Résumé :
|
In symposium 5 (14 communications),the effect of relief on several geophysical methods was presented.Symposium 6 (18 communications) presented the synthesis of the obtained with a great deal of mathematical models in many recent applications.The efforts of the nuclear industry to prospect possible sites for repositories brought particulary interesting developments in large-scale modelling.The role of discontinuities in sach models has been described in several papers.The representativity of imput data is another important theme in the simulations of large regions in complex stratigraphical and tectonic structures.Symposium 7 (66 communications) received many papers on the determination of the origin of groundwater by the study of the hydraulic and mainly geochemical response of flow systems.Recent developments in the analysis of the compounds present in the water brought interesting prospects in the direction of natural tracers.This constitutes a very useful tool the validation of mathematical models.In the last topic,the effect of long-term hydrological variations on deep flow systems added interest to the subject of his symposium.Symposium 8 (62 communications) grouped many pratical applications of all of these methods.First of all,solutions were presented to resolve the staggering between supply and demand during the low flow season in the mountains.Then,specific rules for the transposition of classical protection zones were studied in rugged relief regions with a special characterization of risks specific to his topic.Particularly,systems of sewage treatment at high altitude were compared in some alpine countries.Finally,the integration of underground works and waste disposal in mountainous environments was treated according to the most recent research on this subjet.The session on the effect of underground works on groundwater resources was also attented by scientists of the Swiss national committee of the IAH as well as by the members of the Swiss group of engineering geologists invited to this special meeting.
