ABSTRACT

The paper presents a solution for developing the water body in an enclosure arranged
with engineering works from the Danube meadow in Giurgiu county.

The solution is applicable in the conditions of a half captive aquifer taken from the
Danube Specific for this solution is the type of hydric excess with a higher intensity and
duration than on the border zones.

The experimental field has a surface of 4 ha and is located in conditions of alluvial soil
with a clad texture. The arrangement has absorbing pipes placed at an average depth of
1,20 m connected to the collector drain.

The supply was made from a perfectly drilled well of 4 ha with a depth of 25 m and the
final water column of 520 mm. The tests were performed during 3 years in conditions of
drought. At operating in the artesian mode the level of the aquifer reached a distance of
0,48 m from the land. The daily volume discharged was of 302 m3 /day the water having
the salinity class C2 - C3 and the subclass of alcalinity S1. In the conditions of the
phreatic under pressure the distance between the absorbant drains is small below 8 m
leading to a high specific investment.

The method may represent a solution of soil revegetation by increasing the surface of
the water body.

Keywords: drainage arrangement, under pressure phreatic, arrangement solution, revegetation.
