This paper presents the results of the water physical properties of eugley in the area of the central current of
Danube River, the part of the alluvial plain which is protected from flooding by an embankment. The aim of the
research during vegetative period was to present the basic physical properties of this soil in the protected part of
the alluvial plains, the depth of underground water, and distribution of the immediate moisture. It was determined
that this land had a high total clay content, ranging from 60.02 to 70.26% on the average. According to
granulometric composition, the textural classes ranged from loamy sand, sandy-clay loam, loam to clay loam.
Specific mass values ranged from 2.65 to 2.84 g/cm3, volume mass from 0.96 to 1:54 g/cm3, and the total porosity
of this soil ranged from 43.22 to 64.31%. Air capacity of this soil ranged from 3.1 to 34.7% vol, and plant available
water ranged from 7.96 to 28.80% vol. During the measurement of groundwater levels in 2006 when Danube water
level was high, a high correlation coefficient was determined (r = 0.72 to 0.96) between water level and underground
water oscillation, in 2007 correlation was low (r = 0.07 to 0.25).
