التحليل الهيدرولوج للمياه الجوفية في شرق محافظة واسط باستخدام نظم المعلومات الجغرافية

الملخص EN

The study of the hydrological characteristics of groundwater in the governorate is prepared by showing the concentrations of salinity and the main elements by adopting fifteen water models collected from several sites in the governorate in different periods representing the increase and decrease of water, as the spread of saline and nitrate pollution in the groundwater in the open reservoir as well as the spread of pollution The salinity is only in the water of the confined reservoir, whether in the sediments of the Quaternary age or the reservoir of the Muqdadiya and Bey Hasan formation.

The analysis models were based on the Geological Survey Office in Wasit Governorate to obtain the results of the analysis for the selected samples.

As it was observed the spread of hydrochemical pollution with salinity and the nitrate ion in the surface waters of the Kalal Badra, Tarsakh and Al Shihabi River, as the high concentration of salinity of its water, which is likely to be affected by the geological and agricultural environment within the Iranian and Iraqi lands, as the concentration of nitrate ion in the river water upon entering the Iraqi lands was characterized by an increase and then began to gradually decrease Towards the bottom of the valley.

Agricultural operations and land uses for agricultural purposes And the purposes of grazing, as well as the washing of sediments contaminated with nitrate ion, led to the spread of salt and nitrate pollution within the open reservoir water after feeding it with percolating water with high salt and nitrate concentrations.

Hydrochemical contamination of groundwater was restricted to the reservoir confined to salinity, where the nitrate ion could not move to the confined reservoir layers, the most difficult areas of exposure.
