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

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

Coefficient of expansion - data,or drinking (the Romans developed a highly sophisticated supply system with aqueducts, syphons etc. for this purpose) and for irrigation. Even at this stage then, it was necessary that the discharge in conduits and canals be regulated so as to prevent flooding and also to distribute the available wa
