The long term (Holocene) channel and floodplain dynamics of a low gradient, low energy, fine grained aggradational fluvial system within a formerly glaciated landscape in central Scotland, the Kelvin Valley, are described from a series of sediment stratigraphic transects and 12 14C assays in a headwater reach between Kirkintilloch and Kilsyth. The 14C assays and dated archaeological sites on the floodplain together suggest that the River Kelvin ceased to aggrade more than 2000 years ago, probably much more, so the 4–6 m of channel and floodplain deposits are almost entirely of early to mid-Holocene age. The Kelvin Valley is characterized,despite its low flow characteristics, by a highly variable floodplain architecture, in which some transects suggest long term channel stability and strong partitioning of floodplain sedimentation and others indicate high channel mobility. This variation makes the application of general models of fluvial evolution difficult
A summary of these specialist reports (Parts 1 and 2) was published in 2008 in the monograph on the Holyrood Parliament Site Project: Scotland's Parliament Site and the Canongate: Archaeology and History by the Holyrood Archaeology Project Team, Chapter 3.9 & 3.10 (HAPT 2008). Except for sections 3.9 and 3.10, Chapter 3 in that monograph has been repeated here as Part 3, in order to provide the archaeological context for the artefactual and environmental evidence alongside the specialist reports.
This report describes the results of three archaeological excavations which took place within the medieval burgh of Dumbarton, two by Eric Talbot between 1971 and 1972 on the High Street and at College Street and the third, on the High Street, by SUAT in 1997. Evidence of medieval activity, including metal working, was found on burgage plots in the High Street. A large pottery assemblage provided an important opportunity to investigate medieval trends in a west coast burgh, an area hitherto under-represented in ceramic studies. Glass waste at College Street may have originated from the site of the late 18th/19th-century Dumbarton Glassworks.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
