Abstract This study was conducted for the purpose of estimating the soil and water quality of the Gharraf River Basin in the north of Dhi Qar Governorate using geomatics techniques represented by geographic information systems (GIS), remote sensing (RS) and positioning systems (GNSS). Which is about (90 km) from the city center. The chemical analyzes of the water samples showed that the degree of interaction was between (7.84-7.7) and the electrical conductivity (dS.m¯1.1-1.05), and the total dissolved substances were between (1106-1051ppm), and the mathematical statistical relationships were weakly correlated with the ratios of the visible space bands. pH, electrical conductivity and total dissolved materials. Calcium ratios in the study area ranged between (ppm 47.4-107) and there was a significant correlation with the range (B/R + B) with a value of (R2 = 0.51), and the results showed the ratios of magnesium in the study area between (ppm 9.67 - 26.61.) Between it and the band ratio (B/R + B)), a correlation relationship with a value of (R2=0.525), potassium recorded an average between (3.1-ppm 5.5), and there was a significant correlation between it and the band ratio (B/R +R) and it reached (R2=0.665). ), found a statistical relationship between sodium and the ratio of the band (B/R + R)) and a significant correlation was recorded with a value of (R2 = 0.527). - 102.52) And there was a correlation between the presence of chloride and the ratio of the range (B/NIR + G) as it was recorded (R2 = 0.593), the bicarbonate recorded ratios between (ppm 1.8-2.7), and there was a statistical relationship between the bicarbonate and the ratio of the range (C / R). ) amounted to (R2 = 0.573), nitrate values were recorded in the study area between (4 - 3.45 ppm) and there was a significant correlation between them and the range (B5) as it reached (R2 = 0.581), sulfate values were recorded between (207.25 - 277.5 ppm) and through Statistical analysis found that there is a correlation between The presence of sulfate with the ratio (C + B + G + R + NIR) which amounted to (R2 = 0.596), the sodium adsorption ratio (SAR) was calculated, as its values ranged between (3.192 - 0.147) and most of the statistical relationships were weakly related to the spatial ratios and were gradually The hardness values in the study area are between (99.7 - 198.1)(

The main intent of this study was to investigate the condition of groundwater quality for irrigation purposes in and around the main Gadilam river basin, the east coast of southern India. A total of fifty groundwater samples were collected and analyzed for various parameters such as electrical conductivity (EC), pH, TDS, major cations (Ca2+, Mg2+, Na+, and K+) and anions (SO42-, Cl-, HCO3-, and NO3-). Irrigation water quality parameters like the sodium absorption ratio (SAR), residual sodium carbonate (RSC), percentage sodium (%Na), magnesium hazard (MH), permeability index (PI), and Kelly ratio (KR) were computed to assess the irrigation water quality of groundwater. Furthermore, graphical representation diagrams such as USSL, Wilcox, and Doneen have been prepared for irrigation water quality. From the computation of SAR, Na%, RSC, PI, and KR values, it was found that 100% of groundwater samples were found to be suitable for irrigation purposes. Besides, USSL and Doneen diagrams show that the samples are safe for irrigation usage. The Wilcox diagram in the classification of electrical conductivity reveals that most samples fall into the good to permissible class (78%), in doubtful to unsuitable class (20%), and 2% of samples are unsuitable. Magnesium hazards of 82% of the groundwater samples are suitable for irrigation, while the remaining 18% of the samples exceeded the limit and found to be unsuitable for irrigation purposes. The study concludes that higher percentages of groundwater samples were suitable for irrigation purposes in the study area, and the concentration of magnesium influenced groundwater at a few locations.

Abstract Overview of assessment in geographical areas (GIS) and model reviews, positioning (GNSS), positioning, this study was conducted for the purpose of estimating the soil quality of the Gharat River Basin in the north of Dhi Qar Governorate using geomatics techniques represented by geographic information systems (GIS), remote sensing (RS) and positioning systems (GNSS). Which is about (90 km) from the city center. In nature soils and the correlation (B / C) reached (R2 = 0.907) for sand, while the clay was correlation with the range (B / R) and it was (R2 = 0.763) in While the correlation between the silt and the band (B/R) was recorded (R2 = 0.730), the ph record (7.8-8.42) as it was classified as a neutral slant to the basal and it was clear from the statistical analysis that there is a relationship with the range (C / B) as it reached (R2 = 0.583). The results showed a decrease in the values of soil samples between (0.2 - 1.7%) and the results of the analysis. 0.114% -0.197%) and the results of the statistical analysis showed the correlation of the range (C/NIR) and gypsum with a correlation value of (R2 = 0.686) in the proportion of lime ranged between (64.5% -21.5%) and the statistical analysis showed a correlation between calcium carbonate and the relativity of the range (C / NIR) as recorded (R2 = 0.513), the results of the analysis of samples from the study samples ranged between (26.86-395.55), and through the statistical analysis it was found that there is a relationship between the rate of sodium adsorption and the ratio of the bandwidth of the satellite visual correlation amounted to (R2 = 0.736), and it ranged The electrical conductivity values for the soils of the study area (5.79 -44.2 dS.m¯1) and it was a correlation (G / R) and the correlation value was (R2 = 0.602), the calcium values in the area. The study ranged between (400-1944 ppm) and the correlation numbering (R2 = 0.640) and the rates of magnesium in the study table ranged, the correlation coefficient (R2 = 0.602), the sodium record between (50-1307 ppm) and the correlation range was (C / NIR) ) Correlation coefficient reached (R2 = 0.920), calcium carbonate ratios were found in the study stations (64.5% -21.5%) and its ratio reached with the range (C / NIR) as the proportion of gypsum in the region was calculated. The correlation coefficient of gypsum and range (C / NIR) was calculated) where it reached (R2 = 0.686), the sodium adsorption ratio (SAR) was calculated and meals were between (26.86-395.5) and there was an association with the range (B / R + NIR) as it was recorded (R2 = 0.737)
