Sediment Yield
Sediment yield is the total quantity of particulate matter (suspended or bedload) reaching the outlet of a drainage basin over a fixed time frame. Yield is usually expressed as kilograms per square kilometre per year. Sediment delivery processes are affected by a myriad of factors such as drainage area size, basin slope, climate, sediment type (lithology), vegetation cover, and human land use / management practices. The theoretical concept of the 'sediment delivery ratio' (ratio between yield and total amount of sediment eroded) captures the fact that not all of the sediment eroded within a catchment reaches the outlet (due to, for example, deposition on floodplains). Such storage opportunities are typically increased in catchments of larger size, thus leading to a lower yield and sediment delivery ratio.

Famous quotes containing the word yield:
“Never yield to that temptation, which, to most young men, is very strong, of exposing other peoples weaknesses and infirmities, for the sake either of diverting the company, or of showing your own superiority. You may get the laugh on your side by it for the present; but you will make enemies by it for ever; and even those who laugh with you then, will, upon reflection, fear, and consequently hate you.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (16941773)
