The general arrangement and location <br />of project features is shown in Figure I-I. <br /> <br />1".. Operation.of Alternative Project C<mfigurations <br /> <br />The many possible project configurations were. examined. through <br />project operatIon studies which simulate,the operation, and .administra- <br />tion of a specified project. Each operatIon study 01' simulation or ' <br />"run" represents 35 years of monthly operation. Each simulation is <br />the computation of the amount of water distributed to each canal, each <br />reservoir and each group of irriglltion water, U/iers according to an <br />established set of rules. These operating' rules ar,e con,sist"nt w,ith <br />the existing water rights system, .nth hydrologic. principles and with <br />assumptions made 'about the operation ofa ',consolidat,ed. irrigation <br />system il1corporaUng new, storage and addItional canals. <br /> <br />The operation studies began with the simulation ,of the existing <br />system. This is the simulation of operations with the existing canals <br />operating to serve existing lands ,in Scenario A and then expanded to <br />include ne" lands which might be served in Scenarios ./3, C and D. <br />These base simulations show an irrigation water shortage which can be <br />used as the basis for measuring the benefits .of. proposed project, <br />features.
