Moreover, the current development status of sedimentation simulation research in china was demonstrated and five big trends for the future development of sedimentation simulation technologies were analyzed. the geometric similitude, kinematic similitude and kinetic similitude between the lab model and the prototype for sedimentation simulation form the basis of three similitude principles, while three similitude rules, i. e., the suspension similitude rule, the particle movement similitude rule and the riverway distortion similitude rule can be deduced from the three similitude principles, and thee principles and rules are the basic theories for the development of physical simulation about the clastic sedimentation processes
