DESCRIPTION:Prof. Dr M. Hervé Piégay\, Géographe\, CNRS - National Cent
 re of Scientific Research\, ENS of Lyon\, France\nSediment replenishment (
 or gravel augmentation) is becoming a popular restoration measure in river
 s affected by a sediment deficit and paved\, notably in the Alps and their
  surroundings. The aim of this talk is to introduce a few examples where t
 his measure has been experimented focusing on feedbacks to learn from thes
 e experiences and promote adaptive management. We will explore the justifi
 cation and the critical questions operators are faced to when implementing
  such actions\, such as the amount of sediment needed\, the frequency of i
 njection\, the design of injection\, the available sediment sources\, the 
 risks associated with such measures and their potential benefits. Some cha
 llenging issues will be introduced in term of monitoring design with the d
 evelopment of active and passive RFID technology to survey gravel mobility
  and large-scale regional approach to move from opportunistic to targeted 
 actions.\n\nShort Bio :\nHervé Piégay is Research Director at CNRS – N
 ational Centre of Scientific Research\, ENS of Lyon\, France. His research
  interests range from river contemporary changes to process monitoring  a
 nd characterisation of fluvial corridors by ground and airborne imagery. H
 e is involved in integrated sciences for rivers and is strongly interactin
 g with practitioners (Water Agencies\, Regions\, Ministry of Ecology\, ONE
 MA\, Compagnie Nationale du Rhône\, EDF) providing knowledge for river ma
 nagement\, planning and restoration and methodological frameworks and tool
 s using GIS and remote sensing. Since 2010\, he is the research leader of 
 the scientific team working on the Rhône valley\, being in charge of the 
 Rhône Observatory of Human and Environment Interactions.\n
