This model archive provides input and output for Soil-Water-Balance (SWB) models developed to simulate groundwater recharge (net infiltration) for a groundwater model of watersheds on the north shore of the Long Island Sound. The simulated groundwater recharge was further refined in the calibration of the groundwater flow model, which is published in a separate ScienceBase archive (https://doi.org/10.5066/P1HKENGV). The SWB model was run from water year 2004 through water year 2022, which includes a model spin-up year to properly initialize the state of soil moisture for the first year of the desired simulation (water year 2005).
These data are in two tables relating to fall age ratios (number of juvenile birds : total birds aged) of Black Brant (Branta bernicla nigricans) staging in Izembek Lagoon, Alaska, since 1963. The first table is observation data for the age classes of Black Brant during surveys, and associated survey characteristics. The second table contains model-based estimates of age ratios by year along with Standard Error (SE), and 95% Bayesian credible intervals around estimates.

A monthly model of groundwater-transported nitrogen loads was developed for 12-digit hydrologic unit code (HUC12) watersheds on the north shore of Long Island Sound in coastal Connecticut and adjacent areas of New York and Rhode Island. As part of the analysis, potential management actions that upgraded septic systems or reduced fertilizer application to areas of turf-grass were also simulated. This compilation includes a zipped file (Tables.zip) of aggregated model outputs and datasets used in the model development. The zipped file contains a file dictionary (file_dictionary.csv) that includes the file name, title, and caption for each table and a data dictionary (data_dictionary.csv) that includes the variable...

A previously calibrated MODFLOW-NWT groundwater-flow model (https://doi.org/10.3133/sir20205118) was used to determine the effects of climate variability under a range of future climatic conditions on groundwater resources in the reach 1 of the Washita River alluvial aquifer in western Oklahoma. The study area focuses on reach 1 of the Washita River alluvial aquifer; the entire Washita River alluvial aquifer consists of four administrative sections, or reaches, that are designated as reaches 1–4 by the Oklahoma Water Resources Board (OWRB, 2012). To approximate a range in future base-flow conditions in reach 1 of the Washita River alluvial aquifer and base-flow into Foss Reservoir, the Coupled Model Intercomparison...
This data release contains monthly 270-meter gridded Basin Characterization Model (BCMv8) climate inputs and hydrologic outputs for the Salton Sea Watershed, which crosses the international border into Mexico in the southern part of the basin. Downscaled gridded climate inputs (Daly et al., 2008) for the California portion of the BCM (Flint et al, 2021) include: precipitation (ppt), minimum temperature (tmn), maximum temperature (tmx), and potential evapotranspiration (pet). Historical climate data covering the Mexico portion of the watershed was unavailable. Climate data for the California portion of the watershed was regridded using regression techniques described in Flint & Flint (2012) to extend climate inputs...
