Abstract

The limited areal extent of small countries means that reliance has to be placed on mountainous terrain in developing more land needed for continuous growth. These terrains, especially along the Eastern Mediterranean, usually have rugged morphologies which makes their evaluation difficult. The Australian P.U.C.E. system for terrain assessment and classification proved to be an optimal approach for engineering-geology related studies for the above task in the Aley-Chouf area. Basic land properties having an impact on land development are singled out. They constitute mainly the geological formations, relief, drainage, land forms, soils and the vegetation cover. The land divisions used are Province, Pattern and Unit which cover ten rock formations of varying lithologies, water character and stability features. The area is divided into 7 provinces, 26 terrain patterns and 152 units. These land divisions imply finding similar engineering geological problems and applying similar solutions when planning to develop the area, or some other equivalent areas.

Résumé

La surface limitée des petits pays impose qu'on utilise le terrain montagneux quand on a besoin de développer la terre nécessaire pour la croissance continue. Ces terrains, spécialement au long de l'Est de la Méditerranée, ont des morphologies tourmentées ce qui rend leur évaluation difficile. Le système Australien P.U.C.E. pour l'évaluation et la classification du terrain s'est révélé être le meilleur pour les études de géologie de l'ingénieur afin d'atteindre l'objectif fixé. Les propriétés essentielles qui ont une influence sur le développement des terrains sont mises en évidence. Ce sont essentiellement les formations géologiques, le relief, le drainage, la morphologie, le sol et la végétation. Les divisions utilisées pour le terrain sont «Province», «Pattern», et «Unit» ce qui couvre dix formations de roches de différentes lithologies, caractères hydrogéologiques et aspects de stabilité. La région est divisée en 7 «provinces», 26 «patterns» et 152 «units». Ces divisions impliquent que les problèmes rencontrés lors des travaux de développement ainsi que les solutions à ces problèmes seront voisins dans des zones similaires.
