East Fork White River near Seymour, IN, processed DEM
Created: Nov. 11, 2020, 4:40 p.m.
Authors: Czuba, Jonathan

ABSTRACT:

This is a lidar DEM originally downloaded from Open Topography, a bathymetric surface has been added to the river from survey data collected in October 2016, and roadways have been cut out at select locations so that water can be conveyed across the floodplain surface at culverts that could not otherwise be added to a 2D HEC-RAS model.

ABSTRACT:

This dataset contains 4 shapefiles:

11Oct2016_DS_AT_Proc.shp
11Oct2016_RTK_WSEL_snap.shp
18Oct2016_DS_AT_Proc.shp
18Oct2016_RTK_WSEL_snap.shp

These data were collected on the 11th and 18th of October 2016, respectively.

...RTK_WSEL_snap.shp -- contain water-surface elevations measured with an RTK GPS providing highly accurate elevation measurements at several locations along the river.

...DS_AT_Proc.shp -- contain depths measured with a depth sounder. The spatial position is approximate and the valid vertical measurement is depth as "Depth_ft_", which is water depth at the time of the survey in feet.

These are a raw form of the data that were used to develop a bathymetric surface used for modeling.

ABSTRACT:

These RTK GPS survey points were collected on 3 March 2017.

The "Code" attribute refers to the following:

"DEBRIS" -- the location of some sort of debris line (corn stalks, leaves, wood) that indicated high water in the past that we believe was tied to a flooding event earlier that January.
"WSEL" -- water-surface elevation at the time of the survey. This marks the extent/location of water on the floodplain at the time of survey.
"ICE" -- the location of ice, the water-surface was higher the previous day and had been receding over night, at some point the water froze to ice, and this marks the location of the water surface when some of the water froze to ice. Not all ice had melted by the morning of the survey.
"MUD" -- locations where the ground was wet and likely had been inundated recently, perhaps marking a high point of flooding from the most recent storm(?)

For the January 2017 high water-marks used by
Czuba, J.A., S.R. David, D.A. Edmonds, and A.S. Ward (2019), Dynamics of surface-water connectivity in a low-gradient meandering river floodplain, Water Resources Research, 55(3), 1849-1870, https://doi.org/10.1029/2018WR023527
only the "DEBRIS" points were used.
