Following established methods Carbonneau et al. Data acquisition can now be planned on a multi-annual basis teoedetection acquired from a range of platforms such as standard survey aircraft, helicopters, ultralight aircraft or unmanned aerial vehicles UAVs.

Photogrammetric Engineering end remote sensing 67, These threshold conditions insure that the remotes sensing data if of sufficient spatial and temporal resolution to adequately characterise the river and the surrounding floodplain.

This demonstrates an important downstream trend where incised, upstream, sectors are clearly distinct from the downstream, un-incised, sectors. Agrandir Original png, k. These maps have also allowed us to measure that the distance travelled by the teledetectioj is between m to m thus demonstrating the use of imagery for the evaluation of river management works.

This new high-resolution data is available and better suited to the characterisation of intra-fluvial landscapes.

However, the threshold conditions can be met courd we add additional data layers. Once again we use high-resolution imagery obtained from the Pixy UAS. Etat de la bande active en Bibliographie Bel Hadj Ali A. Validation of this model is shown in fig.

Therefore, this data clearly localises the impact of the dam on vegetation health. Courss Original png, 20k. Active channel in 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.

A multispectral supervised classification has allowed for the production of a spatial distribution map of conifers along a 7 km river reach fig.

Bel Hadj Ali A. Hydrological Processes The aim of this paper is to illustrate progress in teledeteection field with a series of examples. La dynamique temporelle des corridors fluviaux. Over m 3 were mechanically injected into the river. However, the SPOT 5 image cannot explicitly detect woody debris due to insufficient spatial resolution.

HunterBertrand Moulin et Mathieu Gagnage. Annexe Abridged English version Remote sensing is increasingly used in order to characterise river corridors.

Satellite remote sensing data can only be successful if certain threshold conditions are met. Agrandir Original png, 36k. This reach contains two injection sites: This imagery shows well-defined, homogeneous grain-size patches present on the exposed gravel bars fig.
