Abstract

PURPOSE:To facilitate the measurement of a scoured depth by detecting non continuous parts of the ground measuring the temperature distribution with thermosensitive sensors arranged at a specified space from the ground under the water surface to the surface. CONSTITUTION:A long pipe 6 housing thermosensitive sensors arranged at an equispace is placed on the upstream side of a bridge pier 10 in such a manner that the tip 6a thereof is buried under the ground while the upper end 6b thereof is fixed on the bridge pier above the water surface A. The temperature distribution is measured with a temperature sensor and the surface C of the bottom is detected from non-continuous parts of the ground. During a flood, the water surface moves to B while the ground surface under the water surface is scoured down to D. The position C can be detected in the same way with the position C thereby facilitates the measurement of scoured depth lx.
