Planning of Hydraulic Flushing Schedule for Prolonging the Life of a Hydropower Plant
Iranian Journal of Science and Technology, Transactions of Civil Engineering, 2018This paper presents a sediment management study through hydraulic flushing of a reservoir at a hydropower station in Kashmir, Pakistan. The study area is under the influence of monsoon rains and is part of a seismically active region along the northwestern zone of Eurasian plates.

Turbulent flushing of internal pipe-type surfaces in hydraulic components
Proceedings of the Institution of Mechanical Engineers, Part E: Journal of Process Mechanical EngineeringThe cleanliness of hydraulic systems has long been regarded as a crucial indicator of their performance and longevity. This study aims to elevate the cleanliness level of hydraulic components from 500 μm to 300 μm. To achieve this goal, this study integrates the flushing process and establishes a physical and mathematical model of wired solid ...

Hydraulic flushing as a Prymnesium parvum bloom-terminating mechanism in a subtropical lake
Harmful Algae, 2010Prymnesium parvum blooms have increased in frequency and magnitude in the south-central USA in recent years, resulting in large fish kills and economic losses. Here, we document seasonal and system-wide plankton dynamics of Lake Granbury, TX, over a period spanning the formation and termination of a large, highly toxic, P.

Analytical estimates of hydraulic parameters for an urbanized estuary – Flushing Bay
Journal of Hydrology, 2007Summary Prediction of water quality improvements in urban estuaries is an urgent priority for decision making about alternative mitigation measures, especially in the context of changing pollutant loadings and freshwater discharges. Flushing Bay, an embayment of the New York–New Jersey Harbor Estuary, is a “short” estuary (a special class of coastal ...

Suitability of degraded peat for constructed wetlands — Hydraulic properties and nutrient flushing
Geoderma, 2014Abstract Nitrate removal from runoff from agricultural land is in general required to reach a “good chemical status” of surface and groundwater bodies according to the European Water Framework Directive. Removing nitrates via heterotrophic denitrification is highly effective but requires stable anoxic environmental conditions as well as available ...

Nutrient retention and transformation in relation to hydraulic flushing rate in a small impoundment
Freshwater Biology, 1983SUMMARY. The fluxes of water, chloride, silicale and various forms of nitrogen and phosphorus into and out of a 3925 ha impoundment (Lake Taiquin) in north Florida were examined over a 3 year period. Annual hydraulic flushing rates for the lake varied by a factor of more than 2 during the study period and provided an opportunity to examine the effect ...

Hydraulic evaluation of the proposed Brandon Road Lock flushing system
The Great Lakes Mississippi River Interbasin Study is a US Army Corps of Engineers effort focused on stopping the migration of aquatic nuisance species (ANS) from the Mississippi River to the Great Lakes. Brandon Road Lock and Dam (BRLD) has been chosen as the location to stop this northward migration.E. Hammack +5 more

Biological and hydraulic monitoring of sediment flushing from an alpine reservoir
2007The first results of the biological and hydraulic monitoring programme carried out during the sediment flushing of an Alpine Italian reservoir are presented. The flushing and the monitoring activities were planned and executed by several private and public subjects, including the hydroelectric company in charge of the reservoir management (AEM S.p.A.),

Experimental study and modelling of the hydraulic behaviour of a Hydrass flushing gate
2004As well known, a periodical cleansing of sewers results necessary in order to avoid or reduce many unpleasant consequences due to the presence of sediments, such as the solid re-suspension during rain events and the reduction of the sewer flow capacity. For this purpose, different systems based on flushing techniques have been adopted in sewers. In the
