Özet
In order to characterize, classify and evaluate the suitability of groundwaters for irrigation in Zilan and Bendimahi basins hydrochemical assessment was conducted. In this paper, hydrographical methods were used to characterize water quality of groundwaters in Zilan and Bendimahi basins. Water chemical composition was studied by collecting 36 groundwater samples (6 samples in Zilan basin and 30 samples in Bendimahi basin). In content of this paper, % Na, sodium adsorbsion ratio (SAR), residual sodium carbonate (RSC), permeable index (PI), Kelly ratio, magnesium hazard (MH) and boron concentration were investigated. The quality assessment of Zilan basin for irrigation purposes showed that ‘’Very well – Well’’ usable waters in terms of sodium percentage (% Na), they are in ‘’low sodium hazard and low salinity hazard’’ region in terms of sodium adsorbsion ratio (SAR) and in C1S1 water class. Waters in Zilan basin have under the 2.5 meq/l in terms of carbonate and bicarbonate hazard RSC (residual sodium carbonate) and it shows that they are suitable for irrigation. 66 percent of waters in Zilan basin is in Class I and it is suitable for irrigation according to permeable index (PI), usable for irrigation according to Kelly ratio and it is suitable in terms of magnesium hazard (MH) because of MH values are lower than 50 for a lot of samples. The quality assessment of Bendimahi basin for irrigation purposes showed that waters are ‘’Very well – Well’’ and ‘’Well-Usable’’ water class in terms of sodium percentage (% Na), they are in ‘’low sodium hazard and low salinity hazard’’ region in terms of sodium adsorbsion ratio (SAR) and in C1S1 water class. Much water in Bendimahi basin have under the 2.5 meq/l in terms of carbonate and bicarbonate hazard RSC (residual sodium carbonate) and it shows that they are suitable for irrigation. 90 percent of waters in Bendimahi basin is in Class I and it is suitable for irrigation according to permeable index (PI), usable for irrigation according to Kelly ratio and it is suitable in terms of magnesium hazard (MH) because of MH values are lower than 50 for a lot of samples (percent of 70). Various irrigation indices show good to permissible use of groundwater in agricultural activities.
