Water Use in New York

Problem - The demand for water in New York State is unevenly distributed. Because increasing competition for local supplies could lead to shortages, it is expedient to know how and where water is withdrawn, delivered, and used. There are many dimensions to water-use issues, and all should be considered to develop a full understanding of the use and delivery of water in the State. In order t...

Continuous and Spatially Distributed Dissolved Oxygen Monitoring in Long Island Estuaries in Support of Coastal Resource Management.

Problem Dissolved oxygen (DO) is an important indicator of water quality that until recently has been cost-prohibitive to monitor extensively in both space and time. Continuous water-quality data, particularly in coastal environments with bidirectional tidal flow, is necessary for resource managers to understand the dynamic changes in water quality that occur tidally, daily, seasonally, and...

Detection and Quantification of Oxygenated Polycyclic Aromatic Hydrocarbons (oxy-PAHs) in Groundwater Near the Former Manufactured Gas Plant in Bay Shore, N.Y.

Introduction As a result of storage and disposal practices at a former Manufactured Gas Plant, or MGP, in Bay Shore, NY, a variety of polycyclic aromatic hydrocarbons (PAHs) have been detected at high concentrations in the surficial, upper glacial aquifer of Long Island. Levels of PAHs initially detected over 10 years ago were in the parts-per-thousand range within a groundwater contaminant...

Simulation of Streamflow and Water Quality by a Precipitation-Runoff Model of the Tonawanda Creek Basin in Western New York

Problem Nutrients and sediment are generated by and removed from agricultural and urban areas, transported in streams, and ultimately delivered to the Great Lakes. The nutrients stimulate excessive algal growth and potentially cause noxious blooms and hypoxia. Sediment increases turbidity near stream mouths and, when deposited, can smother bottom-dwelling animals, drive fish from affected a...

Changes in Soil and Stream Water Chemistry in Response to Reduction in Acid Deposition in the Catskills

Summary The Environmental Protection Agency’s (EPA) Long Term Monitoring (LTM) network has supported the collection of stream chemistry data in the Catskills since the 1990s. Trends in stream chemistry have periodically been evaluated in these streams but the most recent assessments only extend through the early 2000s. An updated assessment of stream chemistry trends will help evaluate the...

Technical Pump-Test Evaluation of Suffolk County Aquifers

Problem - USGS regional framework characterizations have been used effectively in many studies. However, lack of framework accuracy, particularly at smaller scales, continues to cause problems that may involve: (1) sizing of pumps and other aspects of wellfield design and maintenance, (2) projection of local-scale water-level changes, and (3) projection of interactions with other hydrologic...

A consistent global approach for the morphometric characterization of subaqueous landslides

Landslides are common in aquatic settings worldwide, from lakes and coastal environments to the deep sea. Fast-moving, large-volume landslides can potentially trigger destructive tsunamis. Landslides damage and disrupt global communication links and other critical marine infrastructure. Landslide deposits act as foci for localized, but important,...

Downstream fish passage guide walls: A hydraulic scale model analysis

Partial-depth guide walls are used to improve passage efficiency and reduce the delay of out-migrating anadromous fish species by guiding fish to a bypass route (i.e. weir, pipe, sluice gate) that circumvents the turbine intakes, where survival is usually lower. Evaluation and monitoring studies, however, indicate a high propensity for some fish...
