What is the runoff potential characteristic of Type D soils?

Type D soils are characterized by having a high runoff potential due to their properties. These soils are typically heavy clays with low permeability, meaning they do not allow water to infiltrate effectively. The compact, dense structure of Type D soils leads to a situation where rainwater cannot seep into the ground easily, resulting in increased surface runoff during precipitation events. This surface runoff can contribute to erosion and sedimentation issues, as the water carries sediment and pollutants away from the site.

Understanding the runoff potential of different soil types is essential for implementing effective erosion and sediment control measures, especially in construction and land development projects. Proper management strategies must be employed for Type D soils to minimize the risk of flooding and minimize the impact on water quality in nearby water bodies.
