| Research Abstract |
The purpose of this study has been to make the regional history evidence with the sites of internal water level and with the environment of historical images on ECHIGO-Plain. Specially, we should advance to discovering of NUTARI-palisade with a new understanding based on analysis of manuscripts, old maps and archeological remains, and with a boring survey & excavation.
(1)The conjectured location of the NUTARI-palisade has been OSE that is based on Jokyo map of the Nuttari section of Niigata City, and we conducted a boring survey. We verified an accumulation of a flow of volcanic ash and a swamp from about 5000 years ago at a depth of about 18 meters beneath the railroad tracks and confirmed the need to fundamentally re-write the conclusion heretofore, derived from land surface observations, that formation of the new sand dune III presumed to have been formed in the Tomb Age, actually dates from before the middle Jomon era.
(2)At a depth of about five meters we discovered an old stratum
… More
of topsoil above which were accumulated remains of vegetation with a carbon 14 data of about 1180 plus-or-minus 30 years. We employed a geoslicer commonly used in probing earthquakes to examine in stead of excavation. We were able to determine that this area was old wet rice paddy. And we have thought that there is remained in this soil of the sites of NUTARI-palisade and KANBARA-harbor.
(3)As for geological features, we advanced general understanding of the action of sand barrier systems and delta creation that formed the Echigo Plain and also geotechtonic structures.
We have advanced a new understanding the intimate link created by the internal water level between the NUTARI and IWAFUNE palings. For the medieval era, we have identified the autonomous management of the activity of the GEJYO-boats that plied both the Age and Shinano rivers, we have understood natural development of the regional characteristics of the area, and we have implemented supplementary investigations.
(4)These research results were presented at an international/regional interdisciplinary symposium in an exchange with Professor of Korea, USA, UK, these scholars uniformly called for sharing of our studies with scholars throughout the world for the purpose of promoting regional and comparative study. And we held a public symposium directed at general audience. Less
