In this observation, a suction pump was used to sample sufficient amount of suspended sediments for grain size analysis. The method was devised for the observation, and worked successfully. Vertical distributions of sediment concentration for several grain sizes which compose suspended sediments were obtained. This enabled us to do numerical simulations of beach evolution taking the composite character of suspended sediments into consideration. Results are compared with the ones obtained by a conventional simulation method which assumes single grain size composition of beach materials, and discussed. The vertical distribution profiles of the concentration of suspended sediments are also compared with existing models and discussed.}, pages = {259--265}, title = {浮遊砂の粒度組成に関する現地観測}, volume = {33}, year = {1991} }
