Project: Dayton Valley Bank Stabilization
Client: Dayton Valley Conservation District
Location: Dayton, Nevada
Description:
Site: The site consisted of numerous bank locations along an 8-mile stretch of the Carson River within Dayton that were exhibiting bank failures and loss of valuable agricultural land and in need of stabilization.
Challenge: Property owners along the Carson River were experiencing significant annual erosion of agricultural lands and needed to find viable long-term methods to minimize erosion from annual stream flows. Over the previous years the district had implemented several different solutions on a piece-meal basis, but had no method for ascertaining the effectiveness of any or all of these solutions. The district hired R.O. Anderson to create a viable, long-term bank stabilization solution.
Solution: Our research included conducting an aerial survey of the reach and preparing a hydraulic model to determine depth of flow for various discharge rates/recurrence intervals. In addition, we began a five-year annual monitoring program to record changes in the bed slope at approximately 40 cross-sections at specific and repeatable locations. When the monitoring period is complete, our team will summarize our findings and provide site-specific recommendations for feasible and applicable solutions for future sites.
