The present study aims to evaluate the efficiencies of conducting channels bypass Commission Sausal User Chicama Valley , in relation to the requirement of water supply in distribution , for which the method was applied field data collection and systematization of information. In the field phase , through gauging input and output at each point of the stations were established along the canal, with the results obtained will serve to verify the requirement for the provision of appropriate water according Distribution Plan Water , as well as identify areas for expanding agricultural frontier. In the phase of systematization of field information was obtained driving efficiency in the Pampas Jagiiey channel is 78 % in the channel is 65 % Salinar Burning in the Barranca Channel Plan 2 is 85 % and channel Chicamita it is 84 %. It should be noted that the value of driving efficiency depends dire...
