Abstract This study aims to evaluate the water quality and reuse potential of groundwater combined with a saline solution for irrigation. The brine dilution process was done by adding determining total dissolved salts (TDS) value according irrigation criteria then calculating amount be added using law concentrations obtain mixture, as TDS decreased from 4922 3810 mg/l 2587 2200 mg/l, respective...

In the present paper, some finite element softwares about interaction of dam and reservoir during earthquake in time domain are discussed. Impedance option is used as boundary condition of absorbent of reservoir and wave. For each software, time history analysis of pressure and displacement are done and finally suitable elements for dam structure and reservoir fluid are introduced comparing the...
