“…A multi‐channel Syscal Pro Switch 48 resistivity system (IRIS Instruments, France) was used to complete the survey. As this system is limited to 48 electrodes at a time, the roll‐along method was used to record the full survey line through three successive segments, with 50% overlap (i.e., electrode numbers: 0–48, 24–72, 48–96) (K. Robinson et al., 2022). The multi‐gradient electrode array was deployed (e.g., Power et al., 2018) with a total of 4,183 measurements.…”

Coastal zones are the most populated and developed areas worldwide. Currently over half of the global population resides in coastal areas and this is expected to increase in the future based on current trends of coastal migration and population growth (Small & Nicholls, 2003). Sandy beaches, which occur along marine coastlines and along inland coastlines that are adjacent to large inland lakes, make up more than one-third of the ice-free global coastline (Luijendijk et al., 2018). Many sandy coastlines worldwide are threatened by the landward movement of the shoreline, known as shoreline recession. Shoreline recession, which is caused by increases in coastal water levels (i.e., sea level rise or lake level changes) combined with shoreline erosion, is expected to increase as the climate changes (e.g., higher frequency and more intense storm events) and in response to anthropogenic development (Bird, 2008). Luijendijk et al. (2018) found from satellite image analysis that 24% of the world's sandy beaches are eroding at rates exceeding 0.5 m/yr, with only 48% of sandy beaches considered stable. For the Laurentian Great Lakes, which have more than 6,000 km of permeable shoreline (Government of Canada -Environment and Climate Change Canada and U.S. EPA, 2009), shoreline recession caused by interannual lake water level fluctuations combined with erosive storm events is an increasing challenge. Lake water level fluctuations up to one to two m occur along large lacustrine shorelines, such as the Great Lakes, approximately once a decade (Argyilan & Forman, 2003;Sellinger et al., 2008).It is well established that shoreline recession along marine and inland coastlines has severe economic, social and environmental consequences due to impacts including land and habitat loss, property damage, and reduced revenue potential from tourism and industry (Mukhopadhyay et al., 2018;Theuerkauf et al., 2019). As such, this is an active area of research, with studies generally focused on monitoring shoreline changes (e.g., Burningham
