Abstract

We present a new method for using temperature to infer bathymetric change of an artificial beach placed in the O.H. Hinsdale Wave Research Laboratory Large Wave Flume at Oregon State University. The temperature latency technique compares recorded temperature measured within the sediment with modeled temperatures expected to result from surface water temperature changes through time. Because surface-driven temperature changes are attenuated and lagged in time with deeper burial, we can estimate depth of burial by examining the time series of temperatures measured within the sediment relative to surface temperatures. Temperatures are recorded at more than 900 cross-shore locations across two depths using a fiber optic distributed temperature system (DTS) and at 2 cross-shore locations at two depths using stacked point thermocouples for DTS verification.

Data will be available in October 2021 by request from ctemps@unr.edu.
