Map of Surficial Aquifer Potential in Connecticut

The Connecticut Geological Survey's (CGS) map of surficial aquifer potential shows the areas with high potential for groundwater supply based on the thickness of coarse-grained deposits. Colors on the map indicate the thickness of coarse-grained deposits and the thickness of fine-grained deposits where they occur over coarse-grained sediments.

EARTH: Travertine Buildup Reflects Ancient Rome's Water Usage

For years historians and scientists have tried to understand the ancient marvel of the Roman aqueducts to better understand Rome itself. Now archaeologists are using a new method - the buildup of travertine within the Anio Novus aqueduct - to determine how much water flowed into Rome.

EARTH: Declining U.S. Water Use a Challenge For Models

Water demand in communities nationwide is decreasing due to better efficiency and more effective conservation programs, but also due to demographic shifts that may require a rethink in the way that water usage is modeled.

Interactive map of the U.S. energy sector's vulnerabilities to climatic conditions

The U.S. Department of Energy's interactive map of the energy sector's climatic vulnerabilities allows users to explore how climatic events have impacted the energy sector over recent years. You can view how impacts due to increasing temperatures, decreased water availability, and increasing storms, floods, and sea level rise have adversely affected energy resource development, distribution, production, and transmission.

Visualization of drought in California

The U.S. Geological Survey provides a website of visualizations that show how California's extreme drought in the early-mid 2010s progressed through the early-mid part of the decade and then was relieved with significant rain and snowfall in 2016-2017. Visualizations of the extent and severity of drought, change in reservoir volumes, and streamflow compared to historic rates are all available on the website, which you scroll through to see different features.

Water as One Resource: How interactions between groundwater and surface water impact water availability

Monday, July 13, 2015

Overarching questions addressed in this webinar include:

How do surface water and ground water interact and what implications do these interactions have for sustainable water management?
Are there new tools/resources/partnerships that can be used to better manage surface water and groundwater as connected resources?
What policy limitations exist for managing water as one resource?
Are there best practices that water management organizations can implement?

Our speakers include:

Ken Bradbury, Wisconsin Geological and Natural History Survey | Slides Video
William M. Alley, National Ground Water Association | Slides Video
Thomas Harter, University of California, Davis | Slides Video

Webinar Co-Sponsors:
National Ground Water Association, Wisconsin Geological & Natural History Survey, Association of American State Geologists

Map of groundwater depletion in the United States

The U.S. Geological Survey's (USGS) map of groundwater depletion shows the cumulative depletion of groundwater for 40 aquifer systems across the U.S (excluding Alaska). The map depicts depletion over the time period of 1900 to 2008 and is measured in cubic kilometers.

Interactive map of groundwater levels in Maryland

The Maryland Geological Survey, in cooperation with the U.S. Geological Survey, maintains a state-wide network of groundwater observation wells. The data from these wells is used to create an interactive map of groundwater levels in Maryland. The map provides both historical and recent groundwater reading levels across a range of aquifers in the state of Maryland.
