This paper descries predictions of saline water current advancing into brackish lakes in series using a 3D numerical model. The numerical model was tuned through the comparison with results of the laboratory tests performed using a water tank which was made of acrylic acid resin composed of two rectangular model lakes connected with a narrow channel. The present numerical model could capture well the fundamental aspect of the flow behavior of the density current when we used a proper tuned vertical eddy viscosity coefficient. In order to control the behavior of advancing saline water, we tried to use a 1/4-sphere type brick proposed by Komatsu et al. The numerical results showed that the bricks are effective to decelerate the density front and decrease the density of salt near the bottom of the lake.
