Indirect Roles of In-stream Sand Mining and In-stream Vegetation in Relation to Coastal Erosion
Guangwei HUANG （The University of Tokyo）
Abstract:
Coastal erosion may result from a number of factors including the disruption of sediment supply from river to coast due to dam development. In Japan, among the top 30 dams in terms of height, 14 were completed before 1970 and 6 before 1980. However, the coastline erosion problem surfaced up in the 1980s. Therefore, there was a time lag between the disruption of sediment supply by dam and beach erosion. The causes of this time lag are poorly understood. This paper, via a case study, is aimed at providing an answer to what could have delayed the response of beach to the effect of dam construction. Moreover, sediment trapping and erosion are discussed in relation to in-channel vegetation development.
