Abstract:
The draining-drainage systems carried out for eliminating the excessive humidity on agricultural lands were designed
with respect to the exploitation of surfaces on the draining sectors. Since upon the construction and reconstruction of
property rights the orientation of the absorbent drainage lines and drying network was not considered, the plots of land
are either perpendicular on, or parallel to, or even form an acute angle with these absorbent drains and/or drying canals.
The different soil works performed on each individual plot has led, in time, to the formation of ridged strips of variable
widths, level differences and transverse slopes, depending on the width of the plots, on the manner in which they are
used and on the machinery employed for the agricultural works conducted. The land shaping in ridge straps and their
different orientation of to the drain lines and the channel network leads to a non uniform elimination of the water excess
on the drained land. On the arable drained land surfaces with individual parcels orientated along the level curves, the
land shaping in ridge straps produced water stagnation on drains and the accentuation of excessive humidity especially
in spring and raining seasons which lead to the gradual passing of the parcel to a lower category of use, that is
grasslands. Non-ridged plots enjoy better excessive water removal, which enables farmers to perform adequate and
timely spring works and thus have better agricultural productions. The draining-drainage systems carried out for
eliminating the excessive humidity on agricultural lands were designed with respect to the exploitation of surfaces on
the draining sectors.
