River - Sediment Yield

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:

    Whether, if you yield not to your father’s choice,
    You can endure the livery of a nun,
    For aye to be in shady cloister mewed,
    To live a barren sister all your life,
    Chanting faint hymns to the cold fruitless moon.
    Thrice blessed they that master so their blood
    To undergo such maiden pilgrimage.
    William Shakespeare (1564–1616)
