Physicists, engineers, mathematicians, statisticians, and geologists have been investigating sedi- sedimentation processes and their impact on sediment transport plays a. Actual sedimentation basins are rectangular, square, or circular in plan area. A single-rectangular basin will cost more than a circular basin of the same size; however, if numerous tanks are required, the rectangular units can be constructed with common walls and be the most economical.

Chapter preview. Currents can be beneficial in that they promote sedimentation of the particles. However, currents also tend to distribute floc unevenly throughout the basin; as a result, do settle at an even rate. Current problems can be reduced by proper design of the basin and installation of baffles can help prevent currents from short circuiting the Size: KB.
