Ground water reservoir response to earth tides
… for the computation of poresity from tidal water level measurement is presented. Tidal water level fluctuations in three artesian wells of southwest Virginia were recorded, digitized and harmonically analysed. Corrections for non tidal water level fluctuations and barometric pressure effects …

Internal Cycling in an Urban Drinking Water Reservoir
… (P) and metal cycling in the Eagle Creek Reservoir (ECR), located in Indianapolis, central Indiana. Eagle Creek Reservoir serves the drinking water needs of over 80,000 residents. Within the last several years, algal blooms have created stress to the local treatment facility. The objective …

Metal fluxes across the sediment water interface in a drinking water reservoir
… of iron (Fe) and manganese (Mn) in drinking water degrade water quality by affecting taste, odor, and color. Under oxic conditions (dissolved oxygen (DO) >2 mg/L), Fe and Mn are rarely present in soluble form in natural waters, as they occur as insoluble, oxidized minerals in sediments. …

Reproduction and Diet of Pseudemys Concinna Inhabiting a Cold Water Reservoir in Southwest Missouri
River cooters, Pseudemys concinna, were colleced using fyke nets from two locations, one hypothermic cove (Rockaway Slough) and one normothermic cove (Bull Creek) at Lake Taneycomo, from April 1993 to August 1994. Quantitative and qualitative analyses of adult diets from both sites showed great …

Reproduction and Diet of Kinosternon Odoratum Inhabiting a Cold Water Reservoir in Southwest Missouri
Kinosternon odoratum were collected from two habitats on Lake Taneycomo, a hypothermic cove (Rockaway Slough) and a normothermic cove (Bull Creek), from April 1993 through August 1994. Dietary analysis showed a significant difference between sites in the frequency of food items taken. There were no …

Insect-Induced Forest Disturbance Impacts on Select Water Quality Parameters in a Closed Drinking Water Reservoir
… precipitation and river inflows impact drinking water reservoirs. Natural organic matter (NOM) directly impacts water treatment process effectiveness and is identified as an emerging contaminant of concern. Few studies have examined how insect-induced forest disturbance contributes to abiotic …

Exploring subsurface ground water and geochemical rock interactions during drainage of a surface water reservoir in Switzerland
… the spatial and temporal controls on groundwater chemistry in a fractured granitic environment. The research was conducted at the Grimsel Test Site, Switzerland (GTS), where draining and refilling of a nearby surface water reservoir induced microseismicity In the surrounding rocks. The GTS …

The effects of hypolimnetic oxygenation on the chemical, physical, and biological properties of a shallow drinking water reservoir
… phosphorus (P) loads from the sediments to the water column, thereby increasing nutrient availability, making preventing anoxia a major goal for lake managers to improve water quality. Side-stream saturation (SSS), a type of hypolimnetic oxygenation system, has been developed to maintain …

High-frequency sensor data capture short-term variability in Fe and Mn cycling due to hypolimnetic oxygenation and seasonal dynamics in a drinking water reservoir
… of iron (Fe) and manganese (Mn) in lakes and reservoirs have predictable seasonal trends, largely governed by stratification dynamics and redox conditions in the hypolimnion. However, short-term (i.e., sub-weekly) trends in Fe and Mn cycling are less well-understood, as most monitoring efforts …

Characterizing the dam break release
… wave velocity was found to increase as the water reservoir height was increased. An equation was derived that had a 0.96 correlation coefficient thus proving that the relationship between velocity and reservoir height was accurate. Further research can be done using a cantilevered plate …

Maturation and Reproduction of the White Sucker (Catostomus Commersoni) in Lake Taneycomo, Missouri
… of white suckers in Lake Taneycomo, a cold water reservoir, lasted from early April to late May in 1994 and 1995. Evidence suggested that spawning took place in all tributaries of the lake but not in the lake itself. White suckers begain to mature at age 3 and at a length of 275 mm. Males …

Hypolimnetic Oxygenation Mitigates the Effects of Nutrient Loading on Water Quality in a Eutrophic Reservoir
… predicted to have many diverse effects on freshwater lakes and reservoirs by increasing both hypolimnetic hypoxia and runoff, which will increase nutrient concentrations and degrade water quality. Hypoxic conditions can trigger the release of metals and nutrients from the sediments, i.e., …
