When the V-shaped river channel is to be simulated, the transparent V-shaped lining 8 is only required to be connected in the U-shaped transparent glass river channel 3 again, and the water outlet baffle 9 is connected to the reservoir 2 again. The water outlet baffle 9 seals up the port of the U-shaped transparent glass river channel 3, water is continuously introduced into the reservoir 2, and the water level of the reservoir 2 rises and overflows the water outlet baffle 9 to enter the transparent V-shaped liner 8. The subsequent simulation process is similar to the U-shaped river channel.
