Surface-sediment grain-size distributions of the Elwha River delta, Washington, July and August 2023 Hand-grab sample Surface-sediment grain-size data are derived from samples collected on the Elwha River delta, Washington, in July and August 2023 (USGS Field Activity 2023-645-FA). Surface sediment was collected from 76 locations using a small ponar, or 'grab', sampler from the R/V Dogfish in water depths between about 1 and 17 m around the delta. An additional 18 samples were collected by hand at low tide. The grain size distributions of suitable samples were determined using standard techniques developed by the USGS Pacific Coastal and Marine Science Center sediment lab. Andrew Stevens

Digital elevation models (DEMs) of the Elwha River delta, Washington, July and August 2023 Trimble R7 GPS (AS) Digital elevation models (DEMs) of the Elwha River delta were constructed from bathymetric and topographic surveys collected in July and August 2023. Nearshore bathymetry data were acquired using two personal watercraft (PWCs) and a kayak equipped with single-beam echosounders and survey-grade global navigation satellite systems (GNSS) receivers. Topographic data were collected on foot with survey-grade GNSS receivers mounted on backpacks. A total of 1,301,196 individual elevation points were collected between July 30 and August 2, 2023, and used to create DEM surfaces with linear interpolation. A DEM was generated for the entire Elwha River delta with a resolution of 5 m and another DEM that included the river mouth region had a resolution of 1 m. Andrew Stevens
