Les rseaux de drainage glaciaires et les milieux karstiques: analogies morphologiques et modlisation hydrologique, 2008, Jobard S. , Dzikowski M.
Glacial drainage network and karst environments: morphological comparisons and hydrological modelling. Comparisons between glacial and karst environments are used to propose a methodological transfer in the treatment of hydrological data. The technique employed is based on an analysis of recession curves, where a parameter characterizing the degree of development of the drainage system network is varied. This method has been applied to data from continuous hydro-meteorological monitoring of Baounet glacier (Savoie, France) since 2002. The results show an important increase of the glacial drainage network structure during the ablation season, thereby transferring more and more quickly melt water from the surface of the glacier to the proglacial river. Interannual evolution indicates modulations which correspond to an impact of climate forcing on the glacier.

Interactions hydrodynamiques surface/souterrain en milieu karstique [Surface water/Groundwater hydrodynamic interactions in karst watersheds], PhD Thesis, 2008, Baillycomte, Vincent

Ce travail de these s’inscrit dans la problematique generale de la caracterisation de l’alea inondation. Plus precisement, cette etude cherche a caracteriser l’influence des eaux souterraines sur la genese et la propagation des crues en surface dans les cas d’un bassin versant a forte composante karstique. Le site experimental du bassin versant du Coulazou, riviere temporaire qui traverse le massif karstique du Causse d’Aumelas a l’Ouest de Montpellier a ete retenu pour etudier de maniere approfondie les interactions entre les ecoulements de surface et les ecoulements souterrains en situation de crue.

L’etude hydrodynamique de ce systeme karst/riviere s’appuie sur un dispositif experimental adapte a l’observation des phenomenes hydrologiques (pluie, ruissellement) et hydrogeologiques (piezometrie en forage et dans les drains karstiques, suivi hydrodynamique des exutoires du systeme) tres rapides et tres intenses. La dynamique de ces ecoulements est liee au contexte climatique Mediterraneen mais aussi aux structures de drainage en surface et en souterrain qui permettent un transfert et un transit tres rapide des eaux au sein du systeme karst/riviere.

Une description hydrodynamique classique est completee par une approche fonctionnelle des echanges karst/riviere dans le but de mieux comprendre le fonctionnement hydrodynamique d’un tel systeme et de mettre en avant des indicateurs utilisables dans une demarche de modelisation des echanges surface/souterrain. Un premier modele est presente dans la derniere partie de ce document.

**********

This work aims at assessing the flooding hazard. More precisely, the study focuses on the influence of groundwater on the genesis and propagation of surface flows in the case of a highly karstified watershed. The experimental site of the Coulazou River, a temporary River which crosses the karstified formation of the Causse d’Aumelas (western Montpellier) has been selected to study hydrodynamic interactions between surface flows and groundwater flows during flood.

The hydrodynamic study of this karst/River system is based on a suitable experimental monitoring of both fast and intense hydrological (rain, runoff) and hydrogeological (water level in wells and karst drains, discharge measurements at the main outlets of the system) phenomenon. The specific hydrological response of this watershed is due to the Mediterranean climate but also to surface and underground drainage structures which allow very fast water flows within the karst/river system.

A common hydrodynamic description is followed by a functional approach of karst/river exchanges in order (i) to better understand the hydrodynamic behaviour of such a system and (ii) to highlight some indicators that can be used in a modelling approach. A first conceptual model of surface water/groundwater exchanges in karst terranes is presented in the latter part of the manuscript.
 


CROSS ANALYSIS DISCHARGES / SCALLOPS OF VOGUË MILL (ARDÈCHE RIVER), 2012, Cailhol, Didier

Very often, cave walls present forms that have their origin by turbulent flow of water: the scallops. They were object of many studies (in situ observations, analogous modelisation in rocks with high solubility, numerical modelisation...). Here we use an abandoned site (Voguë mill, left bank of Ardèche river), where stacked scallops were studied in detail. Formed during 432 years on a wall built with local limestone, we see three length classes that can be linked to three hydrogeologic situations. The discharge calculated on the base of the length and the form of the scallops was compared to a reference discharge of the Water Agency Rhône Méditerranée Corse. The comparisons show that the difference between field observation and haydrological data is not larger than 20 %. Thus the simple method of scallop studies is validated and shows that it is well adapted for calculating paleodischarges
