1. A debris-flow simulation apparatus, comprising:
a flume comprising a plurality of flume bodies connected to each other in a longitudinal direction, wherein heights of the flume bodies are able to be adjusted so that angles of inclination of the flume bodies are variable, wherein length of the flume is variable, wherein the flume bodies of the flume comprise:
an upper flume body, an angle of inclination and a width of which are variable;a medial flume body connected to the upper flume body, the medial flume body being variable in an angle of inclination, a width and a length; anda lower flume body connected to the medial flume body, the lower flume body being variable in a width and a length, wherein each of the upper flume body, the medial flume body and the lower flume body comprises:
a first side part comprising a first bottom surface, and a first sidewall vertically connected to the first bottom surface; anda second side part comprising a second bottom surface, and a second sidewall vertically connected to the second bottom surface,wherein when the second bottom surface is put into contact with the first sidewall and is placed on the first bottom surface, the width of the flume body is a minimum width,as the second bottom surface moves on the first bottom surface in a direction away from the first sidewall, the width of the flume body increases, andwhen the second bottom surface is put into contact with the first bottom surface and is level with the first bottom surface, the width of the flume body is a maximum width. |
