Bases of buildings and dams are spread over a large area. Hence, the pressure exerted by the building on the earth's surface is less. thus reducing the risk of sinking.
Earthen dams have very wide base and suitable to pervious foundation.
Structures built by people or machinery are commonly referred to as "man-made structures" or "human-made structures." These can include a wide range of constructions such as buildings, bridges, roads, and dams. They are designed to serve specific functions and often reflect the engineering and architectural practices of their time.
Dams must hold back water of a certain depth, determined by the height of the dam. The pressure exerted by this water on the dam is dependent in part by its depth, since the base of the dam must be able to hold pressures exerted by the weight of all the water above the base. Since the pressure is greater at the base, the dam is broader at the base.
The scope is very wide - anything to do with buildings and other man-made structures.
Man-made structures include a wide variety of constructions such as buildings, bridges, roads, dams, and tunnels. These structures are designed for various purposes, including residential, commercial, transportation, and recreational needs. Additionally, infrastructure like airports, railways, and power plants also fall under this category, showcasing human ingenuity in creating environments that support modern life.
Downstream of the dams the river would get narrow and shallow and upstream of the dams the river would get wide and deep. In between the dams would vary between the two depending on how much water each dam releases and lakes and ponds would probably form between the dams.
Structural Safety is an international journal devoted to integrated risk assessment for a wide range of constructed facilities such as buildings, bridges, earth structures, offshore facilities, dams, lifelines and nuclear structural systems. Its purpose is to foster communication about risk and reliability among technical disciplines
Shield volcanoes are wide because they are made to function as an island, much to the surprise of many scientists. These volcanoes are enormously big, usually spreading out over 300 miles.
Bulid high buildings, not wide as the land is expensive.{cbd}
This is for stability.
