Results of an experimental study on the effects of different concentrations of wash load on the size of bed features and resistance to flow in a laboratory flume are *** experiments were carried out under different hydraulic conditions in a 30 m long,0.204 m wide and 0.5 m deep tilting flume under clear water condition and in the presence of different concentration of wash load in the *** bed material used consisted of uniform sediment of size 0.96 *** of the data indicates that the characteristics of the bed features change and friction factor increases in the presence of different concentration of wash load in the *** reasons for changes in the characteristics of the bed features and increase in friction factor in the presence of wash load are identified and a relationship for predicting friction factor in the presence of wash load has been established.

Elaborate experiments were performed in a 30 m long,0.5 m deep and 0.2 m wide laboratory flume to study the process of infiltration of fine sediment into the pores of coarse sediment forming the channel bed *** concentrations of suspended load of fine sediment of size 0.064 mm were passed over the channel bed made up of three different types of coarse sediments;two uniform and one *** proportion of fine sediment infiltrated into the pores of bed material for each equilibrium concentration of suspended load of fine sediment in the flow was studied during several experimental *** proportion of fine sediment within the pores of bed material increased with an increase in the equilibrium concentration of suspended load of fine sediment in the *** process continued till the pores within the coarse sediment bed were filled up to the capacity with the fine sediment transported by the flow in *** theoretical value was identified for limit for maximum proportion of fine sediment that can be present within the pores of bed *** further increase in the concentration of suspended load of fine sediment in the flow,deposition of fine sediment occurs on the surface of the flume bed in the form of ripples of the fine *** condition is defined as ’depositional condition’.Experimental observations on these and related aspects are presented herein.
