In this paper, the corresponding diameter of sediment in prototype is determine by using Shield's parameter. This simulation has been undertaken to similitude the relationship between prototype and its model. A model and prototype are designed to be similitude geometrically, dynamically and kinematically. The studies regarding sediment transport similitude for hydraulic modeling, a very few researcher gives the predictive methodologies. Firstly Shield was started to consider sediment particle motion after taking into account, the forces act on the sediment particles and then afterward apply the principles of similitude similarity. The sediment used in undistorted model(tiling flume) is sieved river sand. The mechanical sieve shaker, analysis was used to determine the mean particle size (d50=0.828mm) and the corresponding diameter of sediment in prototype is determine by using Shield's parameter which predict sediment size (d50=41.43mm).
