This dataset provides the measurement data of tsunami sediment transport laboratory experiment (TSTLE) project conducted in 2014-2016. The dataset includes the following materials. All files are encoded with UTF-8 format. 1. Fixed-bed: water level (WL), horizontal velocity (U), and vertical velocity (W) measured in the fixed-bed channel 2. Movable-bed: water level (WL), horizontal velocity (U), vertical velocity (W), and concentration (C) measured in the movable-bed channel 3. Topography: pre- and post-experiment and corrected difference (*) 4. Deposits (Bulk): area density, D50, Dvcs, Fe2O3 content, and Al2O3 content 5. Deposits (Layers): Sampling depth, D50, Dvcs, Fe2O3 content, and Al2O3 content (*) We corrected bias error which pre- and post-experimental measurements may include.
