Available at: https://www.researchgate.net/publication/326131885_Measurement_methods_for_hydropower_resources_a_reviewEach hydropower plant is usually designed for specific amount of discharge and gross head. This paper presents the methods used to measure the discharge and gross head variables with additional of assessment tools. Discharge measurement methods covered include bucket, float, velocity-area, dilution, hydraulic structure and advanced discharge measurement while gross head measurement methods covered include topographic and DEM maps, hose level with pressure gauge, sight level, spirit level and advanced survey instruments. The assessment tools presented include SMART MINI-IDRO, Integrated Method for Power Analysis, VIPIDRO ASTE 4.0, Hydromatch, Hydrohelp and Renewable Energy Technology Screen tool. The assessment tools used to estimate the potential of hydropower resources in terms of energy, hydropower plant components and financial analysis. Therefore, this review paper indicated the possibility of conducting a pre-feasibility study of hydropower estimation by using the open access tools and accessible equipment in the carpentry and mason works, especially in the developing countries.enGross headHydropower resourceMeasurement methodsHydropower plantHydropowerHydropower toolsDischarge headArticle
