Geospatial Applications

The USGS is the Nation’s largest Earth science civilian mapping agency, mapping in the United States and abroad for more than 125 years and changing products and services offered and the means by which they are developed to meet changing expectations of users, new understandings of societal and mission needs, and new technologies. The NYWSC uses the latest available spatial datasets to provide geospatial expertise for scientific investigations; geographic information systems (GISs) are used to characterize the natural and manmade features that define the environmental settings of drainage basins and groundwater study areas. As the quality and resolution of remotely sensed geospatial data and imagery continues to improve, GISs can be used to visualize and explore these data. For example, light detection and ranging (lidar) elevation data can be displayed with hill-shade and color classifications that provide far greater detail than 1:24,000-scale topographic maps.

Comprehensive Delineation of Groundwater Source Areas and Times-of-travel to Long Island Streams and Estuaries

Problem The discharge of freshwater and associated loading of nutrients and other dissolved constituents from the Long Island aquifer system to surrounding estuaries and their tributaries are increasingly recognized as critical factors in the health of these ecosystems. However, further work is needed to scientifically characterize these factors and present them to the public in an...

Geohydrology of the Upper Sixmile Creek/West Branch Owego Creek Valleys and Lower Sixmile Creek/Willseyville Creek Valleys, Town of Caroline, Tompkins County, New York

Problem - The Town of Caroline needs geohydrologic data in two major valley-fill aquifers within the town in order for planners to develop a strategy to manage and protect their water resources. Interest in the interaction between ground water and surface water has increased in recent years as a result of widespread concerns related to water supply. The need to better understand how the...

Statewide Assessment of New York’s Karst Aquifers With an Inventory of Closed-Depression and Focused-Recharge Features

Background: The New York State Departments of Environmental Conservation (NYS DEC) and Health (NYS DOH) are concerned about groundwater contamination in the carbonate-bedrock aquifers in New York, especially relating to the unintended introduction of volatile organic compounds (VOCs) and liquid manure to these aquifers. These carbonate rocks form extensive aquifers that transmit, and can yield...

Hydrogeologic Recharge Settings of the Carbonate-Bedrock Aquifers in Livingston and Monroe Counties, Western New York

Background: A sequence of gently dipping carbonate bedrock - the Bertie Formation, Akron Dolostone, and Onondaga Limestone crop out along a 2- to5-mile wide band in western and central New York. These bedrock units trend east-west for 250 miles across the State and form extensive carbonate-bedrock aquifers which transmit and yield water from solution-enlarged fractures, bedding planes, and...

Flood-inundation mapping of Egypt Creek, Dryden, Tompkins County

Problem – Flooding is an annual problem along Egypt Creek in Dryden. Increased runoff from expanding development, sediment clogged channels, and undersized culverts that cannot convey increased flows contribute to the problem. Flood maps for extreme floods are available through the effective FEMA flood insurance study (FEMA, 1978), but these maps, which became effective in 1979, are considered...

New York Nowcast, Recreational Beaches of New York

Problem – Currently, swim advisories or closings are issued by beach managers based on standards for concentrations of bacterial indicators such as Escherichia coli (E. coli). Standard culture methods for these bacteria take at least 18-24 hours before results are available. At most Great Lakes beaches, the beach is posted with an advisory or closing or is determined to be acceptable for...

Development of a Graphical User Interface (GUI) to Predict Streamflow Statistics using USGS Streamstats and Precipitation from Downscaled Global Climate Change Models

Background Climate change during the past century has resulted in changes to precipitation amounts, form (rain vs. snow), as well as frequency and intensity in the northeastern US (Huntington et al., 2009). Additional changes in precipitation are forecast for the 21st Century as the global and regional climate is expected to warm substantially (Hayhoe et al., 2007). These ongoing and proje...

Detailed Aquifer Mapping in Eastern Broome and Southeastern Chenango Counties, New York

Introduction Detailed mapping of stratified glacial deposits in eastern Broome and southeastern Chenango Counties, New York is a study in the cooperative Detailed Aquifer Mapping Program between the US Geological Survey (USGS) and the New York State Department of Environmental Conservation (NYSDEC). The aim of the program is to map glacial aquifers in New York State at a scale of 1:24,000...

State of the Aquifer, Long Island, New York

Background In recent years, more and more people have become concerned about Long Island's supply of freshwater. Currently, there is no comprehensive, island-wide resource that summarizes recent U.S. Geological Survey (USGS) research related to the Island's aquifer system. A webpage will be developed by the USGS that will compile published data from the hydrologic-surveillance program, in p...

Bathymetry of New York City's West of Hudson Reservoirs

Background Every day, the New York City Department of Environmental Protection (DEP) supplies more than one billion gallons of drinking water to more than nine million people. To do this, the DEP maintains an extensive network of reservoirs and aqueducts. A major part of this system, the West of Hudson (WOH) network, in the Delaware and Hudson River drainages, includes six reservoirs (fig. 1...

Flood-Inundation Maps for the Schoharie Creek at Prattsville, New York

Background and Problem Prattsville has experienced severe flooding along the Schoharie Creek, most notably during August 2011 following Hurricane Irene, which severely damaged or destroyed large areas of the town, and caused several million dollars in damages (Figure 1). Before and during a flood, forewarning and emergency response are critical. The rescue efforts of emergency responders are...
