Performance evaluation of the Walnut Creek 'soft armor' lining system
As both cities and erosion control legislation continue to grow, the need for cost effective, high performance channel lining systems is becoming even more important than ever. When the City of Austin, Texas (USA) faced this challenge, they sought to use a soft armor lining in lieu of the specified concrete lining along Walnut Creek Tributary 7, Phase I. Located in a largely residential neighborhood, the need to provide good aesthetics at a reasonable price was important to the city. Installed in March 1991, roughly up to 11 meters (36 feet) wide and 350 meters (1150 feet) long, the channel lining system has remained in good condition and continues to provide the benefits of a turf reinforced waterway. This paper provides the background, selection, and long-term performance evaluation of a soft armor channel as an alternative to tradtional hard armor. Data from rainfall events is used to estimate velocity and shear stress exerted on the system over the first five years of performance. Included are also photographs, vegetation progression, chronological data, and field observations from the time of installation in 1991 to the present.
