The bubble plume images are grabbed by CCD(Charge-Coupled Detector).The digital images process technique was employed to analyze the grabbed images of the bubble plume. Experimental results show that the width of two-dimensional bubble plume increases as increasing the source strength. When the ambient water density becomes larger, the two-dimensional bubble plume also becomes wider. The difference of the two layer ambient water density becomes larger, the width of bubble plume intrusion increases accordingly.
