A REPORT ON PRESENT SITUATION OF SEA-SAND MINING IN THE WESTERN PART OF JAPAN
Doboku Gakkai Ronbunshu, 1994 西日本では, コンクリート構造物や道路等の細骨材としてそのほとんどを海砂に依存している. 沿岸海域における多量の砂採取は, 海岸侵食や漁場荒廃等の環境問題を引き起こす可能性があることは以前より指摘されている. しかしながら, これまで西日本における海砂採取の状況について総合的に調査・報告された例はほとんどない. 本報告では, 沿岸環境保全と調和した海砂採取はどうあるべきかという考えに立脚し, 西日本各県における海砂採取基準, 採取場所および現在までの採取量について系統的に調査した結果を報告している.

IOP Conference Series: Earth and Environmental Science, 2023 Abstract The beach reclamation project is carried out through a sand mining process in the middle of the sea. This is claimed to cause vulnerability to environmental damage in the form of coastal abrasion, thus giving rise to a resistance movement from the surrounding community. This qualitative study aims to obtain information about the

IOP Conference Series: Earth and Environmental Science, 2020 Abstract Marine sand mining in Pantai Labu in 2008-2009 and 2017-2018 have drawn protests from the local community because they are detrimented. The impact of this marine sand mining results in environmental damage (degradation) of the coast such as abrasion and decreased productivity of marine fisheries due to declining water quality ...

Linear instability mechanisms for sand wave formation [PDF]
, 2000 A height- and flow-dependent model for turbulent viscosity is employed to explain the generation of sand waves in tidal seas. This new model resolves the problem of excitation of very long waves in sand wave formation, because it leads to damping of the ...
