This dataset contains measurements of hydraulic head and saturated hydraulic conductivity together with porewater chemistry from banks and riverbed sediments in six river reaches of contrasting geology (clay, sand, chalk) in the Hampshire Avon. Falling and rising (slug) test data were used for computation of saturated hydraulic conductivity. Hydraulic head measurements were obtained from pressure transducers installed in piezometers between Summer 2013 and Summer 2015. Samples for porewater chemical analysis were collected from porewater sampling tubes on the piezometer network between Summer 2014 and Summer 2015.

All data were generated by the authors with help from field and laboratory technicians. All hydraulic head data generated by the pressure transducers were checked fortnightly (when possible) against manual measurements. As chemical data were generated, checks were made to ensure accuracy (certified reference materials) and precision (repeat measurements) were within accepted tolerance limits. We ensured measured values fell within the calibration range and re-analysed samples where necessary.
