Sedimentation Study of Dickinson Bayou Tidal
Purpose/Objectives
The primary objective of this study was to measure total sediment and organic carbon deposition rates at three separate areas of Dickinson Bayou tidal (segment 1103) during at least two sampling events.
Study Area
Dickinson Bayou, Texas
Project Period
2011 – 2012
Description
The primary goal of this project was to collect necessary water, sediment, and sediment chamber data that will be used in future total maximum daily load (TMDL) development tasks, including refinement of the Environmental Fluid Dynamics Code (EFDC) model. The primary objective of this study was to measure total sediment and organic carbon deposition rates at three separate areas of Dickinson Bayou tidal (segment 1103) during at least two sampling events. In order to complete this objective, EIH collected and analyzed ambient water, stream bottom sediment, and recently deposited sediment and particulate-associated total and organic carbon, and nutrients (phosphorus and nitrogen) using sediment traps deployed in segment 1103 during four sampling events, including two wet weather and two dry weather event. These data were used to produce estimates of the sedimentation rates and constants necessary to calibrate dynamic water and sediment quality models.
