自然再生・利用・防災機能の向上のための都市型干潟・磯場の整備計画

Abstract

A project which contributes to the enhancement of ecosystem restoration, utilization, and disaster prevention function in the urban shore by constructing a wetland was planned. Since the area was restricted spatially, a terrace type sand flats bounded by rocky shore with bulkhead was employed instead of a sloped beach type wetland. It enabled to use adjacent water surface as living port facilities. Furthermore, the terrace type structure was enhancing disaster prevention function of the seawall by a counter-weight effect. For the detail designing, dimension and material of the wetland was determined scientifically sound way based on enrichment of biodiversity. It was also paid attention on implementation of an adaptive management for public participation and utilization. After the completion, the wetland have been in a utilization and monitoring phase for checking detailed topography, sediment quality, and underground water etc. for implementation of the adaptive management.
