Abstract

Roadside amelioration, particularly with trees and shrubs, is an effort to harmonize civil engineering works and environment the vegetation not only introduce noise pollution, but also provides a nice view of the countryside for passengers. The main limitation of this program, especially in arid and semi-arid areas, is the water requirement of plants, as even the most drought-enduring plants need a minimum amount of water for survival. Although the impermeability surface of asphalted roads produce a considerable volume of runoff, the presence of numerous ephemeral watercourses cut by the roads offer an opportunity not only to reduce the flooding hazards and inconveniences of stalled traffic, but also to green the roadsides. The objective of this study was to assess the performance of Eucalyptus camaldulensis Dehnh trees planted by the Nasir Abad-Rahim Abad roadsides (the Gareh Bygone Plain) on 21 February 1985 by the students of the Rahim Abad Elementary School and irrigated with floodwater90 trees were selected and measured their qualitative and quantitative parameters for 4 years. Results indicated that besides a survival rate of 100% in that desert, the height and diameter growth of the trees were spectacular. Therefore, in addition To protection of road, a verdant landscape has been created by providing the water requirement of trees. Rain water harvesting system, is adapted to environment solution for the roadside planting.
