This project contains field data and supporting files for a Lagrangian particle tracking (LPT) model at a representative reach on the Osage River, Missouri. Field datasets include a topobathymetric digital elevation model (DEM) for a 5-km reach of the Osage River, water surface elevation profiles, and velocity data collected with acoustic Doppler current profiler (ADCP). Channel topography was generated from data collected by USGS staff from the Columbia Environmental Research Center during single beam sonar surveys of the channel bed and high-resolution Real Time Kinematic Global Navigation Satellite Systems for positioning. Field data was used to generate and validate a Lagrangian Particle Tracking model to evaluate...

This dataset represents elevation data of the beach topography and near-shore bathymetry before placing dredge spoils on the beach at Minnesota Point near the Duluth Entry of Lake Superior, Duluth, Minnesota. The data was acquired using a lidar sensor, single-beam and multibeam sonars. The dataset includes DEMs of the terrestrial beach areas and topobathy (combined terrestrial and bathymetry), LAS and XYZ files of lidar, single-beam, and multibeam point data, and 2-ft contours. Data were collected in cooperation with the U.S. Army Corps of Engineers (USACE), Detroit District, to evaluate movement of placed material and overall change of near-shore bathymetry after beach nourishment.

Topobathy was surveyed during the fall of 2022 for two locations along Minnesota Point, where past beach nourishment (dredge materials) were placed. These topobathymetric surveys of Minnesota Point and Lake Superior are repeat surveys that will be used evaluate movement of placed material and overall change of near-shore bathymetry. The data was acquired using a lidar sensor, and single-beam and multibeam sonars. The data includes DEMs of the terrestrial beach areas and near-shore bathymetries of Lake Superior near the Duluth and Superior entries of Minnesota Point, 2-foot smoothed contours, LAS and XYZ files. Data were collected in cooperation with the U.S. Army Corps of Engineers (USACE), Detroit District.
