One of the parameters needed in order to make use of the Manning equation for open channel flow calculations is the hydraulic radius of the channel cross section. Rivers, canals, and uncovered flumes are open channels. [Hide this line]. Archimedes - the ingenious scientist of the ancient world - recognized the functionality of pumps as early as in the middle of the 3rd cent. As mentioned in the introduction, the accuracy of seepage loss estimations will depend on how well we succeed in determining the areal pattern and stratification of any pervious soils in the pond area and along the trace of the filling canal, and the permeability coefficient 'k' of these soils.
