A small trial-trenched evaluation in 2016 produced small quantities of Roman, medieval and post-medieval finds in the river silts. The report suggests these were probably derived from centuries of dumping rubbish on the river edge. The trench revealed modern soils (L1, 0-1.05m), post-medieval dump (L2, 1.05-1.31m), medieval/post-medieval river silts and gravels (L3-L5, 1.31m-2.24m, starting at 5.45m AOD), and Roman river silts (L6, starting at 2.24m deep, 4.5m AOD).
