Dunbar Creek Open Channel Study
As part of the City of Fort Worth’s Open Channel Study program, Kimley-Horn was tasked with developing new hydrologic and hydraulic models (HEC-HMS and HEC-RAS) for the Dunbar Creek Watershed in Fort Worth, Texas.
The Dunbar Creek Watershed is 960 acres and generates approximately 5,000 cubic feet per second before it converges with the Wildcat Branch and Lake Arlington. Kimley-Horn developed the hydrologic and hydraulic models and used citizen complaints that had been collected and logged to help calibrate the models. The team performed an existing and an ultimate condition floodplain model for the watershed. The results were discussed with the City and areas of flooding were identified and targeted as opportunities for future drainage improvement projects. Once the areas of concerns and the undersized drainage facilities were identified, we developed hydraulic models that determined potential solutions for mitigating the flooding hazards or increasing the capacities of the drainage facilities.
Recommendations were developed and will be implemented as future drainage projects.
