The correct answer is: D. changes with both time and location
Infiltration capacity is the rate at which water can enter the soil. It is
affected by a number of factors, including the type of soil, the amount of vegetation, and the slope of the land. Infiltration capacity can also change over time, due to factors such as rainfall, irrigation, and soil compaction.Option A is incorrect because infiltration capacity is not a constant factor. It can change depending on the conditions at a particular site.
Option B is incorrect because infiltration capacity can also change over time. It is not just a function of the current conditions at a site.
Option C is incorrect because infiltration capacity can also change with location. It is not just a function of the current conditions at a particular site.
Infiltration capacity is an important factor in the design of storm water management systems. It is also important in the design of irrigation systems. By understanding how infiltration capacity changes, engineers can design systems that will effectively manage storm water and irrigation water.
