INTERDEPENDENTA FACTORILOR CLIMATICI SI HIDROLOGICI ÎN LUNCA DUNARII - SECTORUL DROBETA TURNU SEVERIN - CORABIA/THE INTERDEPENDENCE OF CLIMATIC AND HYDROLOGICAL FACTORS WITHIN THE DANUBE ALLUVIAL PLAIN DROBETA TURNU SEVERIN - CORABIA SECTOR

The paper provides quantified data concerning the relationships between climatic and hydrological factors in the studied floodplain sector. The obtained values show significant rock-end-Iandform-related differences. Rop dependence coefficient values for the level of the Danube/ ground levels have been registered at Crivina (F1) and CaIarasi-DabuIeni (F1) hydrological posts (82.6% and 78.6%, respectively). The dependence coefficients for the climatic factors (precipitation, temperature and evapotranspiration)/ ground water regime show differences from one borehole to the other, in terms of Iandform, soil and the lithological structure of the aquiferous layer. The maximum dependence coefficient value (91.25%) for the evapotranspiration/ground water level relation was found at CaIarasi-DabuIeni point F2 borehole. Low dependence coefficients were yielded by the precipitation/underground level relation (0.02 and 29.15, respectively).
