    Where your farm pond design is in a stream valley, the main watercourse should be diverted around the side, in its own channel, or in a newly created bypass. At a point slightly above the upper end of the farm pond design, the stream should be slowed and widened by building a loose stone or masonry dam, to form a small pool from which a pipe ...

    In settling analysis and design, the particle distribution is usually not given. What is known instead as the outcome of a lab test with a settling column. A 1-to 2-m long column is filled with the turbid water and is left unperturbed in the vertical position for some time. During this time, particles fall down and accumulate on the bottom.

    A settling basin, settling pond or decant pond is an earthen or concrete structure using sedimentation to remove settleable matter and turbidity from wastewater.The basins are used to control water pollution in diverse industries such as agriculture, aquaculture, and mining. Turbidity is an optical property of water caused by scattering of light by material suspended in that water.
