A numerical model is developed based on a two-layer flow model for the purposes of predicting the flow and the bed evolution of alluvial rivers with complicate geometries including the case of compound channel flow. The reasons for using a two-layer

Braided channels which are generally produced in mountain streams, vary spatially and temporally. The channel processes are composed of widening phase, bifurcating phase and merging phase.In this paper, flume tests are conducted to investigate wideni

Observational studies on the runoff, sediment yield and the sediment transport have been carried out in an experimental basin, the Ashiaraidani creek (6.5 km^2), which is a tributary of the Jintsu River.(1) The relation between sediment yield and rai

The flow characteristics of fine sands and water mixture is discussed in terms of experimented results concerning the flow resistance, sediment concentration profiles and sediment diffusion. (1) Flow resistance does not change so much in the range of

Field survey and observation were carried out for clarifying the real situation of sediment yield on a bare slope, sediment runoff in the steep channel, and debris flow on the Ashiaraidani creek (6.5 hA), which is a tributary of the Jintsu River.(1)

Braided channels are generally produced in mountain streams with very active sediment yields.Such channels vary spatially and temporally, which results in a big variation of the sediment discharge.The bed material is composed of a wide range of grain

In the previous paper^1)- the authors presented a bed-load equation which was derived from their constitutive relations of debris flow. The equation underestimates somewhat the bed-load rate in the range of non-dimensional shear stress smaller than 0

In most rivers in Japan, tolerable degradation occurs because of the sediment trap by the reservoirs upstream, and the severe gravel mining which was done during the period of rapid increase in economy.As a result, disasters during flood have been in
