The example follows the progress of this sediment through a 5 km reach. Photogrammetric Record 16, Characterisation teledetectuon alluvial plains by remote sensing: In order to offset this limitation, field surveys were conducted in order to localise woody debris.
Tools in Fluvial Geomorphology. Agrandir Original png, 17k. Deux exemples illustrent ces propos. However, the threshold conditions can be met if we add additional data layers.

In order to assess antecedent structures, dendrochronological surveys were required. Geomorphology 55, La dynamique temporelle des corridors fluviaux. When satellite data is unsuitable, airborne images can be used fig.
The spatial resolution of the sensors must be adapted to the detection of river and flood plain features e. Hydrological Sciences Journal First, we discuss the lower Ain valley.
Landsat 7 TM data is used to examine the impact of a series of hydropower dams on the growth rates of riparian vegetation. Agrandir Original png, 86k. Therefore, this data clearly localises the impact of the dam on vegetation health. Furthermore, the temporal acquisition rate of data must be capable of sampling rapid change, sometimes on the order of a few hours post-flood.

Remote Sensing of the Environment 43, Using well-established methods Carbonneau et al. Paper presented at the Braided Rivers Conference, Br.
HunterBertrand Moulin et Mathieu Gagnage. Satellite remote sensing data can only be successful if certain threshold conditions are met.
Applied Optics Active channel in Earth Surface Processes and Landforms 31, In recent years, new satellite data has begun to offer data on metric e. These threshold conditions insure that the remotes sensing data if of sufficient spatial and temporal resolution to adequately characterise the tleedetection and the surrounding floodplain.
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.
Following established methods Carbonneau et al. Remote Sensing of Environment Water Resources ResearchArticle No. For example, we discuss a study of morphological change following a sediment management program aiming to redress the reach scale sediment deficit resulting from the construction of dams. These field surveys confirm the presence of favourable conditions to the presence of woody debris fig.
