Research Project: ESTIMATING HISTORIC FLUVIAL SEDIMENT DEPOSITION IN THE TOBITUBBY AND HURRICANE VALLEYS IN NORTH MISSISSIPPI

Location: Water Quality and Ecology Research

2012 Annual Report


1a.Objectives (from AD-416):
To collect field data of fluvial sediment deposition in the Tobitubby and Hurricane valleys in North Mississippi and to relate historic changes since the 1930s in fluvial sediment deposition to changes in land use.


1b.Approach (from AD-416):
A re-survey will be made of valley cross sections in selected catchments of the Tobitubby (22 km2) and Hurricane (12 km2) watersheds in northern Mississippi which were first surveyed by the U.S. Soil Conservation Service between 1935 and 1941. Several (7) of the 1930's survey beginning and end markers were found in a February 2008 reconnaissance. These sites till be re-surveyed with an RTK-GPS and automatic leveling equipment. Data on historic land use change for both watersheds will be collected from topographic maps, air photographs, and census data. Changes between on-the-ground surveys will be related to land use changes.


3.Progress Report:

FY 12 activities under this project were concluded with some additional field measurements to re-check 2008 elevation measurements of transect in the Hurricane Creek and Tobitubby Creek watersheds that were established in the 1930s. This project yielded two dissertations submitted to the Faculty of Catholic University of Leuven concerned with changes in river morphology and stream valley sedimentation in northern Mississippi between 1930 and 2008.
