|Abstract:||Recent progress in remote sensing is promising significant advances in fluvial sciences particularly in the study of small and medium rivers. Indeed, sensor resolutions are markedly Improving Malthus Allowing for narrower channels to be imaged and acquisition frequencies for airborne methods aussi Have Improved Malthus Allowing for multi-annual surveys. Indeed, sensor resolutions are improving markedly thus allowing for narrower channels to be imaged and acquisition frequencies for airborne methods have also improved thus allowing for multi-annual surveys. Furthermore, satellite data can now be complemented by catchment scale high resolution airborne imagery Orthorectified Often Collected by national agencies: such as the IGN. Furthermore, satellite data can now be complemented by catchment scale high resolution airborne orthorectified imagery often collected by national agencies such as the IGN. Data acquisition can now be Planned on a multi-annual BASIS and ranks of Acquired from a standard survey platforms: such as aircraft, helicopters, ultralight aircraft or unmanned aerial vehicles (UAVs). Data acquisition can now be planned on a multi-annual basis and acquired from a range of platforms such as standard survey aircraft, helicopters, ultralight aircraft or unmanned aerial vehicles (UAVs). The aim of this paper is to Illustrate progress in this field with a series of examples. The aim of this paper is to illustrate progress in this field with a series of examples. Using Both satellite data (SPOT, Landsat and QuickBird) and UAV data, the paper examines a Will ranks of temporal and spatial scales from river Reaches Exceeding ten kilometers to smaller Reaches Where human impacts Have Been Diagnosed. Using both satellite data (SPOT, Landsat and QuickBird) and UAV data, the paper will examine a range of temporal and spatial scales from river reaches exceeding ten kilometres to smaller reaches where human impacts have been diagnosed.|
