What is the property of a material or soil that does not allow or easily allow movement of water?

• A. Pervious
• B. Hydraulic
• C. Impermeable
• D. Infiltrative

Answer: (C)

The correct choice is based on the definition of the term "impermeable." A material or soil described as impermeable has a very low permeability, meaning it does not allow water to pass through it easily. This property is crucial in various applications, such as in the construction of landfills, dams, and liners for ponds, where it's necessary to prevent water from seeping through the material. In hydrology, understanding the impermeability of soil is essential for managing groundwater and controlling the flow of water in subsurface environments. The other terms relate to water movement in different ways. "Pervious" describes materials that allow water to flow through them readily, which is the opposite of impermeable. "Hydraulic" refers to the behavior of fluids in motion, often in relation to pressure and flow. "Infiltrative" pertains to the process of water entering into soil or material, indicating a capacity for water movement rather than restriction. These contrasting properties illustrate the significance of identifying and understanding impermeable materials in water management and civil engineering.
