For at least 20 years, nadir altimetry satellite missions have been successfully used to first monitorthe surface elevation of oceans and,shortly after, oflargeriversand lakes . For the last 5-10years, few studies have demonstrated the possibility toalsoobserve smaller water bodies than previously thought feasible (river smaller than 500m wide and lake below 10 km2). The present study aims at quantifyingthe nadir altimetry performance over a medium river (200m or lower wide) with a pluvio-nivalregime in a temperate climate (the Garonne River, France). Three altimetry missions have been considered : ENVISAT (from 2002 to 2010), Jason-2 (from 2008 to 2014) and SARAL (from 2013 to 2014).< Réduire
