Abstract

The water is regarded as the life  blood for all living beings and an important source as stated in the name of God the Most Gracious the Most Merciful. "We made form water every living thing", as it enters the formations of environments, and is the first necessary needs of human.

    There is no doubt that the most important forms of water resources, which is acquire it,s great importance in arid and semi-arid lands. and investing of this water of course requires knowledge of their quantities and their physical and chemical properties, which are directly reflected on their quality and uses.

     The importance of the study is that groundwater wells are one of the most available natural resources in the eastern part of Maysan province, which will contribute extensively to various human activities.

Groundwater wells are located on the border between Iraq and Iran. Many natural factors contributed to the availability of these wells in these areas, including geological construction, terrain and slopes, as well as climate and soil conditions. These factors played an important role in the variation of the hydrological characteristics of these wells, on the other hand.

The study area is located east of the Tigris River from the province of Maysan, which is located in southeastern Iraq, an area of about (4423.48) km 2. As for its astronomical position, it lies between two latitudes (49 14 31, 51 49 32) north and the arcs length (32 28 46, 42 51 47) to the east.

     The study revealed that the geographical information systems (GIS) have the ability to identify and represent the hydrological characteristics and the quality of the cartographic representation. The nature of the geographical distribution of the phenomenon is also of random type, as it is clear that it does not take a systematic trend in its distribution.
