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.
The application of the Law no. 18/1991 on the drained lands, the
corresponding extreme division of arable surface and the individual
execution of soil works lead, in time, to a shaping in ridge straps with widths,
level differences and variable cross slopes according to the width of the
parcels, their use and the machinery employed in carrying out agricultural
works. When people were given land in property, the orientation of
absorbing drain lines and the draining network were not taken into account,
the land parcels are perpendicular, in a sharp angle or parallel to the
absorbing drains and/or the draining channels.
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.
The elimination of the humidity excess on these individual parcels may
be achieved through exploiting leveling in view of voiding drains and micro
caves and combining ridges between furrow with dead furrow.
