HYDROGEOLOGY

HYDROGEOLOGIE

WATER CAUSES A NUMBER OF PROBLEMS IN CIVIL ENGINEERING IN EARTHWORKS AND AS REGARDS STABILITY. STUDIES WERE CARRIED OUT FROM 1973 TO 1975 ON AN EXPERIMENTAL SITE IN NANCY, AND NUMEROUS RESULTS WERE COLLECTED. THE AIM OF THIS RESEARCH IS TO INVESTIGATE: TIME-RELATED VARIATIONS IN MOISTURE CONTENT IN SOILS; FLOWS OF WATER IN HETEROGENEOUS ZONES (ROCK SLIDES, WEATHERING OF MARL) - MEASUREMENTS STARTED IN THIS FIELD WILL BE CONTINUED AND SUMMARIZED; DRAINAGE OF SILT; SEALING OF STORAGE DAMS. FURTHERMORE, GEOPHYSICAL TESTS WILL BE CONDUCTED TO LOCALIZE PREFERENTIAL FLOW ZONES.
