Dataset on sensitivity of water-energy nexus to Dez Dam power plant operation

This article explains the time-series data for sensitivity of water-energy nexus to Dez Dam operation located at Dez basin in the southeast of Iran for a period of 54 years (648 months) from October 1964 to September 2018. The utilized data included outflow of the turbine, reservoir inflow, reservoir volume, evaporation, precipitation, spillway, total outflow of the reservoir, elevation, power generation and demand. In this article, operation of Dez Dam is examined for 54 hydrologic years (1964-2018), considering reducing the full supply level (FSL) gradually from its current value to the minimum possible value, increasing the minimum operating level (MOL) gradually to the maximum possible level and operating the Dam at a constant operating level (COL). Also, the concept of water-energy productivity (WEP), defined as the amount of energy produced per unit of water lost in the process, is proposed to measure water-energy nexus (WEN) to changing Dez Dam operation policy. Analysis of the WEN in the context of Dez Dam operation is imperative for improving decision making in the quest for efficient resource use and management.
