Subject	Scour at bridges--Oklahoma. Scour and fill (Geomorphology) Bridges--Conservation and restoration--Oklahoma.
Purpose	Currently the Oklahoma Department of Transportation (ODOT) has a $9 billion backlog in maintenance and construction needs for transportation infrastructure, including bridges and culverts. Approximately 1600 bridges are structurally deficient or functionally obsolete structures. Of these, 162 of Oklahoma’s bridges are over 80 years old. Without additional funding in the next 10 years, that number will grow to 800 bridges over 80 years old. One of the causes of bridge structure deficiency is loss of soil cover at bridge piers caused by stream bed degradation.; This project analyzed the degradation in three tributaries of Washita River which includes Rush Creek and Wildhorse and Salt Creeks. The Washita River has selected portions that experience severe degradation of the riverbed. Field reconnaissance survey of the Washita River indicates that Rush Creek, and Wildhorse and Salt Creeks may be going through severe degradation in specific locations. The purpose of this research is to analyze the flow line data and relate it to the degradation of the Rush, Wildhorse and Salt Creeks at bridge location in the Washita River tributaries. This information may then be used to replace or rehabilitate those bridges that experienced severe degradation.
