Transport of material in an estuary is important for water quality and hazards concern. We studied these processes in the Hudson River Estuary, located along the northeast coast of the U.S. using the COAWST numerical modeling system. A skill assessment of the COAWST model for the 3-D salinity structure of the estuary has been successfully studied in the past, and the present research extended that understanding to look at both physical and numerical mixing. The model grid extends from the south at the Battery, NY to the north in Troy, NY. The simulation is performed from March 25 to July 11, 2005 (111 days).

The GAP National Terrestrial Ecosystems - Ver 3.0 is a 2011 update of the National Gap Analysis Project Land Cover Data - Version 2.2 for the conterminous U.S. The GAP National Terrestrial Ecosystems - Version 3.0 represents a highly thematically detailed land cover map of the U.S. The map legend includes types described by NatureServe's Ecological Systems Classification (Comer et al. 2002) as well as land use classes described in the National Land Cover Dataset 2011 (Homer et al. 2015). These data cover the entire continental U.S. and are a continuous data layer. These raster data have a 30 m x 30 m cell resolution. GAP used the best information available to create the land cover data; however GAP seeks to improve...

The U.S. Geological Survey (USGS), in cooperation with the Arkansas Natural Resources Commission, Arkansas Geological Survey, and the Union County Water Conservation Board, has monitored water levels as a part of an ongoing effort to provide information for management of the Sparta-Memphis aquifer. The USGS has produced reports, at various intervals, to describe groundwater conditions in the Sparta-Memphis aquifer. These datasets provide the locations of and groundwater-level altitudes from 306 wells that were used to construct a potentiometric contour surface of the Sparta-Memphis aquifer. Measurements were made from January through May 2013 and represent synoptic conditions. All wells were cased completely in...

The COAWST modeling system has been used to simulate ocean and wave processes along the of US East Coast and Gulf of Mexico. The grid has a horizontal resolution of approximately 5km and is resolved with 16 vertical terrain following levels. The model has been executed on a daily basis since 2010 with outputs written every hour. Data access is available through a Globus access portal here: https://app.globus.org/file-manager?origin_id=2e58c429-d1cf-4808-85a7-0d8214a4547e&origin_path=%2F References cited: Warner, J.C., Armstrong, Brandy, He, Ruoying, and Zambon, J.B., 2010, Development of a coupled ocean-atmosphere-wave-sediment transport (COAWST) modeling system: Ocean Modelling, v. 35, issue 3, p. 230-244. ...

Marshes may drown if they are unable to accrete sediment at the rate of sea level rise, but predicting the rate of sediment accretion at different marshes is challenging because many processes (e.g. tidal range, wave frequency) and conditions (e.g. available sediment, vegetation density, shape of the marsh edge) impact it. The Coupled Ocean-Atmosphere-Wave-Sediment Transport (COAWST, Warner and others 2019; Warner and others 2010) model was used to simulate three-dimensional hydrodynamics, waves, and sediment transport on a marsh platform in an idealized domain. The computational grid was 400 (20) cells in the cross-shore (along-shore) directions with 10 vertical sigma layers, and a cross-shore horizontal resolution...

The COAWST (Coupled Ocean-Atmosphere-Wave-Sediment Transport) modeling framework was extended to add two key processes that affect marshes, erosion due to lateral wave thrust (LWT) and vertical accretion due to biomass productivity. The testing of the combined effects of integrating these two processes was done by modeling marsh complexes within Forsythe National Wildlife Refuge and the Barnegat Bay (BB) estuary, New Jersey, USA. The simulations were performed first for the month of May 2015 for the entire Barnegat Bay. The Barnegat Bay estuary solution was used to force the two smaller domains that encompass Reedy and Dinner Creeks and are modeled for the same time period.
