Exploitation of hydropower potential in alpine areas undermines the ecological integrity of rivers. Damming and water abstraction substantially alter the physical habitat template of rivers, with strong repercussions on aquatic communities and their resources. Tools are needed to predict and manage the consequences of these alterations on the structure and functioning of macroinvertebrate communities and resource availability in alpine streams. We developed habitat preference models for taxa, functional feeding guilds, and organic resources to quantify the effects of discharge alteration on macroinvertebrate communities in two alpine streams. Our physical habitat model related an indirect measure of bottom hydraulic forces (FST hemispheres) to the distribution of macroinvertebrate taxa and their resources. We observed that flow-dependent habitat availability for macroinvertebrate communities generally decreased with increasing water abstraction. We were able to relate these changes to near-bed hydraulic conditions. Our results suggest, however, the existence of upper discharge thresholds delimiting optimal habitat conditions for taxa. In contrast, we found weak effects of near-bed hydraulic conditions on resource distribution. Overall, our findings contribute towards predicting the impacts of water abstraction on macroinvertebrate communities in small alpine streams and the benefits of baseflow restoration.

<p>Considering the lack of a comprehensive assessement of hydropower potential in the Upper Indus basin, we developed and implemented a systematic framework to explore four different classes of hydropower potential. Our framework uses high-resolution discharge generated by a coupled cryosphere-hydrology model as the bio-physical boundary conditions to estimate theoretical potential. Thereafter, diverse context-specific constraints are implemented stepwise to estimate the technical, economic and sustainable hydropower potential. The successive classes of hydropower potential integrate considerations for various water demands under the water-energy-food nexus, multiple geo-hazard risks, climate change, environmental protection, and socio-economic preferences. We demonstrate that the nearly two thousand Terawatt-hour of theoretical potential available annualy in the upper Indus can be misleading because a majority of this is technically and economically not viable. Even smaller potential remains if we account for the various sustainability constraints that vary spatially. Our concept of the sustainable hydropower potential enables decision makers to look beyond the energy sector when selecting hydropower projects for development to achieveenergy security under the Sustainable Development Goal 7 (SDG7).The generated portfolio of sustainable hydropower projects is superior to the current portfolio based on outdated studies because our method looks beyond theoretical possibilities and excludes projects that conflict with management objectives under other SDGs. The spatial maps with potential and the cost curves for hydropower production provide a science-based knowledge base for hydropower development in the Indus basin. Our method could similarly be adapted to inform hydropower development in other basins across the globe.</p>

The Continental intercalary groundwater is highly sought for its water as resources hugely mobilized in Northern Sahara. A very high flow rate and output pressure characterizes this underground water. It amounts from 50 to 400 l.s-1 for the flow, and from 5 to 40 bar for pressure. A survey of the Northern Sahara Aquifer System was essential to prove the existence of this potential. This energy appears into the artesian form, which remains very considerable for a very long time in most drilling. We have realised that this energy is immense, as well as the expanded volume of the groundwater, and the importance of its use in agriculture. Unfortunately, this potential remains untapped to this day and the energy of this water is completely neglected. Several turbo generator and/or inverted pump (PATs) integration tests were undergone. The new concept of reflection with respect to the environment and sustainable development has led us to structure our work towards the extension of this potential in order to extract the exploitable energy.

This paper proposes hydropower potential sites for several islands located in the South China Sea. The islands depend mainly on diesel-fuel for electricity generation. As a result, the generating company exposed to diesel high and unpredictable market prices, high operation and maintenance costs, and possible risk of fuel spills. Therefore, reconnaissance studies were conducted through topographic maps and hydrological studies in order to determine the potential sites suitable for development of micro-hydro and pico-hydro generation. The studies conducted for 14 islands in the South China Sea with a total of 51 investigated sites. The result indicates that 24 sites identified to have micro-hydro potential and 22 sites have pico-hydro potential.

The potential of Greenland hydropower came into focus folIowing the energy crisis in 1973 and the subsequent demand for exploitation of Greenland's own energy resources. Investigations have been made since the mid-1970s on the feasibility of hydropower in Greenland. At first, emphasis was put upon large, or regional, basins that could supply new energy-intensive industries (GTO, 1975). During the 1980s, the emphasis changed to the so-called 'town basins' where hydropower would be developed to supplement the existing energy in selected Greenland towns. The first hydropower plant is under construction at the Kangerluarsunnguaq/Buksefjorden basin south-east of Nuuk, the capital of Greenland, to supply Nuuk with energy (Fig. 1). This hydropower plant is planned to come into operation in autumn 1993.

Abstract This article analyzes the hydropower potential of watercourses in Slovakia, defining water as the most promising and most used renewable energy source. The hydro-energetic potential as a source of energy is determined by the calculation of the technically feasible potential of the watercourses, which is divided into exploited and unused. It also identifies the potential of utilizing the unused technical hydro-energetic potential.
