The shapefiles depict the valley bottom areas over which HEC-RAS model results were summarized. Valley bottoms were manually delineated in ArcMap by visually interpreting LIDAR terrain models and aerial imagery. Substantial changes in elevation, curvature, and slope were interpreted within the context of their position within the study reach to be channel banks and valley walls. Such areas were excluded from the valley bottom delineation.
The shapefiles depict the 2D HEC-RAS hydraulic modeling domains used for the simulations described in the associated publication. Model domains were delineated in the HEC-RAS geometry editor to encompass river-valley bottoms and adjacent hillslopes of four river reaches of contrasting contributing area and morphology: Seneca Creek at Dawsonville, MD; Patapsco River at Woodstock, MD; Patuxent River at Unity, MD; and Little Gunpowder Falls at Laurel Brook, MD.
Floodplain forest species are presumed to interact strongly with the environment, as evidenced by pronounced spatial variation in flood-driven abiotic constraints and forest composition. These data describe functional diversity and environmental characteristics for 156 forest assemblages sampled on floodplain landforms within transects from the lower peninsula of Michigan. The functional diversity of each assemblage is characterized by two metrics of functional richness (Convex Hull Volume/CHV and Trait Onion Peeling/TOP), one metric of functional dispersion (FDis), and community weighted mean functional trait values. Functional diversity metrics were calculated from 12 quantitative and qualitative functional traits...
Terrain models representing river channel and terrestrial surface elevations were developed for use in 2D hydraulic modeling with HEC-RAS software. Channel bed elevations were determined from cross-sectional field surveys (Seneca Creek and Patapsco River) or manual corrections of the LIDAR data (Patuxent River and Little Gunpowder Falls) and integrated with the terrestrial LIDAR data.
This dataset contains predictions of habitat suitability of reed canarygrass (Phalaris arundinacea) in Upper Mississippi River floodplain forest understories from Pool 3 to Pool 13. Predictions were created using three machine learning algorithms (Bayesian additive regression trees, boosted trees, and random forest). This dataset contains rasters that provide habitat suitability predictions for each 12m raster cell that had forested landcover in 2010. In addition to one raster for each of the three algorithms an ensemble (mean prediction of all three algorithms) prediction raster for each pool is provided. The presence/absence observations used to train the model are contained in a .csv file with each plot location....
Hourly ambient temperature data were collected as part of an effort to empirically evaluate the Upper Mississippi River System inundation model. The goal of this sampling effort was to document inundation through space and time at a limited number of sites but across the range of flow conditions experienced throughout the 2017 growing season. We used temperature data loggers (Onset HOBO Pendant Temperature Data Loggers, model #UA-001-08) to record hourly ambient temperatures at the floodplain’s surface for subsequent analysis of hourly and diurnal flux patterns that would indicate likely submergence. Temperature loggers were deployed in two separate sites within six study segments (Pools 4, 8, 13, 26, La Grange,...

This spreadsheet reports HEC-RAS model parameters and hydrologic data for 2D hydraulic simulations of the four study reaches described in the associated publication. Model parameters include the energy grade slope for distributing flow at the upstream boundary and normal depth friction slope. Hydrologic data include 5 hydrographs per study reach. The hydrographs represent a range of low to high magnitude flooding events based on the historical instantaneous discharge records. To develop the hydrographs, first an aggregate flood event series was extracted by identifying likely overbank flows from the instantaneous discharge record for each study reach. Then, peak discharges during each flood event were temporally...
