Scaling the effects of riparian vegetation on cross-sectional characteristics of ephemeral mountain streams - a case study of Nahal Oren, Mt. Carmel, Israel

Description :
To assess the effect of trees and shrubs on stream structure on different spatial scales, the AA. tested the relationships between their percentage coverage in relation to width, depth and stream slope. This research was conducted during the winter and spring of 2004 at Nahal Oren, Israel, an ephemeral mountainous stream. The AA. suggest that shrubs and trees may have a similar function in stabilizing banks via the root system, but the above-ground structure of these vegetative types has different effects. Possibly the dense foliage of the shrubs reduces water velocities, thus further increasing bank stability.
