ΠΡΟΔΕΛΤΑΙΚΕΣ ΑΠΟΘΕΣΕΙΣ. ΣΕΙΣΜΙΚΗ ΣΤΡΩΜΑΤΟΓΡΑΦΙΑ-ΙΖΗΜΑΤΟΛΟΓΙΑ-ΕΥΣΤΑΘΕΙΑ ΠΡΑΝΩΝ

THIS THESIS IS CONCERNED WITH THE ANALYSIS OF CONTINUOUS SEISMIC PROFILES (3.5 KHZ), THE STUDY OF GEOTECHNICAL PROPERTIES AND THE SLOPE STABILITY IN THE PRODELTA DEPOSITS OF PIROS, EVINOS, MORNOS AND PINIOS RIVERS. SEISMIC INDUCED MASS MOVEMENTS AND SEDIMENT FLOWS WERE CONCLUDED FROM 3.5 KHZ PROFILES SUCH AS: 1) CREEP IN EVINOS AND THE WESTERN SECTION OF MORNOS PRODELTA. 2) DEBRIS AND TRUBIDITY FLOWS, AS WELL AS INTENSE SLUMPING PHENOMENA IN THE EASTERN SECTION OF MORNOS PRODELTA. 3) POSSIBLE DEBRIS FLOWS OF RELATIVELY COARSE CLASTIC MATERIAL IN THE PRODELTA OF NORTH PELOPONNISOS SEASONAL RIVERS. THE GEOTECHNICAL PROPERTIES DISPLAYED HIGH VERTICAL AND SPATIAL DIVERSITY WITHIN THE PRODELTA SEQUENCES. THIS IS DUE TO FLUCTUATIONS OF NEAR BOTTOM HYDRODYNAMIC CONDITIONS, VARIATION OF DEPOSITIONAL MECHANISMS (ESPECIALLY THE SEDIMENTATION RATES), TO VARIOUS MASS MOVEMENTS AND FINALLY TO POSSIBLE DIFFERENCES IN CLAY MINERAL COMPOSITION. THE FACTOR OF SAFETY (F) OF PIROS AND PINIOS PRODELTA SLOPES WAS FOUND TO BE FAIRLY HIGH (STABLE CONDITIONS) WHILE LOW VALUES WERE ESTIMATED FOR THE PRODELTA SLOPES OF EVINOS AND MORNOS. IN THIS WAY THE PRODELTA SEQUENCES OF THE RIVERS EVINOSAND MORNOS DISPLAYED LIMITED EQUILIBRIUM ACCORDING TO THE INFINITE SLOPE STABILITY ANALYSIS UNDER UNDRAINED CONDITIONS.
