Project Examples

US 87 Truck Relief Route

Completed drainage study for the US 87 Truck Relief Route.  The purpose of the study was to analyze areas where increased flooding was reported after the construction of the relief route. The analysis included estimating runoff prior to the construction and comparing to runoff conditions after construction.  Based on these results, evaluated alternatives to mitigate increased runoff.  Design solutions included detention, increased channel capacity and erosion control.  

Secord Dam 2D Analysis

​Completed 2D HEC-RAS analysis to determine the amount of overflow that occurs along the east rim of Secord reservoir during the PMF design storm.  Two models were developed for comparison purposes.  One model was a combination of one-dimensional and two-dimensional flow.  The other model was based entirely on two-dimensional flow.  The results were submitted to FERC and used to determine modifications needed at Secord Dam to safely pass the PMF design storm.  Secord Dam is located in Gladwin County, Michigan 

McLennan County EAPs

Completed simplified and detailed breach analyses based on TCEQ H&H criteria for 26 dams in McLennan County, Texas.  The breach analyses were used to develop inundation mapping  to prepare Emergency Action Plans (EAPs) for each dam.
