An experimental investigation into the general erosion within a long contraction problem is reported. The experimental results are used to verify Straub's theoretical one-dimensional model for general erosion. Local scour near the side walls in the inlet region was also measured and the results are reported. Two different sizes of sand were used in the experiments.
