Abstract:

This dataset contains the centerline position for the Mobile River/Tombigbee River system; the thalwegs for the Mobile, Alabama, and Tombigbee Rivers; a listing of all publicly-available data used and their sources; measured and low-pass filtered velocities from stations not directly obtainable online; measured and low-pass filtered water levels from the stations not directly obtainable online. Bed elevations from 119 surveys were used to calculate high-resolution thalweg elevations. The 11 long-term water level and 6 long-term velocity measurements were resampled at hourly intervals as well as low pass filtered with a 9-day Lanczos filter.

Purpose:

Data published here were used to study geomorphology and the propagation of river flood waves (fluvial flood waves) through the Tombigbee-Alabama-Mobile-Mobile Bay fluvial-marine transition in the associated publication, Dykstra & Dzwonkowski (2020).

Data Parameters and Units:

Centerline locations along the Tombigbee-Mobile Transition: Filename: Profile_Mobile-Tombigbee_Location.txt River_Kilometer: kilometers inland from Main Pass along the center of the fluvial-marine transition Longitude: degrees north Latitude: degrees east UTM_Zone: zone of the UTM UTM_x: meters east UTM_y: meters north For original data see geospatial-usace.opendata.arcgis.com/datasets/80a394bae6b547f1b5788074261e11f1_0 Thalweg profile elevations: Filenames: Profile_Alabama.txt, Profile_Tombigbee.txt, Profile_Mobile.txt River_Kilometer: kilometers inland from Main Pass along the center of the fluvial-marine transition Elevation_meter: deepest point of the cross section in meters using the National Geodetic Vertical Datum of 1929 For original data see geospatial-usace.opendata.arcgis.com/datasets/80a394bae6b547f1b5788074261e11f1_0 Water level profile of the 1961 discharge event: Filename: Profile_Mobile-Tombigbee_Water_Level_1961_Event.txt River_Kilometer: kilometers inland from Main Pass along the center of the fluvial-marine transition Elevation_meter: deepest point of the cross section in meters using the National Geodetic Vertical Datum of 1929 For original plot where data was pulled from, see O'Neil, P.

Methods:

For detailed methods, please refer to "data and method" section and the supporting information in the associated publication Dykstra & Dzwonkowski (2020). The station naming convention is detailed in Dykstra & Dzwonkowski (2020) as well; briefly, stations are named after the body of water in which they are located (Alabama, Bay, Delta, Tombigbee) and their distance upstream from the Main Pass.
