This paper presents a spatial equilibrium approach for screening level water resources assessment. This approach complements traditional hydrologically based water resources assessment methods by providing a model capable of evaluating national‐regional strategies with respect to four principal objectives of water resources policy: supply‐demand balance, economic efficiency, cost recovery, and equity. The proposed approach has a number of advantages. First, it provides a simple yet generalizable representation of the spatial environment at a number of scales. Second, the assessment is freed from the constraint of requiring a highly detailed hydrologic description. Third, an objective‐constraint structure provides the basis for defining, organizing, and collecting the data necessary for the assessment. Finally, simulation is used in conjunction with optimization to evaluate alternative allocation scenarios. A case study in Cyprus demonstrates use of the model for policy analysis.
