水底堆積物の堆積深さ測定方法及び装置

Method and device for deposit depth measurement in water bottom sediment

Abstract

【課題】 構造が簡潔で壊れにくい測定装置と、簡便な水底堆積物の堆積深さ測定方法を提供する。 【解決手段】 測定装置(1)は、目盛を有する紐状部材(4)と、その先端に取り付けられた測定部材(5)とを備える。測定部材は、水中に沈み且つ水路の水底堆積物の表面上に接地したときに堆積物中に埋没しない形状である。この測定装置を用いて、水路の壁の上面から堆積物の表面までの深さを測定し、この深さを水路の深さから差し引くことにより堆積物の堆積深さを求めることができる。 【選択図】 図1
<P>PROBLEM TO BE SOLVED: To provide a measuring device which is simple in structure and will not break easily and to provide a simple deposit depth measuring method of water bottom sediment. <P>SOLUTION: A measuring device (1) consists of a string-like member (4) with a scale and a measuring member (5) attached at a tip. The measuring member which sinks in the water and grounds on a surface of the water bottom sediment of a channel, has a shape which will not bury in the sediment. By using this measuring device, the depth from the top surface of wall of the channel to the surface of the sediment is measured, the sediment depth of the sediment can be obtained, by subtracting this depth from the depth of the channel. <P>COPYRIGHT: (C)2007,JPO&INPIT
