Question

The distorted models, used in the hydraulic studies, are those which

• A. have exaggeration of the vertical scale and horizontal scale
• B. are not geometrically similar to the prototypes
• C. have same vertical and horizontal scale as that of the prototypes
• D. have same Froude number as that for the prototypes

Answer 1

The correct option is B are not geometrically similar to the prototypes

Distorted model can have vertical scale exaggeration or slope exaggeration. Therefore they are not geometrically similar. It may have either geometrical distortion, or material distortion or distortion of hydraulic quantities or a combination of these.
