Description
Paper presented at ICUD 2024
The work described in this abstract shows the development and application of a surrogate model, which transforms the difference between the temperatures in the water and sediment into a sediment depth estimation. Field measurements were performed in two gully pots, where sensors were installed to monitor the temperature and determine the sediment thermal properties as inputs of the surrogate model. Reference sediment depths were also measured to evaluate the performance of temperature-based systems. The study highlights the potential of temperature sensors for monitoring sediment accumulation in gully pots.
