What specific yield range is associated with gravel soils?

The specific yield range associated with gravel soils is accurately represented by a range of 15-30. This range indicates the volume of water that can be stored and effectively drained from the soil after gravitational forces have acted on it. Gravel soils, characterized by their larger particle size, typically have higher porosity and permeability, allowing them to retain a significant amount of water while enabling rapid drainage.

The specific yield is essential for understanding how well a soil can supply water to plants or manage water runoff, making this knowledge relevant for On-Site Sewage Facilities (OSSF) where adequate drainage and treatment of wastewater are critical. Understanding the yield values associated with different soil types helps in the design and implementation of effective wastewater management systems, ensuring they function properly in various conditions.
