also presented, regarding the potential role of remote sensing in surveying estuaries
