Final answer:
Proper land drainage takes into account the drainage basin of an area, which is key to controlling surface water and protecting structures from water-related issues.
Step-by-step explanation:
The question deals with the concept of drainage basin, which refers to the area of land where surface water from rain and snow melt drains downhill into a body of water, such as a river, lake, stream, or ocean. Proper drainage of the surface water is essential for the control of water near structures, such as houses, to prevent flooding and water damage.
Key factors in designing effective drainage include understanding the land's topography, soil characteristics, and the local climate. In urban planning, designers may include features like wetlands and lagoons for natural water treatment and flood control. When planning the land drainage around a property, the goal is to manage the water so that it does not negatively impact the structures and to ensure the long-term viability of the land's use.
