Assume lor a given time step of <br />the simulation that the time-series tables containing inflow data. reservoir release <br />rule data. and required allocations to the diversions, have sent these data, as <br />appropriate for the period being simulated. to their connected nodes, as shown in <br />Figure 5. It is now the task 01 each water object to solve, if possible, its mass <br />balance equation (Equations 1 and 2). When an object's mass balance equation <br />can be solved, it must send, via the connecting links, the necessary information to <br />the upstream or downstream objects. <br /> <br />Assume reservoir release policies for each of the reservoir nodes are defined by <br />release targets contained in the lime-series tables or by the policy statements. <br />Finally, assume that there is a-,}~inim.Jm flow requirement that must be met down- <br />stream 0' node 7, the most downs-rre~nver system. <br /> <br />The following steps might take place in the process 01 obtaining an equilibrium <br />among the data contained by each object. <br /> <br />1. Reservoir Node 1 receives from its input time-series table the period's inflow <br />and the amount to be released. This release is placed in the outflow slot of <br />Node 1. It is now possible for Node 1 to solve its mass balance equation for <br />ending storage. Hence Node 1 is placed on the object activation queue. <br /> <br />h A\/P <br />l~ <br />\. {,L yJ "L <br />~\,\d ~~ ~* <br />.):0 "'":\ _.L~\If' <br />VJ/',>ll" ~!J'" <br />c,o\~ <br />toJl' <br /> <br />I~j ~~ <br />Node 1 <br /> <br />t <br /> <br />Node 3 <br /> <br />14 <br /> <br />RSS Concepts and Methodology <br />
