Observations glaciologiques et hydrométéorologiques en zone de montagne / Hingray, Benoît in La Houille blanche, N° 2 (Avril 2012) 

Public ISBD [article]  in La Houille blanche > N° 2 (Avril 2012) . - pp. 5-11 Titre : Observations glaciologiques et hydrométéorologiques en zone de montagne : Quelques problématiques et perspectives actuelles Type de document : texte imprimé Auteurs : Hingray, Benoît, Auteur ; Jean-Pierre Dedieu, Auteur ; Thierry Lebel, Auteur Année de publication : 2012 Article en page(s) : pp. 5-11 Note générale : Hydraulique Langues : Français (fre) Mots-clés : Observation  hydrométéorologique  Montagne  Surveillance  environnementale  Changement  global  Processus  Modélisation  Prévision  Risques  hydrologiques  Ressources  en  eau  Changement  d’échelle  Régionalisation Résumé : Hydrometeorological observations are the basic material for a number of scientific and operational issues. They are required for studies aiming at understanding and/or modeling climate-environment-society interactions along with their spatial and temporal variations. They constitute also the basic information for estimating hydrological resources and risks, for their real time management or for prospective studies that aim to foresee adaptations strategies required by societies to face changes in resource and risks induced by ongoing global change. In mountainous areas, such observations are even more important as hydrometeorological events are more pronounced and variable than anywhere else. Here, the interest of hydrometeorological observations systems such as GlacioClim in these regions is highlighted for various key hydrological issues, taken from the operational, research or environmental monitoring domains. Several observatories or measurement networks developed to meet corresponding objectives are presented. Limits of observations, associated to the measurement itself, to their spatial representativeness, to their temporal coverage and permanence are discussed. Some perspectives for improving current observations systems are finally suggested.
