Abstract:

This location and elevation dataset is a combination of a bathymetry survey conducted by the University of South Florida Coastal Research Lab in September 2022, and 2017 NOAA LiDAR data. These data were used to build the numerical model used to simulate flow and erosion and deposition patterns within the Hillsborough River, Tampa, Florida. These two data sets were combined to ensure both the topography dataset and the bathymetry dataset were accurate and of a fine resolution. The echosounder data collected by USF from 2022-09-09 to 2022-10-14 may be downloaded from GRIIDC related dataset B1.x126.000:0001 (https://doi.org/10.7266/j1gj835p).

Purpose:

Basic background data for numerical modeling.

Data Parameters and Units:

Easting (State Plane Florida West, [m]), Northing (State Plane Florida West, [m]), Elevation (NAVD88, [m])

Methods:

Bathymetry data were collected by USF using a precision echo sounder (Odem, narrow angle, single beam) synchronize with a RTK GPS (Trimble R8). The survey was managed using HYPACK ECHO. All the pieces of equipment were mounted on a shallow draft pontoon boat. Land DEM was retrieved from NOAA Data Access Viewer on 2023-04-10. A current link is https://coast.noaa.gov/dataviewer/#/lidar/search/-9183386.627993084,3239952.243082216,-9174819.312627904,3253551.6635870626/details/9457. The NOAA LiDAR DEM was confined to positive elevation and resampled on a 2-m grid of centroids to generate a point scatter. The resampled DEM-based point scatter and the bathymetry point scatter were imported into Coastal Modeling System (CMS) software (developed by US Army Corps of Engineers) and then merged.

Instruments:

Odem echo sounder, RTK GPS (Trimble R8)

Error Analysis:

For the USF data: Equipment errors are specified by the instrument. The equipment specification for both the echo sounder and RTK GPS for the Hillsborough River conditions are within 2 cm. Based on the comparison of data points at the crossing of the cross sections and the along-river lines, the points are mostly within 5 cm. he NOAA airborne LIDAR data should have standard errors for surveys conducted in 2017.
