This enables the sediment with the large particle diameter to be separated from the sediment on the bottom 7 and used as a construction material etc., and enables the arbitrary fine-grained fraction to be separated and placed as a feed material for the river in the river so as to recover an eroded river bed in the downstream area of the dam and the coast near the river mouth.例文帳に追加

ダム湖底７の土砂から粒径の大きい土砂を分離して建設資材等に使用することができるとともに、任意の粒径の細粒分を分離して河川供給材として河川内に置土することで、ダム下流の侵食された河床や河口付近の海岸を回復させることができる。 - 特許庁

To provide an observation ship for measuring sound capable of carrying out operations such as the measurement of depth of shoals in rivers, lakes, nearshore waters, dams, etc., the acquisition of the three-dimensional information of river bed shapes and underwater structures, and the acquisition of river bed sediment information, and to provide a sound measuring system utilizing this observation ship.例文帳に追加

河川、湖沼、沿岸海洋、ダム等における浅瀬の測深、河床地形や水中構造物の三次元情報の取得や、河床底質情報の取得等を行うことのできる音響計測用観測船及びこの観測船を利用した音響計測システムを提供する。 - 特許庁

To provide a method for improving the roughness of a revetment structure, which can prevent the cracking of a river bed, the accumulation of sediment in a low-water channel, and a shift to a forest.例文帳に追加

河床の深割れ防止、低水路内の土砂堆積や樹林化の防止を実施することができる、護岸構造物の粗度の改善方法を提供する。 - 特許庁
