plumeria PMAP software release 1.0.3 plumeria PMAP software release 1.0.3
The PMAP tool is a one-dimensional plume model that predicts ash aggregation within an erupting volcanic plume. The tool was developed by D. W. Hoffman at Stanford, extending from the Plumeria model written by L. G. Mastin at USGS CVO. The code operates using Matlab. The purpose of this repository is to present the code used in the following publication, currently under review at Journal...
Calculated baseflow recession characteristics for streamflow gauging locations for the western and eastern United States, 1900 to 2018 Calculated baseflow recession characteristics for streamflow gauging locations for the western and eastern United States, 1900 to 2018
This metadata record describes observed and predicted baseflow recession characteristics for 300 streamflow gauges in the western United States and 282 streamflow gauges in the eastern United States. Specifically, this record describes (1) the streamflow gauge locations (west or east) in the United States (Location), (2) the U.S. Geological Survey streamflow gauge identification numbers...
Lake Ontario April Prey Fish Bottom Trawl Survey, 1978-2022 Lake Ontario April Prey Fish Bottom Trawl Survey, 1978-2022
This data release includes Lake Ontario prey fish data including species captured, relative abundance, spatial distribution, size structure, and age data from the April or spring prey fish bottom trawl survey, 1978 through 2022. Data from 1978 - 2015 are from U.S. waters of Lake Ontario while data from 2016 - 2022 include both U.S. and Canadian waters of Lake Ontario. Details about the...
Concentrations of metals and other water quality data for the Assabet and Concord Rivers, Massachusetts, 2008 Concentrations of metals and other water quality data for the Assabet and Concord Rivers, Massachusetts, 2008
This dataset contains water-quality data for stream samples collected by the U.S. Geological Survey at 12 sites on the Assabet and Concord Rivers in eastern Massachusetts in 2008. The samples were collected monthly from June to October, 2008. The water-quality parameters and constituents include field parameters (water temperature, specific conductance, pH, and dissolved oxygen)...
SPARROW Model Inputs and Estimated Effects of Agricultural Conservation Practices on Total Nitrogen in Streams of the Chesapeake Bay Watershed SPARROW Model Inputs and Estimated Effects of Agricultural Conservation Practices on Total Nitrogen in Streams of the Chesapeake Bay Watershed
This data release contains input and output data tables from a SPAtially Referenced Regression On Watershed attributes (SPARROW) model, which estimated total nitrogen loads in streams of the Chesapeake Bay watershed under varying better management practice implementation scenarios. Further documentation about the SPARROW modeling framework can be found here: https://pubs.er.usgs.gov...
MODFLOW6 models used to evaluate potential stresses and hydrologic conditions driving water-level fluctuations in well ER-5-3-2, Frenchman Flat, Southern Nevada MODFLOW6 models used to evaluate potential stresses and hydrologic conditions driving water-level fluctuations in well ER-5-3-2, Frenchman Flat, Southern Nevada
The hydrograph for well ER-5-3-2 in Frenchman Flat, southern Nevada, has previously unexplained water-level fluctuations. Four, three-dimensional, groundwater models (MODFLOW 6) were developed to evaluate potential stresses and hydrologic conditions affecting the well ER-5-3-2 hydrograph. Four model scenarios were developed that simulated: (1) wellbore leakage without recharge, (2)...
