Cyanobacteria Abundance and Toxin Production in a Drinking Water Supply Reservoir
… organisms that live in marine and freshwater environments and are most common during the warmer months. Many cyanobacteria are also known to release toxins that target cellular processes and affect a wide range of organisms, including people. Although the effects of toxins on …

Sediment Oxygen Demand Kinetics
… to investigate SOD kinetics in Carvin's Cove Reservoir, a eutrophic water supply reservoir for Roanoke, Virginia. A bubble-plume diffuser is used in Carvin's Cove to replenish oxygen consumed while the reservoir is thermally stratified. The applicability of zero-order, first-order, and Monod …

Development of web-based supporting tools for generic diagnostic reservoir operation
Research in the field of reservoir operation has been conducted for decades, ending with numerous numerical simulation and optimization models. However, few models are adopted in real-world applications due to enormous complexity and high computational burden requited by these models. Analytical …

Decision support system for reservoir operation using analytical modeling results
… study applies an analytical approach to solving reservoir operation problems, in particular, developing an algorithm to search for the optimal solution for a system of reservoirs in parallel, establishing procedures to determine the effective forecast horizon, and demonstrating the practical …

Some effects of the introduction of hard water into Carvin Cove Reservoir, Virginia
In November, 1966, Tinker Creek, a hard water stream was introduced into Carvin cove Reservoir, a very infertile, water-supply reservoir. This provided an excellent opportunity to study some of the interactions between fish productivity and water quality. Physicochemical conditions were monitored …

Hypolimnetic Aerators: Predicting Oxygen Transfer and Water Flow Rate
… aerators with respect to oxygen transfer and water flow rate to allow the development of two comprehensive process models. The oxygen transfer model is the first model that applies discrete-bubble principles to a hypolimnetic aerator, and the water flow rate model is the first that applies an …

Nutrient dynamics in the Lake Manassas (Virginia) watershed
Lake Manassas is a 706-acre public water supply reservoir for the City of Manassas, formed by the impoundment of Broad Run. It is located in western Prince William County at the periphery of the metropolitan Washington, D. c. area. Its watershed drains approximately 46,500 acres of rural land that …

Infrastructure investment and policy management of water resources for small-scale irrigated agriculture
… subsidies of irrigation infrastructure. Enhanced water storage and irrigation can significantly improve yield and the welfare of the farm community by providing a more reliable water supply during growing periods. Generally speaking, such enhancements require subsidies from the government or other …

Dynamic forcing of oxygen, iron, and manganese fluxes at the sediment-water interface in lakes and reservoirs
… a more interdisciplinary approach to drinking water research to address the critical issue of global drinking water supplies. Hypolimnetic oxygenation systems (HOₓ) are being increasingly used to improve water quality in stratified reservoirs by increasing dissolved oxygen (O₂) concentrations …

A Microcosm-Based Investigation into Oxidized Nitrogen Removal in the Hypolimnetic Waters of the Occoquan Reservoir of Northern Virginia
… model has been selected as a tool for use in water quality management studies of the Occoquan Reservoir. In order for the model to achieve its best possible predictive capability, additional quantitative information on denitrification rates in the reservoir was required. A microcosm operating …

Evaluating the potential of constructed groundwater systems to improve the water supply operations of Auckland City, New Zealand
A range of constructed groundwater systems are evaluated for augmenting the potable water supply of Auckland City, New Zealand. The term ‘constructed groundwater systems’ encompasses any constructed means of recharging or extracting water from an aquifer. This may for example include infiltration …
