90 Years of Erosion and Deposition on the Trinity River, Dallas, Texas
The City of Dallas has initiated a design to realign and naturalize an eight mile reach of the Trinity River near downtown that has been relocated, channelized, and straightened over the past 90 years. As part of the channel realignment design process for the Trinity River Corridor project, we conducted historical geomorphic analyses, field measurements of bank erosion and floodplain sediment deposition, and numerical modeling of hydraulic and sediment transport characteristics of the river. Our analyses of bank erosion and lateral channel migration showed limited, localized erosion and relatively low rates of lateral migration. We also determined that the channel has maintained a dynamic equilibrium through a process of localized bank erosion and "repair." Field measurements of deposition rates and topographic analysis of historical floodplain sedimentation showed that there has been limited systematic deposition on the floodplain. These findings provided a critical foundation for the design of the Trinity River Corridor project.
