Das Ngrowo-Ngasinan: Pengaruh dan Manfaatnya Terhadap Tinggalan Arkeologi Di Trenggalek

The Ngrowo-Ngasinan watershed is one of the Brantas watersheds covering an area of ​​1,188,800 hectares located in the Trenggalek Regency. The Ngrowo-Ngasinan watershed consists of forests, fields, irrigated rice fields, plantations, and settlements which are flooded every year. Flood conditions that occur have an influence on archaeological remains around the Ngrowo-Ngasinan watershed, namely Brongkah Temple, Semarum Site and Kamulan. Most of the archaeological remains are buried by alluvial deposits due to flooding and the overflow of the Ngrowo – Ngasinan River. The results of research conducted by Balar DIY in 2012-2015 through survey and excavation data collection methods indicate that the Semarun and Kamulan sites were abandoned because they were inundated and drowned due to the overflow (flood) of the Ngrowo and Ngasinan rivers. The purpose of this article is to determine the effect of the existence of the Ngrowo-Ngasinan watershed on the loss or damage of archaeological sites around the Ngrowo-Ngasinan watershed. Morphologically, the archaeological sites in the Ngrowo-Ngasinan watershed have a very ideal position as a place of settlement, because their location is in a basin and sloping area, fertile, and close to water sources. The conclusion should be at the end of the abstract. Avoid the word 'disaster' (adjust title). Conclusion: The selection of residential locations around the Ngrowo-Ngasinan watershed has a very significant impact or great risk for flood disasters because of its location on the banks of the river. Keywords: Ngrowo-Ngasinan Watershed, archaeological remains, flood.
