A large network of canals was established during the last decades for delivering irrigation water in the SCARP-VI Project area. The canal network and irrigated areas became a source of recharge, causing a continuous rise in the watertable. To lower the watertable in the area, 632 tubewells were installed during 1976-80. Since the project began, these wells have been continuously monitored. From this, maps and reports regarding water quality and water level have been prepared. According to the water quality report (SMO,1990) some wells were converted from fresh to saline. To find out the extent of tubewell water quality deterioration, 44 piezometers were installed on seven pumping wells to collect and analyze water quality and piezometric head data. This analysis shows a seasonal variation in water quality. This paper explores possible reasons for this seasonal variation in water quality. For this purpose, different numerical models such as MOC, MODFLOW and RADFLOW were used to study the overall regional flow behavior in the area. The results indicate the water quality variation of the wells may be due to the movement of saline interface in the immediate vicinity of the wells, depending on the recharge and pumping pattern.
