Settlement: When a load is applied on the ground, it increases the vertical effective stress. This stress increases the vertical strain in the soil. This increase in vertical strain causes the ground to move downward. This downward movement of the ground is called settlement. Many civil engineering projects include placing of loads on the ground, which produces increase in vertical effective stress. This increase in vertical stress is important because it produces vertical strain in the soil. Subsidence:
Settlement in geography help us to understand manâs relationship with his environment. A rural settlement is a community involved predominantly primary activities such as farming, lumbering and mining. A urban settlement engages in predominantly in secondary and tertiary activities such as food processing and banking. There is often correlation between functions , population sizes and population density. A rural settlement tends to have small population and low population density. Urban settlement often has a large population size and high population density. Site Factors for Settlement. Physical environment determine the site of a settlement depend on
