“…Correlation analysis deals with the research and quantification of the connection by mixing and quantifying the connection between the observed phenomena, i.e., variables. The RAPS method can be applied in all research areas but is mostly used to analyze a river flow from a hydrological point of view [3]. This method has quite a wide range of applications, especially in hydrology [4].…”

“…Also, the problem is the anthropogenic impact that occurs by building dams and accumulations, over-pumping of the groundwater, and building a hydropower plant, which [2] analyses to show changes in the hydrological regime caused by human activity in their case by the operation of HPP Gojak. [3] had determined that the river Gornja Dobra has the potential to build small hydropower plants, especially kinetical.…”

The variability of river flow depends on environmental changes that are due to either natural or human causes. Measuring river flow is an essential activity in the domain of hydrology that gives valuable information on river conditions. An appropriate understanding of the conditions of the water courses and a good anticipation of all possible situations and problems that may arise are essential. The average daily river flow time series will be analyzed on the case study of river Gornja Dobra in Croatia. Rescaled Adjusted Partial Sums (RAPS) analysis with correlation analysis will be applied to the time series provided by two available limnigraph measurement stations, Turkovići and Luke. The examples will give insight into the ability to forecast river flows in the analyzed case study and other regions in Croatia and the world. The presented methodology could be used for flood protection, determining the hydroenergy potential of the rivers, irrigation, and many other purposes.

“…To establish the efficiency of hydropower production, interdisciplinary studies should be conducted; hydrologic flow and climate change influence hydropower production [11,12] The small-scale production of hydropower generates consistent extensive growth and gains a large share of the total; its fluctuation must be evaluated using hydrologic flow and other influencing factors such as irrigation and water supply [13,14]. Other studies, besides hydrology and hydrogeology are considered to estimate the efficiency and opportunity of hydropower development [15].…”

Renewable sources of energy production are some of the main targets today to protect the environment through reduced fossil fuel consumption and CO2 emissions. Alongside wind, solar, marine, biomass and nuclear sources, hydropower is among the oldest but still not fully explored renewable energy sources. Compared with other sources like wind and solar, hydropower is more stable and consistent, offering increased predictability. Even so, it should be analyzed considering water flow, dams capacity, climate change, irrigation, navigation, and so on. The aim of this study is to propose a forecast model of hydropower production capacity and identify long-term trends. The curve fit forecast parabolic model was applied to 33 European countries for time series data from 1990 to 2021. Space-time cube ArcGIS representation in 2D and 3D offers visualization of the prediction and model confidence rate. The quadratic trajectory fit the raw data for 14 countries, validated by visual check, and in 20 countries, validated by FMRSE 10% threshold from the maximal value. The quadratic model choice is good for forecasting future values of hydropower electric capacity in 22 countries, with accuracy confirmed by the VMRSE 10% threshold from the maximal value. Seven local outliers were identified, with only one validated as a global outlier based on the Generalized Extreme Studentized Deviate (GESD) test at a 5% maximal number of outliers and a 90% confidence level. This result achieves our objective of estimating a level with a high degree of occurrence and offering a reliable forecast of hydropower production capacity. All European countries show a growing trend in the short term, but the trends show a stagnation or decrease if policies do not consider intensive growth through new technology integration and digital adoption. Unfortunately, Europe does not have extensive growth potential compared with Asia–Pacific. Public policies must boost hybrid hydro–wind or hydro–solar systems and intensive technical solutions.

“…Such is the motivation for finding and applying a suitable method, which should be not complex to use and should be transparent for the comprehensive and qualitative analysis of the observed time series. The Rescaled Adjusted Partial Sums (RAPS) method is appropriate for time series analysis in hydrology [6][7][8]. In addition, it was used in this paper/research.…”

Concerning the media’s properties, there is always a possibility of changing groundwater flow conditions surrounding hydroelectric power plants. Causes for such events could be natural or anthropogenic, which is, in many cases, not so obvious to determine. In addition, determining a period when changes in the groundwater flow occur is a complex task. All of the above mentioned are of crucial importance due to the operational work of hydropower plants, i.e., the optimization of the inflow and outflow of the water in the turbine, regardless of the hydropower plant type. All types listed require a particular approach for solving such issues. Rescaled Adjusted Partial Sums (RAPS) is an appropriate time-series analysis method. In this specific case, observed fluctuations in the time series of the groundwater levels could lead to conclusions about possible irregularities in the shallow as well as the deep zones of the underground water. The concept was shown in this paper in the example of the hydroelectric power plant Mostar dam in Bosnia and Herzegovina. It should be noted that the defined methodology was a novel procedure for analyzing and determining the pathways of the flow of groundwater in the surrounding hydropower plant dams. In other words, such analysis could be conducted without the need for complex and expensive drilling and geophysical surveys, tracing, and all other methods.
