The region of Southeast Srem is rich in ground waters, which is of great significance to agricultural production. The objective of this paper was to designate the zones of different groundwater types from the aspect of recharge, based on the analysis of groundwater regimes in the study area. A very complex groundwater regime in Southeast Srem, which depends on a great number of natural and some anthropogenic factors, makes it difficult to designate clearly the zones of the three main types of groundwater regime.

The area of Southeast Srem is rich in groundwater. Water regime of the first aquifer has a great significance from the standpoint of agricultural production. 32 piezometers were singled out and groundwater depth was measured aiming at the analysis of some groundwater characteristics. In the area of Southeast Srem, groundwater level fluctuates very widely, depending on the distance from water courses. Mean value of groundwater fluctuation in Southeast Srem amounts to 3.49m. In this area, groundwater moves in Southeast direction, i.e.

Drainage system Galovica is situated in southeast Srem. It occupies the area of about 100,000 ha, it has a dense channel network of 30-40 m/ha, 2,575 constructed facilities and 11 pump stations. The main channel - Galovica is 40 km long and it is one of the basic receiving channels of the surplus internal waters from the area of southeast Srem.

The aim of this paper is a case study of a melioration region, which will show the state of the channel network, as well as the scope of the implemented maintenance measures, which resulted in the reduced functionality of the drainage system. Melioration channels are in most cases in the function of drainage, and a minor number has a double function (drainage and irrigation). The dense network of channels, erected throughout the catchment area, is capable of receiving all the design surplus water.
