Abstract: Hydraulic simulation of bed proceases having an account ofmain criteria of similerity needs the availability of completegeometric similarity,automodelity and mobility of artificialsand material.In a variety of cases whenit is impossible toget geometric similarity of sand grains,light material is usedBs B model.However even it does not aliow to get simileritysince natural and artificial drift disturbs the identity of theflow character.In similar ceses the use of natural and artifi-cial coefficients of pressure lo88 is rather successful suffici-ently reaching the similarity of wash-out proceases both in aut-omodel and transitinal region of motion.
