Abstract
Terracing the slopes involves the level "steps" performing , which ensures a certain percentage out of land to be processed. The main constructive characteristic of a terrace is represented by the platform, respectively its height and counter-slope. The terrace platform is performed with counter-slope which assures the necessary conditions for meteoric water stock and slows down the speed of surface leakage, enabling the growth of wood vegetation (trees, shrubs) and retains the terraced soil. Taking into account the above mentioned, the geometrical elements of a terrace endowed with counterslope should be determined by analytical method, namely- find the total land territory (semi-profile) left (survey), find the total land territory (semi-profile) right (excavation), make the calculation of surface occupied by the terrace total width, calculate the slope length, calculate the transverse profile surfaces and, finally the terraces volume. Determination of geometrical elements (respectively the surfaces covered by total land territory and slopes) is necessary because without them the volume of terracing operations, the volume of material to be dislodged and transport distances cannot be calculated [6]. Once the expressions of geometrical elements of counter slope terrace (starting from terrace total width) determined, the execution time and cost of terracing works, respectively the amount of necessary investments according to digging volume, can be estimated. Algorithm presented may be applied also to agricultural type terraces, whose total width is bigger and are designed to orchards and vineyards.
