Study of the landform helps facilitates site planning. Shape of the ground, provision for circulation and vertical elements of planting and enclosure are important factors to be considered in landscape design.
Garden design is a major part of landscape Architecture. Study of the landform helps facilitates site planning and landscape design. Topography and slopes determine framing, screening of views, plant growth with which the former is achieved; siting of built surfaces and artifacts in landscape. However, the topography and the associated slopes when based on geology and soil characteristics assist in economic and sustainable landscape design.
