Abstract
Measuring sedimentation in water reservoirs typically relies on point measurements or bathymetric surveys. This provides only a snapshot of sedimentation in time or space leading to unreliable estimations of storage capacity, particularly in catchment areas affected by changes of land use and extreme climate events. We demonstrate a new approach for continuous monitoring of sedimentation using Distributed Temperature Sensing (DTS) coupled with a heating source/cable. The DTS technology measures temperature at ~1 m resolution and is used to monitor temperature in real time across long distances. In this application, we use DTS to detect sedimentation based on the thermal propagation differences of water and solids. The use of a heating source removes the dependence of the DTS signal on diurnal temperature, providing better control for sedimentation monitoring. Experiments were conducted in large containers using a medium grain sand (average grain diameter = 344 µm). Point-based temperature sensors were initially employed to account for
