The evaluation was originally intended to comprise the excavation of 170no. trenches, each measuring 30m long by 2m wide, as per the agreed WSI (AECOM 2021) and Supplementary Method Statement (CA 2021). However, after the commencement of fieldwork a decision was taken to remove all flood compensation areas listed in the WSI from the scheme (see AECOM 2021 section 4.12), leaving a total of 70no. trenches to be excavated. As this was finalised after trenching had already progressed beyond land parcel 13, the trenches in that parcel were retained in the overall numbering sequence for the remaining trenches although they remained unexcavated. Further changes in the trenching requirements over the course of the fieldwork meant that trench 79 in area 11 should have been renumbered to 75 but as the trench had been fully investigated and recorded at the point at which the numbering sequence was changed then the number 79 was retained in order to maintain coherence within the primary archive. Due to land access not being granted then trench 68, in area 27, was also subsequently omitted from the scheme with the result that 69no. trenches were excavated in total. The trench locations were chosen to target anomalies identified by a previous programme of geophysical survey (AOC 2021), as well as to test apparently blank areas in the survey and as a means of prospection for remains of a type or period that may not typically respond to geophysical survey, as specified in the brief (OCCAS 2021) and detailed in the agreed WSI (AECOM 2021) and Supplementary Method Statement (CA 2021). In general, the correlation between geophysical anomalies and the features identified in the trenches was poor, with most features predicted by the geophysical survey not encountered and, conversely, investigated features in many cases not matching the geophysical survey results. Trenches were set out on OS National Grid co-ordinates using survey grade Real-Time Kinematic (RTK) Global Navigation Satellite System (GNSS) Leica GPS equipment and scanned for underground services by appropriately trained members of staff using Radiodetection Cable Avoidance Tool and Signal Generator equipment. Overburden was stripped from the trenches by a mechanical excavator fitted with a toothless grading bucket. All machining was conducted under archaeological supervision to the top of the natural substrate, which was the level at which archaeological features were first encountered.
