Small hydropower (SHP) facilities, which are defined by installed capacities 20% net retention of suspended sediments, two others retained between 10 and 20%, seven were within 10%, and six showed >10% net release. Bedload sediment transport was a small component of total sediment transport in rivers with high total sediment loads. Multiyear series...
Diplomová práce se zabývá koncepcí výměny uzavíracích klapek na vodní elektrárně Nedre Vinstra v Norsku. Práce je rozdělena na teoretickou a praktickou část. Teoretická část popisuje stávající stav na vodní elektrárně a specifikuje problémy vycházející z provozu uzavíracích klapek umístěných za vyrovnávací komorou. Praktická část má za cíl vytvořen...
The aim of this study is to analyse the voltage regulation of a power grid when wind power parks are connected to an existing power grid. Secondary the project have studied the placement of these wind power parks and costs related to connecting them to the grid. The goal was to achieve this grid with a smaller than 5% voltage margin and preferably ...
ABSTRACT We investigated whether the movement and distribution of the migratory fish, Salminus brasiliensis, were affected by a small reservoir. We also examined how movement and distribution were related to water temperature, flow, and rainfall. In December 2011 and January 2012, 24 individuals were captured downstream from the dam, tagged with ra...
The Grand Ethiopian Renaissance Dam (GERD) is a large hydropower project currently under construction in Ethiopia. Supposedly it will benefit the people of Ethiopia through an increased access to electricity, but it is also associated with complex political relations between Ethiopia and the neighbouring countries Egypt and Sudan. The aim of this t...

Dieser Beitrag zeigt die Bedeutung der alpinen und im Speziellen auch der österreichischen Wasserkraft. Im Rahmen einer im Jahr 2016 von der Arbeitsgemeinschaft Alpine Wasserkraft (AGAW) bei VUM Verfahren Umwelt Management GmbH beauftragten Studie „Status und Zukunft der alpinen Wasserkraft“ wurde auf Einzelkraftwerk-Ebene eine Erhebung im gesamten...
L’aspirateur d’une centrale hydroélectrique est l’organe hydraulique se situant en aval de la roue. Il a une forme divergente afin de récupérer l’énergie cinétique résiduelle en sortie de roue sous forme de pression statique et augmenter ainsi la chute nette de la centrale. Dans le cas des turbines de basse chute de type bulbe, les pertes de charge...
Energy and water resources systems are tightly coupled; energy is needed to deliver water and water is needed to extract or produce energy. Growing pressure on these resources has raised concerns about their long-term management and highlights the need to develop integrated solutions. A method for joint optimization of water and electric power syst...
