A previous article described the Arkansas Offstream Reservoir Analysis (ARORA) model, which simulates operational characteristics of farm reservoirs used with groundwater to provide irrigation to soybean. Since the model is also structured to compute costs and incomes for specified situations, it may be used as a tool in comparing the relative benefits of various reservoir capacities and thus in identifying the best capacity for a particular scenario. This article describes how ARORA was applied to assess performance of reservoirs in situations with differing groundwater status, soil, and economic parameters. An analysis of the results shows that each of these variables can influence the performance of reservoirs as assessed on the basis of present worth of net incomes. The results also indicate that based on the same criterion, reservoirs are currently feasible under certain conditions, particularly when groundwater availability is limited.
