Transport of fines/wash load through channels - A review
A lot of wash load comes to the streams during the rainy season due to the erosion of soil from the catchment and known to flow practically without settling on the streambed. The presence of wash load is known to affect the resistance to the flow. The effect of its presence on transport of bed material load is not well known. The present paper is devoted to a review of the studies regarding concept of wash load, changes in resistance to flow due to the presence of wash load, the effect of presence of fines in suspension on the transport of bed-material. The presence of excessive amount of fines in the stream bed adversely affect the spawning of salmon and other species of fish.
