Overview

The Trent Valley Palaeochannels Database comprises a GIS archive of air-visible palaeochannel features within the floodplain and gravel terraces of the River Trent, and the lower reaches of its major tributaries, compiled by Trent Valley GeoArchaeology (www.tvg.org.uk) during 2003.

The aim of the palaeochannel survey and GIS archive was to assemble a body of data in a form suitable for cultural heritage management through local HERs. Two epochs of aerial photographs were digitised and geo-referenced, and surface-visible palaeochannels plotted within ArcView GIS. Historic mapping and parish boundary data were used as secondary data sources. Text data was appended to the spatial GIS, recording the physical form of the palaeochannel, National Grid reference, photographic source(s) and map source(s).

Further information, including a guide to the archive, is available at http://www.tvg.bham.ac.uk/palaeochannels.pdf.

The Database

The palaeochannel data is available in ArcView shapefile form, and can be downloaded here.

855 likely palaeochannel/ridge and swale features have been included in the GIS database. These are located in three separate shapefiles (data layers) within the GIS, due to the incompatibility of polygon and line data. The totals for the three shapefiles break down as follows:

  • Types 1-4 (polygon features in palaeopoly.shp): 658 features
  • Types 5-6 (linear features in palaeoline.shp): 163 features
  • Type 7 (areas of ridge and swale in ridgeline.shp): 34 areas (123 ridge features)

Palaeochannel attributes

A number of text attributes were attached to each recorded feature within the GIS, as follows:

  • Unique ID: numbered from 1001 upwards; multiple ridges within the same area of ridge and swale are recorded under the same number (i.e. the unique ID refers to the area of ridge and swale rather than to individual ridge features).
  • Type: 1-7 as detailed above. Where types overlap (for example a cropmark followed by a field boundary), the lowest possible number is given (in this case 3: cropmark). Where more than one type occurs within the length of a feature (for example a depression which continues as a cropmark in a ploughed field), a decision will be made as to which type constitutes the majority of the feature. In both cases the additional information will be recorded in the Notes attribute.
  • Notes: additional descriptive information supplementing the Type category.
  • Notes 2: additional descriptive information, generally relating to parish boundary data.
  • NGR: an eight-figure National Grid reference given at a central point on the feature.
  • Photosource 1: the primary photograph on which the feature was identified and plotted.
  • Photosource 2: any other photograph which provided secondary information on the feature.
  • Mapsource 1: reference to any historic map on which the feature is shown; text description of how the feature is depicted (e.g. stream course, active channel, relict channel).
  • Mapsource 2: for use in future investigations
  • Borehole record: for use in future investigations
  • PalaeoPotential: for use in future investigations
  • Date in years AD/BC: for use in future investigations
