Abstract:

A hydraulic model investigation will be conducted to evaluate the effects of root system characteristics of three meadow plant communities on simulated bank erosion. The test will determine critical tractive forces for different depth increments of soil samples from Slinkard Valley, Mono County, California, using a hydraulic erosion apparatus. Linear and multiple regression equations will be derived relating rate of erosion to several variables or groups of variables describing root system characteristics, soil cohesiveness, hydraulic parameters, and time. It is hypothesized that, stream bank stability is a function of root system characteristics which vary among different plant communities. Moreover, for various soil types and root system characteristics there are threshold velocities required to detach and remove soil particles.
