Abstract
The transport of sediment through a river as bed load helps to define the channel geomorphology. Measuring bed load is difficult and often problematic due to the high flow velocities of which they are often associated. A non-intrusive method of measuring bed load with an Acoustic Doppler Current Profiler (ADCP) in mixed-sized sediment Central Texas stream is proposed. Velocity data extracted from ADCP software combined with physical measurements of the channel bed composition can be used to determine a total bed load transport rate. Using this faster and safer measurement technique, it is the goal of this research to improve the collection and quality of available bed load data.
