In the North Atlantic regional ( NAR ) study the supply model was designed to complement the demand model. The level of complexity of the supply model was developed from a balance of limits of resources and time available and the need to capture certain characteristics of the system. The resulting model is a mathematical programing model minimizing efficiency costs expressed in annual terms. Those cost curves that are nonlinear are approximated by using piecewise linear functions. It is a static annual model based on a critical period analysis and selected risk levels. The model incorporates the cost curves for supply from the headwater and mainstream storage, groundwater, desalting for 50 subbasins of the planning area and for selected interbasin transfer possibilities. Hydrologic and in‐stream use constraints are incorporated. The costs are minimized subject to meeting these and the set of demand constraints. The model produces a configuration of supplies for the 50 subbasins to meet the particular demand sets produced by analyzing the demand model. Objectives other than efficiency can be reflected to some extent through manipulation of the objective function and the constraints.
