Which group of soils has low runoff potential and high infiltration rates?

Soils classified as Hydrologic Soil Group A are characterized by their low runoff potential and high infiltration rates. This classification indicates that these soils have a high permeability, which allows water to pass through them quickly, reducing surface runoff. Typically, Group A soils consist of coarse-textured materials like sands and gravels that facilitate rapid drainage and promote deep percolation of water.

This property is crucial in managing water on construction sites and preventing erosion, as high infiltration helps to recharge groundwater supplies and minimizes flooding. Understanding soil characteristics and their behavior in terms of infiltration and runoff is essential for stormwater management practices, especially in areas prone to heavy rain or snowmelt. High infiltration rates are particularly beneficial for sustainable practices aimed at reducing erosion and managing sediment transport.
