Improvement of water-quality environment in reservoir models using flow networks
It is known that thermal stratification and environmental problems such as water quality deterioration occur in water reservoirs. One principle cause is the stagnation of water in the reservoirs, which leads to the problems of density stratification, nutrient enrichment of algae and others. Various methods such as deep-layer mixing and forced-air injection have been utilised to counter these ...

Coordinating multiple model predictive controllers for the management of large-scale water systems
The optimal management of multi-purpose water reservoir networks is a challenging control problem, because of the simultaneous presence of multiple objectives, the uncertainties associated with the inflow processes and the several interactions between the subsystems. For such systems, model predictive control (MPC) is an attractive control strategy that can be implemented in both centralized ...

Sarez lake, Rogun basin, Aral sea
This article analyses numerous Internet articles that discuss the use of cross-border rivers in Central Asia, including risks involving the appearance of lakes and the building of artificial water reservoirs in mountainous areas. It also evaluates options to prevent the collapse of natural dams, which created natural lakes on mountain streams, and possible ways of using the water of natural lakes ...

Soil Erosion Research - University of Zambia - Case Study
Description: A SediMeter was deployed in this water reservoir in order to collect data on the timing and amount of sedimentation in the water reservoir. Traditional methods include repeat measurements of the bed level, and taking of sediment cores, but they only allow the measurements of the net change between measurements, and are unable to register what exactly happens, and when it happens. In ...

Algae control in New Jersey raw water reservoir - Case Study
Application: Raw water reservoir, Ecuador, July 2013 Description: Installation of three LG Sonic® e-line units to cover a water surface of a 24,000-m2 raw water reservoir, which is further treated in the local drinking water plant Project objective: The raw water reservoir experienced problems with algae growth. Additionally, they settled down on the liner prior to entering the drinking ...

Reading, Pennsylvania Installations - Case Study
Mix a 15,000,000 gallon water reservoir (300’ diameter) to maintain equal temperature and chlorine residual throughout the reservoir. SPECIAL REQUIREMENTS: The system needed to be in its own all-weather outdoor enclosure. PHI SOLUTION: The system was designed with 16 bubble forming plates with their location in the tank determined by the CFD model and included two PHI-500 enclosures that ...

Time for a new water management approach in Mexico - Case Study
Ricardo Ontiveros is convinced. After being a customer using Truxor’s amphibious tool carrier he is now set to mission a new way of water management. “The regrowth in the lakes is faster than the maintenance with the current methods. With Truxor we have a possibility to change that to the better”. In the Mexican lakes and water reservoirs the invasive water hyacinth is causing ...

An Ohio City’s solution for treating algae in its drinking water treatment reservoirs - Case Study
An Ohio city used to dump tons of copper sulfate into its drinking water reservoirs to kill blue-green and green algae. Ultrasound ended this practice. Residents of Wilmington, OH, count on the water that flows from their faucets to be safe and crystal clear. But follow those pipes to the city’s two drinking water reservoirs, and the contrast is stark: blooms of harmful blue-green and ...

Impact of sulfate and chloride on sediment phosphorus release in the Yangtze Estuary Reservoir, China
The impact of sulfate (SO42−) and chloride (Cl−) on phosphorus (P) release from sediment in the drinking water reservoir of Yangtze River Estuary was studied systematically. A significant correlation between sodium (Na+), Cl−, SO42− and total P was found, suggesting that P was directly or indirectly associated with these ions. SO42− and Cl− were ...

Sampling/stochastic dynamic programming for optimal operation of multi-purpose reservoirs using artificial neural network-based ensemble streamflow predictions
Due to limited water resources and the increasing demand for agricultural products, it is significantly important to operate surface water reservoirs optimally, especially those located in arid and semi-arid regions. This paper investigates uncertainty-based optimal operation of a multi-purpose water reservoir system by using four optimization models. The models include dynamic programming ...

The influence of city water consumption on the water balance and quality of drinking water supply with implications for altered operating rules
In the period 1990–2006, the decrease in water consumption of Tallinn, the capital of Estonia, determined both the input and output of the water balance of Lake Ülemiste, the drinking water reservoir of the city as well as its hydraulic retention time (HRT). In 2006, the city's water consumption accounted for only a quarter of that in 1990.The role of regulated inflow in the water balance ...

Algal blooms in drinking water reservoirs
Frequent outbreaks of algal blooms are degrading water in drinking water reservoirs worldwide, making the water unusable. Algal blooms can sometimes be so massive that they are visible from outer space. Rising temperatures, prolonged water stagnation, extreme weather and increased runoff of nutrients from urban and agricultural lands are all compounding the algae problem. Especially in the summer ...

Spatial Analysis and Geographical Distribution of Heavy Metal Contamination in Urban House Water Reservoirs at Khamis Mushait City, Assir, Saudi Arabia
To determine the most common heavy metals in the different water reservoirs used for drinking water supply in houses located at Khamis Mushait city, Saudi Arabia (see Map1 and; (Fig.1-6, Table 1,2), Maps 2-10). To compare the results of the determined heavy metals with the standards set by Saudi Arabia Standards Organization and other international regulatory standards (Table 3). The ...
