Shapefiles depicting the 2D HEC-RAS hydraulic modeling domains 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.

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...

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.
