Bed Load Measurements and Testing of the Gravel Transport Sensor (GTS)

There are several limitations to the current methods of measuring bed load in gravel bed stream. To combat these limitations a new devise, the Gravel Transport Sensor (GTS), has been developed by D & A Instruments. Preliminary testing on a GTS prototype was conducted to examine the instrument's ability to detect different size particles over a range of flow conditions. Preliminary results showed the ability of the GTS to detect particles moving as bed load reduces with a reduction in particle size.
