Soils in the Type A hydrologic group are characterized by which infiltration and runoff potential?

Soils classified in the Type A hydrologic group are characterized by high infiltration rates and low runoff potential. This classification typically includes sandy soils with a high permeability that allows water to easily percolate and infiltrate into the ground rather than flow over the surface. These soils can absorb a significant amount of water during rainfall events, which minimizes surface runoff and helps to reduce flooding and erosion.

In essence, Type A soils promote efficient water absorption and can recharge groundwater aquifers effectively. This characteristic makes them particularly beneficial for stormwater management and erosion control, as they enhance water quality by filtering pollutants and reducing the volume of runoff that can carry sediment and contaminants into water bodies. Understanding the infiltration and runoff potentials of different soil types is crucial for effective stormwater management practices and ensuring compliance with environmental regulations.
