Abstract The identification of the water level time lag (WLTL) under regulation processes is great significance for environmental impact, flood control, and sediment transport huge reservoirs. traditional hydrodynamic method can calculate inflow process change along river channel, but it difficult to estimate difference reservoir fluctuation dispatching process. To quantitatively evaluate effec...

SUMMARY Poor control of steam generator water level of a nuclear power plant may lead to frequent nuclear reactor shutdowns. These shutdowns are more common at low power where the plant exhibits strong non-minimum p...

abstractthe understanding of water resources for the purpose of ground and surface water management as two inseparable systems is great importance. in this study by examining the time series of climatic variables (precipitation), hydrological (flow and consume) and the level of water table, the parameters associated with each other and with fluctuating water table can be realized. there was a d...

In this project, we have worked with an indicator on automatic water level controller. When looked up our topic the internet, realized that most of projects used microcontrollers or IC 555, but didn’t include any these circuits in model. Our design is based LM324N IC, which functions as a rectifier, oscillator, and comparator. On foundation, construct circuit, model successfully executed at min...

Sachet water has become an important primary source of drinking water in western Africa, but little is known about bacteriologic quality and improvements to quality control given the recent, rapid evolution of this industry. This report examines basic bacteriologic indicators for 60 sachet water samples from two very low-income communities in Accra, Ghana, and explores the relationship between ...

The rheological regulation of the “three high” (high temperature, high density and high salinity) water-based drilling fluid is a worldwide problem due to the combined influence of temperature, solid content and salinity. This paper investigates the factors and regulation methods about rheological property of “three high” water based drilling fluid, and the effects of clay, salinity and weighti...
