Previously developed suites of models integrate irrigation water supply and demand management for simplified surface reservoir supply systems. A central stochastic dynamic programming model is supported by simulation models, including a soil water-plant growth model. This modeling is extended herein to include decisions about timing and quantity of reservoir water releases into the delivery system, resulting in the integration of supply, demand, and delivery management. Irrigators have rights to percentages of reservoir capacity, reservoir inflows, and downstream tributary flows. Natural rivers are the supply channels in the study area. Large on-farm water storage exist for storing regulated and unregulated river flows available to the irrigators. Farms can be many days flow from the reservoir, requiring orders for reservoir releases to be lodged before the arrival of a previous order. The probability of unregulated flows from tributaries downstream of the reservoir further complicates ordering decisions. Abandonment of irrigated area to rain-fed status occurs at two levels, forced abandonment if insufficient water is available at the farm when the irrigation-trigger soil water deficit is reached, and planned abandonment to save water for possible later use. The need for forced abandonment is determined by simulation models; planned abandonment decisions are derived by stochastic dynamic programming. Results show annual net revenue means and standard deviations as functions of different capacities of the on-farm storages and water supplies from either regulated or unregulated flows, or both.

Capacity sharing is a new way of defining and allocating rights to flowing and stored surface water in a river valley. It is as if each user of water, or group of users, has their own small reservoir on their own small stream to manage independently from others. Hence it provides a very sound basis for the market allocation of private property rights, about which there has been a recent surge in the literature, especially with respect to the western United States. A similar surge, although spread more widely both in its geographic emphasis and across academic disciplines, is in the literature on common property approaches to resource management. Whereas the common property approach may work well for small water resource systems, it is inappropriate for the management of large systems. However, because capacity sharing minimizes the interdependence of behavior between users of system water, it provides a very good basis for dividing up such large systems among a number of independent, multi-purpose groups each operating their sub-system as a common property resource. Similarly, capacity sharing allows a harmonious mix of private property and common property resource management of the sub-systems within river valley systems.
