Abstract. The studied territory is at the interference of the low plain (toward Jebel, Ciacova, Ghilad, and Banloc) with the high plain (toward Lieblieng, Folea, and Gătaia). Due to this interference area, the relief is fragmented. It has slopes of 1-5% from east to west, south-west. Altitude ranges between 92 m (south-western extremity) and 108 m (eastern extremity). (4) The low plain is a divagation plain made up of a succession of small hills and fluvial-lacustrine depression areas. This plain is mainly a recent plain, though it appears to have frequent bumps represented mainly by deserted meanders of old watercourses, micro-depressions, and small hills. This is due to the uneven deposit of alluvial material and to subsequent changes.(1) The small hills, whose texture is coarser than that of the surrounding forms of relief, shows manmade influences. In both plain and small hill areas, there are depression-like forms (small depressions, micro-depressions, inter-hill areas, wide depression areas, deserted meanders) where water stagnates for long periods, particularly during abundant rains and snow melting. (6) As for the depth of ground waters in the low plain, it ranges between 0.5 m (in depression areas) and 3-4 m in hill areas). The passage to high plain is after are rather sinuous route marked by more or less remarkable slopes ranging within 5-15%. The high plain area is located in western Voiteni and is a relatively even area interrupted here and there by narrow valleys. On this relatively even valley, there are small depressions with no natural drainage where water from rainfall stagnates during rainy periods (also because of the predominant loamy-clayey soil texture). Therefore, in both low plain and high plain areas we need to develop and improve the existing drainage system. (3) To carry out the study, we used both data from our own observations in the field and data from previous research. (5, 9)
