((The Design of the Vegetation and its Relation With the Local Climate in Karbalaa City))

Abstract

This research aims at revealing the role of the Vegetation in Karbalaa City in Creating moderate local climate through controlling the direct and reflected sun rays and increasing shadow rate. as well as controlling the winds through holding, driving or filtering them, and also its ability to increase humidity rate. The research included three topics, the first of which tackled a theoretical study of the relation between the plants and controlling the local climate in the dry hot cities. The second discussed designing the vegetations in the hot dry areas, the concentration was on the trees for being the most effective vegetable element on creating the local climates. As for the third, it is dedicated to evaluate the local climate of karbalaa city according to the thermal comfort requirements and the relation with the nature of its vegetation. the research reached number of results, the most important of which is that the observation points which were chosen were characterized with high vegetation intensity that showed comfort and cooling degrees for July and January that were more comfortable than in the areas having less vegetation.
