Patent ID: 7975532

Claim:
A transportable system for in situ measuring of erodibility comprising: a configuration having a length, a width and a depth, an open top and an at least partially-open bottom, at least two sides defining said length and said depth and having top and bottom edges, two ends defining said width and said depth and having top and bottom edges, at least one inlet located on one of said ends and at least one outlet located on the other of said ends, wherein said at least one inlet and said at least one outlet at least facilitate movement of a fluid; mounts to affix said configuration approximately flush against a surface so that bottom edges defining the periphery of said configuration enclose a section of said surface and at least reduce fluid leaks along said periphery, wherein said configuration emulates a hydraulic open channel having smooth vertical sides such as may be employed in a research laboratory; a source of fluid; a pump in operable communication with said source of said fluid and said configuration, wherein said pump at least provides said fluid from said source to said configuration; at least one instrument for at least collecting data while said fluid flows through said configuration, wherein said fluid exits said system at said outlet to permit said instruments to collect said data.
