  • How to plan hydropower stations for the future

    The hydropower plants of tomorrow won’t only produce energy. Constructing dams will also provide new drinking water sources, irrigation for crops, and new waterways for transport. In the words of most of the scientists here at World Water Week in Stockholm, Sweden, they will be ‘multipurpose’. This means that each plant ...

  • Limited adaptive genetic algorithm for inner-plant economical operation of hydropower station

    A limited adaptive genetic algorithm (LAGA) is proposed in the paper for inner-plant economical operation of a hydropower station. In the LAGA, limited solution strategy, with the feasible solution generation method for generating an initial population and the limited perturbation mutation operator, is presented to avoid hydro units operating in cavitation–vibration regions. The adaptive ...

  • Control systems for small hydropower plants: a review

    Hydropower is emerging as a major contributor to world energy requirement. It is inexhaustible, clean and has many other benefits like flood mitigation, water supply, irrigation, etc. However, large-scale hydropower generation suffers from inherent disadvantages, such as massive financial outlays, long gestation periods, geological surprises, environmental factors and rehabilitation of the ...

  • Evaluation of precipitation forecasts from NOAA global forecast system in hydropower operation

    Forecasts of 10-day average inflow into the Ertan hydropower station of the Yalong river basin are needed for seasonal hydropower operation. Medium-range inflow forecasts have usually been obtained by Auto-Regressive-Moving-Average (ARMA) models, which do not utilize any precipitation forecasts. This paper presents a simple GFS-QPFs-based rainfall - runoff model (GRR) using the 10-day accumulated ...

  • SHP stations and integrated rural development: a multivariate statistical approach

    The multi-functional role of the rural space is gradually being enhanced in recent decades, as agriculture seems to be losing its leading position. The diversification of local economies through the exploitation of natural resources is being highlighted as a fundamental driving force for development. Renewable Energy Resources (RES) and, more specifically, the establishment of Small Hydropower ...

  • Reservoir optimization model incorporating inflow forecasts with various lead times as hydrologic state variables

    This paper presents two Stochastic Dynamic Programming models (SDP) to investigate the potential value of inflow forecasts with various lead times in hydropower generation. The proposed SDP frameworks generate hydropower operating policies for the Ertan hydropower station, China. The objective function maximizes the total hydropower generation with the firm capacity committed for the system. The ...

  • Analysis of Development Course of Artificial Sand Making Technique

    In the artificial sand and stone material production system, the sand making technology is one of the most important technologies, and the sand making equipment is the most equipment because the performance of the sand maker and the reasonability of the sand making technology influence the investment of the whole artificial sand and stone material processing system and the quality of the ...

  • Impacts of Danjiangkou reservoir on sediment regime of the Hanjiang River

    With population increase and economic growth, the development of water resources and hydropower resources of the Hanjiang River has been intensified by dam building, and consequently the sediment regime of the Hanjiang River has been altered to some extent. To assess dam-induced alterations in the sediment regime of the Hanjiang River quantitatively, we selected three key hydrological stations ...

  • Stochastic simulation for determining the design flood of cascade reservoir systems

    Stochastic simulation is widely applied for estimating the design flood of various hydrosystems. The design flood at a reservoir site should consider the impact of upstream reservoirs, along with any development of hydropower. This paper investigates and applies a stochastic simulation approach for determining the design flood of a complex cascade of reservoirs in the Longtan watershed, southern ...

  • A systems approach for collaborative decision support in water resources planning

    This paper presents a systems approach for collaborative group planning of water development projects. Two dynamic modelling paradigms were considered for development of a collaborative planning support system (CPSS). One paradigm is based on negative feedback, which forces system transformation towards an external goal. The selected paradigm is based on the concept of positive feedback. Positive ...

  • A model for the snow water equivalent derived from stratigraphy observations in northern Sweden

    A new parameterization of snow water equivalent (SWE) based on snow depth (HS) has been developed from observations made in northern Sweden. When applying previous SWE parameterization from the Alps on observations from northern Sweden, the SWE values are systematically 20% lower. The new SWE parameterization is derived from a snow layer density regression model using snow layer hardness and ...

    The Systems Conveyance and Operations Program (SCOP), located in Clark County, Nevada, will enable the Clean Water Coalition (CWC) to improve the water quality of Lake Mead, the main water source for the Las Vegas Valley, and to meet the increasing water demands of its four member agencies: the City of Las Vegas (CLV), the Clark County Water Reclamation District (CCWRD), the City of Henderson ...

  • Mount Kenya biosphere reserve

    Mount Kenya rises to 5199 m. a.s.l. and thus a major landmark. The mountain is a Pleistocene composite dormant volcano. It is a major water-tower that serves lowland inhabitants up to the Indian Ocean. It was protected as National Park in 1949 and in 1978, its summit and the Park became a BR and a World Heritage Site in 1999. Its main virtues include a rich biodiversity and the only glacial ...

  • Mission: Saving the Okavango Delta

    One of the world's few inland deltas, the Okavango, is facing pressure on several fronts. Three states with differing needs must cooperate to save it for future generations. Botswana has in recent decades often been [spoken of as an African success story. Stable, reliable and wealthy. Soon after independence in 1966, diamonds were discovered under its desert sands, and consecutive ...

  • Where Has All the Ice Gone?

    As the earth warms, glaciers and ice sheets are melting and seas are rising. Over the last century, the global average sea level rose by 17 centimeters (7 inches). This century, as waters warm and ice continues to melt, seas are projected to rise nearly 2 meters (6 feet), inundating coastal cities worldwide, such as New York, London, and Cairo. Melting sea ice, ice sheets, and mountain glaciers ...

  • Cleantech Trends that will Change Our Future

    The terms ‘ground-breaking’ or ‘game-changing’ are frequently used to describe a new technology, or to market an innovation that supposedly will change our world forever. The truth is, we seldom really know how a new technology will unfold and how, over time, it will become part of our daily lives. The personal computer, digital imaging, genetic engineering, and the ...
