Experimental Scene
The scope of the model reproduction was the diversion channel and several kilometers of the river channel upstream and downstream. The diversion channel and river channel based on the basic design were reproduced in a 1/70 scale model.
The design flood discharge and the maximum historical discharge were passed through the river to examine the effect of lowering the water level in the diversion channel and the shape of the diversion facility from the river channel to the diversion channel.
