What does permeability refer to in the context of soils?

Permeability in the context of soils specifically refers to the rate at which water moves through the soil material. It is a crucial property that affects water drainage, pollutant transport, and the overall hydrology of an area. This characteristic is determined by the size and connectivity of the soil pores, which influence how easily water can pass through the soil structure. High permeability means that water can move quickly through the soil, while low permeability indicates that water moves more slowly.

Understanding permeability is essential for landscape architects and planners when designing drainage systems, managing stormwater, and developing sustainable land use strategies. By knowing how permeable a soil is, landscape professionals can make informed decisions regarding site selection, vegetation types, and soil amendments to optimize water movement and management.
