Behind the gate - International Water Power
Dec 10, 2008 · The first, and most commonly used, is an overflow type. This gate is designed for 1ft (0.3m) of water flowing over the top of the gate when the gate is closed. Adequate safety factors prevent damage to the gate if there is a moderate, additional overflow beyond that limit for a short period of time, says the company.
A world first for Clyde Dam - International Water Power
Nov 25, 2021 · The Clyde Dam. The Clyde Dam is the largest concrete dam in New Zealand and was constructed in the 1980s to a design PGA of 0.54g (Officers of the New Zealand Geological Survey, 1983). It is responsible for about 6% of New Zealand’s power generation. Construction of the dam was not without major challenges, namely:
Concrete solutions: strengthening America’s dams
Oct 11, 2023 · S&T chose to work on this effort because water poses very challenging and complex situations for concrete. What works for aging water infrastructure like dams and levees, most likely would work for dry-land concrete-based infrastructure like bridges and buildings. This initial use case could become the catalyst for an entire research agenda.
Pumped storage: powering a sustainable future
Nov 21, 2023 · Pumped storage provides a ‘load’ when the wind is blowing and the sun is shining, and it also provides a reliable and immediate source of dispatchable energy when the available renewable generation can’t meet demand. By pumping the water uphill when generation exceeds demand, the pumped storage scheme is essentially ‘storing’ energy ...
Hydro development in Uzbekistan - International Water Power
Oct 1, 2019 · The studied hydropower potential of Uzbekistan is estimated at 27.5 billion kWh per year, but currently, only approximately 30% of this potential has been utilized. This potential was actually estimated approximately 30 years ago, and today’s figure is likely to be increased taking into account new potential sites studied in recent years and ...
