The capacity of hydroelectric power plants (HPPs) in the Russian Federation (RF) exceeds 50 GW. It is about 20% of the total capacity of all power plants in the country. The Volga River basin is the biggest in Europe with the catchment area of 1 360 000 km2. It covers the most populated and most industrialized part of the European Russia. The largest cascade of reservoirs in Russia and Europe is the Volga-Kama cascade (VKC) constructed in 1930–1980. It consists of 12 great water reservoirs and HPPs with total capacity about 12 GW. The main peculiarity for the VKC management is the combination of different requirements by various economy sectors: safety, energy, navigation, water needs for domestic and industrial services, agriculture and fishery, recreation and ecological rules. These sectors often make conflicting demands for the VKC operation. The VKC management principle is to balance and satisfy all of them taking into account the changing climate and economical effectiveness. Modern decisions for the VKC management are based on two principles. First is the constant optimization of the whole VKC management rules, taking into account both climate change and the Strategy of the country development. The second is the constant technical modernization of the VKC equipment to achieve the best economical effectiveness and safety for ecosystems and population.

Data Driven Approach

Power plants are required to supply the electric demand efficiently, and appropriate failure analysis is necessary for ensuring their reliability. This paper proposes a framework to extend the failure analysis: indeed, the outcomes traditionally carried out through techniques such as the Failure Mode and Effects Analysis (FMEA) are elaborated through data-driven methods. In detail, the Association Rule Mining (ARM) is applied in order to define the relationships among failure modes and related characteristics that are likely to occur concurrently. The Social Network Analysis (SNA) is then used to represent and analyze these relationships. The main novelty of this work is represented by support in the maintenance management process based not only on the traditional failure analysis but also on a data-driven approach. Moreover, the visual representation of the results provides valuable support in terms of comprehension of the context to implement appropriate actions. The proposed approach is applied to the case study of a hydroelectric power plant, using real-life data.

Carbon Neutral

Global warming contributes to the worldwide goal of a sustainable carbon-neutral society. Currently, hydroelectric, wind and solar power plants are the most competitive renewable technologies. They are limited to the primary resource availability, but while hydroelectric power plants (HPPs) can have storage capacity but have several geographical limitations, wind and solar power plants have variable renewable energy (VRE) with stochastic profiles, requiring a substantially higher investment when equipped with battery energy storage systems. One of the most affordable solutions to compensate the stochastic behaviour of VRE is the active participation of consumers with demand response capability. Therefore, the role of citizen energy communities (CECs) can be important towards a carbon-neutral society. This work presents the economic and environmental advantages of CECs, by aggregating consumers, prosumers and VRE at the distribution level, considering microgrid trades, but also establishing bilateral agreements with large-scale VRE and HPPs, and participating in electricity markets. Results from the case-study prove the advantages of CECs and self-consumption. Currently, CECs have potential to be carbon-neutral in relation to electricity consumption and reduce consumers’ costs with its variable term until 77%. In the future, electrification may allow CECs to be fully carbon-neutral, if they increase their flexibility portfolio.

Effects Of Land Use

This study aims to analyze the hydrological characteristics as a result of changes in land use with the help of the SWAT hydrological model and can provide recommendations on the best land use in the Koto Panjang Electric Power catchment area. Based on the results of the analysis using the SWAT hydrological model, it was seen that there were effects of land use changes in 2011 and 2014 on hydrological characteristics; yield of water (WATER YLD) of 2,413.38 mm, and 1.008, 65 mm, runoff coefficient (C) of 0.19 and 0.063 respectively, and river regime coefficient (KRS) of 11.449 and 12.212, respectively. The best land use to be developed in agricultural cultivation areas as a recommendation to maintain water stability in the Koto Panjang hydropower catchment area is a simple and complex agroforestry pattern in scenario III, which is run together with hydrological characteristics in the form; water yield (WATER YLD) of 1,038.41, surface runoff coefficient (C) of 0.023, and river regime coefficient (KRS) of 11.13. The hydrological characteristics in scenario III are far better than 2014 land use characteristics (existing).

The systematics of the dart-poison frogs, family Dendrobatidae, experienced several taxonomic rearrangements over time (e.g., Grant et al. 2006, 2017; Brown et al. 2011). Currently, this family comprises 194 described species organized in three sub-families and 15 genera (Frost 2018). Among them, the genus Adelphobates Grant, Frost, Caldwell, Gagliardo, Haddad, Kok, Means, Noonan, Schargel, & Wheeler, 2006, comprises three species, all distributed in Central and lower Amazon drainage of Peru and Brazil, and possibly in northeast of Bolivia (Grant et al. 2006; Frost 2018). Adelphobates galactonotus (Steindachner 1864) is an endemic Brazilian frog, and can be found throughout Pará, Maranhão, Mato Grosso and Tocantins states (Hoogmoed & Avila-Pires 2012), related to Amazon forest formations and also in transitional areas between the Cerrado and the Amazon forest (Valdujo et al. 2012). Despite this species is classified as Least Concern (Rodrigues et al. 2010), several threats are known. First, its geographic distribution coincides with the so-called Amazonian Deforestation Arc, which comprehends the southeastern portion of the Amazonian Forest that has been rapidly converted into pasture and crop areas or being flooded due to the construction of hydroelectric power plants (Hoogmoed & Avila-Pires 2012). Also, this species is present in Appendix II of CITES as a target for illegal trade, and their commercial exploitation should be controlled to avoid that this species become seriously endangered in the near future (see a case study in Paula et al. 2012). These threats are of deeper concern because despite A. galactonotus has been described since more than 150 years (Steindachner 1864), its tadpole remains unknown. Without a better understanding of the natural history of A. galactonotus, attempts of conservation strategies and population management are inefficient. In an effort to fill the knowledge gaps about this species natural history, we present a detailed description of the external morphology of the A. galactonotus tadpole.

All six minerals defined as “asbestos” by the existing regulation on asbestos hazard, i.e., actinolite, tremolite, anthophyllite, crocidolite and amosite amphiboles, and the serpentine-group mineral chrysotile are typical constituents of mafic and ultramafic magmatic rocks of ophiolitic sequences. However, little is known about the presence and distribution of naturally occurring asbestos (NOA) in plutonic felsic rocks. The Isadalu magmatic complex outcropping in central Sardinia and belonging to the post-variscan Permian volcanic cycle, is described here as an interesting occurrence of fibrous amphiboles in granitoid rocks. Field work and collected mineralogical/petrological data show that NOA fibers from the Isadalu complex belong compositionally to the actinolite-tremolite series. They were generated by metasomatic growth on pristine magmatic hornblende, at ca. 470 °C at 1 kbar, during sodic-calcic hydrothermal alteration. In terms of environmental hazard, the Isadalu complex represents a high-value case study, since the actinolite-bearing felsic rocks outcrop in a strongly anthropized area. Here, towns with local and regional strategic infrastructures (dams, pipes, hydroelectric power plants, water supply, roads) have been developed since the last century, also using the granitoid asbestos-rich stones. The aim of this study is to demonstrate that NOA and relative hazard are not univocally connected to a restricted typology of rocks. This result should be taken into account in any future work, procedure or regulation defining asbestos occurrences in natural environments.

Irrigation Water Allocation

The area of the Batu Bulan dam is less than 183 hectares with a capacity of 15 liters per second, the largest dam on the island of Sumbawa, located in Batu Bulan village, Moyo Hulu sub-district, Sumbawa regency, West Nusa Tenggara. Batu Bulan Dam is planned to be able to meet the irrigation needs, raw water, and has a potential for hydroelectric power plants. Considering the latter plans and the limited water supply from the dam, it is necessary to have a study for the optimization of the Dam's water allocation. By this study, the water allocation can be optimized and the planting patterns are managed. This is the objective of this research, namely the optimization of Batu Bulan Dam waters allocation for irrigation utilization, which is expected to improve dam operation patterns, to obtain the best cropping patterns and to obtain optimum benefits of rice and corn plants planted in the irrigation area. One method that can be used to solve the water allocation problem is linear programming with the objective is maximizing total profits and the constraints is water availability and land area.

<span>Hydroelectric power plants in Indonesia are widely developed. This is because the water supply in Indonesia is quite abundant. Several large reservoirs in Indonesia, in addition to being used for water reservoirs, are used to produce electricity. Wonogiri is a region that is located in Central Java province, where most of the region is arid land that cannot be planted in the dry season. In the rainy season the abundance of water plants to die and the soil is such that in the dry season crops do not grow well. Plans for the construction of Gajah Mungkur started in 1964, and it is designed to be a multipurpose dam project that aim to control floods, supply water for irrigation and hydropower in the Solo River valley. The master development plan was formulated in 1972-1974 with the help of Overseas Technical Cooperation of Japan. The results of this study include the completion of flooding problems along the Solo River, the increase in agricultural output in Winton community with irrigation facilities and good infrastructure, availability of electricity for communities around the dam and improving the local economy as the development of inland fisheries and tourism sectors.</span>

Abstract This paper proposes a new design for the shaft spillway of the Djedra dam (East Algeria). The procedure consists of replacing the circular section with a polygonal configuration of twelve (12) sections. The study of the model was divided into 5 different versions according to the variants of technical modifications of the water intake funnel; this configuration was tested on a hydraulic model in the laboratory of hydroelectric power plants of the Moscow State University of Environmental Engineering. The use of the polygonal section weir can greatly simplify the formwork of the structure, also the free entry funnel increases the discharge coefficient by 20%, without exposing the head of the weir to the risk of cavitation. In the event of submersion, the adopted design can ensure the crossing of an estimated relative flow with a probability of P = 0.01%, which means reducing the height of the dam by 0.68 m, and thus making the hydraulic structure more efficient economically and more reliable. The experimental model was produced on a 1:60 scale of the prototype, which guarantees self-simulation of the hydraulic phenomena of the Djedra dam, and its final design is judged to be hydraulically satisfactory and recommended for construction.

Hydrological Droughts

Brazil is heavily reliant on water resources. Hydroelectric plants generate about 64% of all electricity consumed. To increase yield capacity, a 2050 expansion is also planned. 78% of water used is for agriculture (irrigation and livestock), 9% for industry, and 9.1% for urban supply. However, the country has endured the worst droughts in recorded history over the last two decades, resulting in severe socioeconomic and environmental impacts. The purpose of this study was to determine the current state of knowledge regarding hydrological drought patterns, hydrometeorological factors, and their effects on the country’s hydroelectric power plants. Droughts have occurred in most of Brazil’s regions since 2014/15, causing severe impacts in many of the basins studied. Now that most hydroelectric power plants are operating at a fraction of their total capacity, the country’s hydroelectric generation is been impacted.
