“…Alashan et al stated that the classical methods are applicable only for the river basins with low flow potentials and the results are also approximate. They provide calculation opportunity for theoretical gross hydropower generation between the two points without consideration in between.…”

“…The classical hydropower calculation methodologies are the single‐point, double‐point, and subdrainage methodologies . The single‐point method is the most commonly used practical formulation that is useful for preliminary hydroelectric power, P , calculations, which expresses it as equal to γ times of the discharge, Q in m 3 /s, multiplied by the falling head, H in m,

“…In order to overcome the assumptions that lead to a certain extent to shortcomings in the classical hydropower calculation methods, ETM is suggested for refining the gross hydropower potential calculation . The description of the ETM is presented in Figure with three subbasins within the main drainage area each with areas A 1 , A 2 , and A 3 and corresponding elevations as h 1 , h 2 , and h 3 .…”

Summary This paper is concerned with innovative approaches to renewable energy sources computation methodologies, which provide more refined results than the classical alternatives. Such refinements provide additional improvements especially for replacement of fossil energy usages that emit greenhouse gas (GHG) into the atmosphere leading to climate change impact. Current knowledge gap among each renewable energy source calculation is rather missing fundamentals of plausible, rational, and logical explanations for the interpretation of results. In the literature, there are rather complicated and mechanically applicable methodologies, which require input and output measurement data match with missing physical explanations. The view taken in this review paper is to concentrate on quite plausible, logical, rational, and effectively applicable innovative energy calculation methodologies with simplistic fundamentals. For this purpose, a set of renewable energy methodological approaches is revisited with their innovative structures concerning solar, wind, hydro, current, and geothermal energy resources. With the increase in the renewable energy utilizations to combat the undesirable impacts of global warming and climate change, there is a need for better models that will include physical environmental conditions and data properties in the probabilistic, statistical, stochastic, logical, and rational senses leading to refined and more reliable estimations with application examples in the text. Finally, new research directions are also recommended for more refined innovative energy system calculations.

“…The HE generation unit located next to each dam provides electrical energy to be used in case of need if there is sufficient water behind any dam. There are various studies on the conversion of water power to electricity 12‐15 . For example, river‐type HE studies convert surface flow kinetic energy into HE for electricity generation 16…”

Summary Human activities are directly related to fossil fuel consumption and cause global warming and climate change effects by emitting greenhouse gas into the lower atmosphere. To reduce and adapt to such effects, renewable energy sources such as surface dams, including hydroelectric energy (HE) generation units, are gaining importance. In the current literature, HE potential calculations are based on formulations that are quite simple, clear and do not distinguish between different situations. In this paper, two classification methodologies are proposed for better assessment of HE production. The first one is based on the concept of the hypsographic curve to distinguish different drainage basin features into “Young,” “Mature” and “Old.” The second classification takes into account the newly defined energy index (EI) principle, which helps to classify the HE generation capability of drainage basins into “Very low,” “Low,” “Normal,” “High” and “Very high.” The application of the proposed methodology is presented for three drainage basins from the upstream sub‐basins of the Tigris River in Turkey. A comparison of the results shows that the proposed methodologies not only give numerical values but also sets linguistically rational and logical rules for the HE potential of a drainage basin. In the upstream basin of the Tigris River, the EI values vary between 0.705 and 0.122, corresponding to the “High” and “Low” categories, respectively. It is recommended that these two classification procedures be considered before the construction of any dam for HE production.

“…Among all the publications we reviewed, about 90% of scientific articles present evidence on the existence of global warming or global climate change [6][7]. Alashan et al, (2015) indicates that producing energy is very important, but that it is even more important to produce clean, sustainable, and inexhaustible energy sources with marginal pollution effects that are almost negligible in practice (i.e., hydropower, solar, wind, wave, geothermal, and hydrogen energy, among others) [8]. According to Toprak (2014) and , hydropower is a key strategy to protect fresh water resources (i.e.…”

Abstract-It is common knowledge that both fresh water and precipitation have no homogeneous mixture temporally or spatially on the earth planet. Transportation of water from one region to another has always been a part of human existence. The transfer is achieved by water conveyance structures (i.e. channels, pipes, tunnels, galleries, and drains). However, the flow in such structures occurs hydraulically and can be divided into two main classes: (1) pipe flow and (2)
