valuation of Groundwater Characteristics in the Hatra District

Abstract

The characteristics and qualities of groundwater Different In her lineageFrom one area to another According to to Rainfall amount and intensity Firstly And nature Topography, rock composition and vegetation secondly In general, the percentage of water seeping into the ground ranges between (15- 20%) of the amount of infiltrated rain water where Groundwater plays a role indifference Its types play a prominent role in the ranges .dry little Rain, as its presence contributes to increasing agricultural areas.and human settlement

Our research aims To know the most important Features The chemistry of groundwater in Hatra district, Nineveh Governorate, through studying the depths of wells and groundwater levels in the manta Accuse me Productivity (water discharge) as an indicator necessary to express The extent of the abundance of underground reservoirs

How it works: Knowing the most important chemical properties of groundwaterThe researchers resorted to selecting (60) locations distributed in a scientifically studied manner covering all parts of the research area, where the depths of the wells and their production capacity were measured as important spatial characteristics that give a comprehensive picture of the nature of those wells and the extent of their benefit in establishing various projects, in addition to relying on the results of analyzing the samples taken directly from the wells by the researchers, and their number reached (20) wells if they were analyzed in the General Directorate of Agriculture in Anbar Governorate, and the other section was taken from the Ministry of Water Resources, the General Authority for Groundwater Investment, the Private Information Bank Department in Nineveh Governorate andWhich mainly represents its content of total dissolved salts (TDS) and the hydrogen ion (PH) and electrical conductivity (EC) and nitrates (NO3) and sulfatesSO4) and chloride (CL) and the sodium adsorption rate (SAR)To know the features and characteristics Its geographical distribution varies between parts of the research area.

The most important results of the research: Variation of well depths and groundwater levels between parts of the research area ,and The diversity of its sources of nutrition and the difference in the abundance of water within the groundwater reservoirs, And The groundwater of the studied wells was classified in terms of the value of (PH) It is divided into two categories, which range from neutral to weakly alkaline water.As it appeared The research showed that the rates of total dissolved salts varied between the studied wells due to their variation in proximity to groundwater sources and variation in water velocity within cracks and pores in the rock.
