title = "Water Footprint (WFP) in Hydropower Plants Using Observed Meteorological Datasets: The Case of the Funil Hydropower Plant, Southeast Brazil",
abstract = "Water footprint (WFP) has been used to indicate the efficiency and sustainability of water resources. In hydropower plants (HPP), WFP is the water evaporated from the reservoir / the energy produced in a period (monthly or annually), in m3.GJ−1. The major issue in this case is that the water stored in the reservoirs is exposed to solar radiation and is evaporated, being a very significant water amount that is not used in other economic activities. The WFP in a HPP has been calculated using average meteorological datasets from the closest station, which has resulted in a biased calculation. However, WFP can also be calculated by considering net evaporation, the net water footprint (NWFP). In this chapter, we present a case study involving a HPP in the Grande River basin, southeast Brazil. WFP and NWFP were calculated over two consecutive hydrological years using observed local weather datasets and the temperature of the reservoir{\textquoteright}s water. The FPP has shown 29 (WFP) and 13 m3GJ−1 (NWFP) (the latter was 55% lower). Our results have demonstrated a reasonable efficiency of the water use for electric energy generation in this facility. In addition, when using the weather datasets in the reservoir{\textquoteright}s area and the thermodynamics of the reservoir, WFP calculation becomes more robust and reliable.",
