MD-DE-DC Groundwater Capabilities

Always start with dependable, reliable data

See the Groundwater Capabilities site here

Hydrologic data collection, processing, analysis, dissemination, and archiving are major parts of the MD-DE-DC Water Science Center program. Much of the data are available on a near-real-time basis by satellite telemetry.

The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols.

Dam impact/disturbance metrics for the conterminous United States, 1800 to 2018 Dam impact/disturbance metrics for the conterminous United States, 1800 to 2018

This metadata record describes two metrics that quantitatively measure the impact of reservoir storage on every flowline in the NHDPlus version 2 data suite (NHDPlusV2) for the conterminous United States. These metrics are computed for every 10 years from 1800 - 2015. The first metric (DamIndex_EROM.zip) estimates reservoir storage intensity in units of days based on reservoir storage in...

Contiguous U.S. annual snow persistence and trends from 2001-2020 Contiguous U.S. annual snow persistence and trends from 2001-2020

Snow persistence (SP) or the snow cover index (SCI), is the fraction of time that snow is present on the ground for a defined period. Cloud covered index (CCI) is the fraction of time that there is no data, cloud, or sensor saturation for the same period. SP and CCI were calculated on a pixel by pixel basis using MODIS/Terra Snow Cover 8-Day L3 Global 500m Grid, Collection 6 obtained...
