Model predictions of biological condition for small streams in the Chesapeake Bay Watershed, USA Model predictions of biological condition for small streams in the Chesapeake Bay Watershed, USA
This data release contains predictions of stream biological condition as defined by the Chesapeake basin-wide index of biotic integrity for stream macroinvertebrates (Chessie BIBI) using Random Forest models with landscape data for small streams (≤ 200 km2 in upstream drainage) across the Chesapeake Bay Watershed (CBW). Predictions were made at eight time periods (2001, 2004, 2006, 2008...
Data for assessing the penetration depth post-1950s water in the Central Valley aquifer system, California (July 2022) Data for assessing the penetration depth post-1950s water in the Central Valley aquifer system, California (July 2022)
This dataset provides groundwater ages estimates that were used in an assessment of the penetration depth of modern groundwater in the Central Valley aquifer system (CVAL). Groundwater ages were estimated by calibration of environmental tracers (tritium, tritiogenic helium-3, chlorofluorocarbons, sulfur hexafluoride, carbon-14 and radiogenic helium-4) to lumped parameter models (LPMs)...
Geomorphic metrics across four catchments in Clarksburg, Maryland, 2002-19 Geomorphic metrics across four catchments in Clarksburg, Maryland, 2002-19
This dataset contains geomorphic metrics across 32 cross-sections at four catchments within the Clarksburg Special Protection Area in Montgomery County, Maryland. These data were derived from raw cross-sectional data collected by the Montgomery County, Maryland Department of Environmental Protection. Geomorphic metrics include channel area, bed location, channel depth, channel width, and...
Mainstem Rivers of the World based on MERIT hydrography and Natural Earth names Mainstem Rivers of the World based on MERIT hydrography and Natural Earth names
Mainstem rivers are the backbone of a connected network of hydrologic units that cover the landscape. A mainstem connects a headwater source area to an outlet. This data release identifies the same mainstem paths in hydrographic datasets for the world based on the MERIT hydrography and the Natural Earth river names. Made with Natural Earth. Free vector and raster map data @...
Data for Models Estimating Baseflow for Streams Containing Endangered Atlantic Salmon in Maine, USA Data for Models Estimating Baseflow for Streams Containing Endangered Atlantic Salmon in Maine, USA
The U.S. Geological Survey (USGS) developed a regression model for estimating August mean baseflow per square mile of drainage area to help resource managers assess relative amounts of baseflow in streams with Maine Atlantic Salmon habitat. The model was derived from August mean baseflows computed at 31 USGS streamgages in and near the Gulf of Maine Atlantic Salmon Habitat Recovery Units...
Spatial Hydro-Ecological Decision System Summarized PRISM 30-year Normal Precipitation and Temperature Data for SHEDS Region 2 Spatial Hydro-Ecological Decision System Summarized PRISM 30-year Normal Precipitation and Temperature Data for SHEDS Region 2
This data release is a summarization within the USGS Spatial Hydro-Ecological Decision System (SHEDS) framework of the Oregon State University PRISM Climate Group 30-year normal 800 meter resolution monthly, minimum and maximum temperature data and monthly precipitation data between 1991 and 2020. The output is a table consisting of the summarized values of these continuous variables for...
