DESCRIPTION:Dr Alain Recking\, Researcher at Irstea\, Grenoble\, France\nB
 edload conditions the development of river morphology along different spac
 e and time scales\; however\, by concentrating the flow in preferential pa
 ths\, a given morphology controls bedload for a given discharge. As bedloa
 d is a non-linear response of shear stress\, local morphology is likely to
  have a strong impact on bedload prediction when the shear stress is avera
 ged over the section\, as is usually done. We will see how taking into acc
 ount the river morphology can help to improve bedload prediction. But on t
 he other hand\, predicting the morphology also requires predicting the siz
 e of the transported material\, and from this point of view\, we will disc
 uss the limitation of available computational methods in a morphodynamics 
 perspective.\nBio :\nAlain Recking is researcher in the Torrent Erosion an
 d Snow Avalanches group at Irstea\, in Grenoble. His research focuses on f
 luvial-hydraulic processes in gravel- and cobble-bed channels\, including 
 grain sorting and feedbacks between flow hydraulics\, sediment transport\,
  and morphodynamics. He teaches every years Hydraulic and Sediment Transpo
 rt in several Universities  as well as for staffs of several government a
 gencies.
