A transportable system and method for determining erodibility of a surface such as that of an earthen embankment. Select embodiments deploy an instrumented portable bottomless open channel test enclosure, either a manifold or an inlet to a flume, and sufficient piping and valves to provide a fluid flow over a surface of interest. Select embodiments use mounts, such as spikes, affixed to the bottom edges of the open channel to position the channel flush against the surface, thus reducing or preventing fluid leakage along the periphery. Select embodiments emulate a hydraulic open channel having smooth vertical sides as may be found in a civil engineering laboratory. Select embodiments incorporate an external pump, gauges for taking measurements while fluid flows through the channel, an inlet and an outlet and a re-cycling sub-system from the outlet to the inlet.
