MODFLOW 6 models for simulating groundwater flow in the Mississippi Embayment with a focus on the Mississippi Delta This model archive contains the model files for the MERAS 3 and Mississippi Delta groundwater flow models documented in the U.S. Geological Survey Scientific Investigations Report 2023-xxxx. The MERAS 3 model provides a simplified representation of groundwater flow in the Mississippi Embayment Regional Aquifer Study (MERAS) area for the period of 1900 through 2018, with the primary goal of providing boundary fluxes for inset models focused on local areas of interest. The Mississippi Delta model simulates groundwater flow in the Delta region of northwestern Mississippi from 1900 through 2018, using boundary fluxes from the MERAS 3 model. A scenario version of the Mississippi Delta model extends the simulation to...

They are being provided to meet the need for timely best science. The data have not received final approval by the U.S. Geological Survey (USGS) and are provided on the condition that neither the USGS nor the U.S. Government shall be held liable for any damages resulting from the authorized or unauthorized use of the data. The Interagency Grizzly Bear Study Team (IGBST) evaluates mortalities for population segments within the DMA by deriving estimates of total mortality for independent-age (2 years or older) females and independent-age males, including estimates of unknown/unreported mortalities based on Cherry et al. (2002). We then determine... Categories: Data, Data Release - In Progress; Tags: Greater Yellowstone Ecosystem, Greater Yellowstone Ecosystem, Idaho, Montana, United States, All tags...

In order to isolate the effects of any of these stressors on water resources, detailed long-term datasets are crucial. The environmental monitoring network at University of Kentucky’s (U KY) Robinson Forest in eastern Kentucky provides such a resource, with detailed streamflow, water-quality, and precipitation-chemistry data for multiple control and disturbed watersheds covering a 40-year time period. ...
