These datasets contain results of sediment and contaminant transport (arsenic) simulation for 100-year flood in Woodbridge watershed, NJ. The flood discharge is simulated by HEC-HMS model using 24-hours storm and runoff curve number method. HEC-RAS 2D is used to simulate flood with 48-hours duration. The External Coupler program links HEC-RAS 2D and WASP in an offline and one-way direction. The Coupler is developed in python. The source code, executable file, and users’ manual for the program are available in the External Coupler folder. Using hydrodynamic file generated by the External Coupler, WASP simulated sediment and contaminant transport in flood. This dataset is associated with the following publication: Shabani, A., S. Woznicki, M. Mehaffey, J. Butcher, T. Wool, and P. Whung. A coupled hydrodynamic (HEC-RAS 2D) and water quality model (WASP) for simulating flood-induced soil, sediment, and contaminant transport.

This data release documents the digital data used to produce flood-inundation maps for a range of gage heights (stages) for the Sabinal River near Utopia, Tex. The simulated flood-inundation maps correspond to a range in stage from 7 to 24 feet (ft) at U.S. Geological Survey (USGS) streamgage 08197970 Sabinal River at Utopia, Tex. at intervals of 0.5-ft. The maps were created for a 10-mile reach of the Sabinal River from USGS streamgage 08197936 Sabinal River below Mill Creek near Vanderpool, Tex., at the upstream boundary of the study reach, to USGS streamgage 08197970 Sabinal River at Utopia, Tex. (hereinafter referred to as the “Utopia gage”), at the downstream boundary of the study reach, and 7-mile reach of the West Sabinal River and were created by the USGS in cooperation with the Bandera County River Authority and Groundwater District and with the Texas Water Development Board. Stage data are collected every 5 minutes and used for estimating areas of inundation near the Utopia gage; the stage data are available from the USGS National Water Information System (NWIS) online database at https://dx.doi.org/10.5066/F7P55KJN (gage information are also directly accessible at https://waterdata.usgs.gov/nwis/). The companion interpretive report (larger work citation) accompanying these digital data is Choi, N., 2023, Flood-inundation maps created using a synthetic rating curve for a 10-mile reach of the Sabinal River and a 7-mile reach of the West Sabinal River near Utopia, Texas, 2021: U.S. Geological Survey Scientific Investigations Report 2023–5001, 18 p., https://doi.org/10.3133/sir20235001. Flood profiles were computed for the stream reach by means of a two-dimensional unsteady state diffusion wave model, Hydrologic Engineering Center's River Analysis System (HEC–RAS; Davidian, 1984; U.S. Army Corps of Engineers, 2016a, b, c). The model results were validated using a synthetic stage-discharge relation at the Utopia gage; the synthetic rating curve was developed based on a regional regression equation by Asquith and others (2013). Detailed information about the methods and data used for this analysis are provided in the companion interpretive report.

This dataset includes the one-dimensional HEC-RAS water quality model simulation input and output files for two simulation discharges at the Lazy Day (LD) reach on the Big Piney River near St. Robert, Missouri. Simulations were run for environmental DNA (eDNA) sample collection dates on July 07, 2020 and July 23, 2021. For each eDNA collection date, the transport of freshwater mussel eDNA from Cumberlandia monodonta was simulated by specifying eDNA as an arbitrary constituent in the HEC-RAS water quality module and assigning a first order rate of decay. To account for the variation of the eDNA field samples at the upstream boundary condition, as well as the laboratory derived decay constants, we ran three model simulations for each eDNA collection date: a) the mean eDNA concentration at the upstream boundary with the mean decay constant (k), b) the mean eDNA concentration at the upstream boundary plus 1SE with the mean k minus 1SE, and c) the mean eDNA concentration at the upstream boundary minus 1SE with the mean k plus 1SE. Field collected eDNA concentrations were used as an upstream boundary condition.
