The primary disadvantage associated with the two stage drainage ditch is the upfront cost of the earthwork necessary to increase the existing channel for the benches to be constructed. Construction costs for such earthwork are contingent upon the watershed size and depth of the ditch and approximately range from $5–20 USD/linear foot. [6]
In geotechnical engineering, watertable control is the practice of controlling the height of the water table by drainage.Its main applications are in agricultural land (to improve the crop yield using agricultural drainage systems) and in cities to manage the extensive underground infrastructure that includes the foundations of large buildings, underground transit systems, and extensive ...
