These data are generated in the lab and are about the erosion of an unsaturated soil bed by collisional flow.
The data uploaded include:
(1) Erosion profile - The erosion depth measured by using erosion columns and the calculated erosion rate for each test;
(2) Soil bed shear strength - The data compulsory for estimating the shear strength of the unsaturated soil bed;
(3) Flow-depth& velocity - Time series data about the flow depth (measured by an ultrasonic sensor) and velocity of the flow (extracted using the PIV technique) at the interface between the non-erodible and erodible beds;
(4) Flow depth & pore pressure - Time series data about the flow depth (measured by an ultrasonic sensor) and the pore water pressure (measured by a pore pressure transducer.
