2.1 Effects of Energetic Treatment,arges. In the case of a regulated fall, it also serves to obtain command at specific points along a canal, where the water surface has to be raised to enable an offtaking main or branch canal to be supplied. In both cases, a drop in water level is artificially created which results in the conversion

1. Important Parameters of Polymers,vestigated Italy. Equilibrium scour holes developed around the piers , boundary shear stress distributions , and flow characteristics in the soured zones were measured in the laboratory hi case of both round and lenticular nosed piers having length — width ratios of 2 and 3 , and placed at different
