This study related sediment deposition to four residual vegetation heights (0, 0.05, 0.1 m, and unclipped control) on wide arroyo streams. Study plots forty-five meters long included 15 m upstream and downstream buffer zones and four transects perpendicular to the thalweg in the middle 15 m area. Sediment deposition and erosion were measured as differences in elevation from survey readings taken on transects before winter and after unusually high spring runoff events. Treatment effects were insignificant in the first study year (94-95) and significant (p {dollar}leq{dollar} 0.1) in the second study year (95-96). The 0.05 m residual stubble height captured significantly (p {dollar}leq{dollar} 0.1) more sediment than the three other heights. Vegetation characteristics including type, amount, and growth form, and maximum water depth during baseflow and flood conditions correlated poorly with the measured response.
