Yonghui Liang,Xuefeng Zhou,Hao Guonerally, water quality is evaluated using several indicators, including chemical oxygen demand (COD), biochemical oxygen demand (BOD), and dissolved oxygen concentration (DO). In the present investigation, two artificial intelligence techniques, namely, adaptive neuro-fuzzy inference system (ANFIS)

Hua Chen,Zhe Zhao,Zuhao Changum. The concentrations observed are generated by the phenomenon of dissolution of gypsiferous formations. The graphics realized shows hilt concentrations in the first aquifer, but in the deep, the concentrations become low. This repartition explains the retention of elements by the soil.
